The cabinet uses a standard metric rackmount bolt pattern with holes on 25 mm (.98 inch) centers. Hinged front and rear doors and removable side panels allow easy access to the cabinet interior. Casters and leveler feet are provided to facilitate placement of the cabinet, and base trim skirts are provided to enhance its appearance. · Shelf brackets--Movable shelf brackets within the cabinet can be configured to hold any of the StorageWorks shelf types. Six shelf positions may be used in the front of the cabinet and four in the rear. Storage shelves may generally be installed in any of the usable shelf positions, although some limitations may be imposed by either weight or cable length restrictions. One shelf position in the rear of the cabinet is reserved for power cable distribution unit (CDU) installation, and one is left open for proper airflow. · SBB shelves--StorageWorks building block (SBB) shelves are designed to house any of the SBBs in the StorageWorks family. The shelves can accept one or two power supply SBBs as well as a number of peripheral device SBBs. SBB shelves provide the mechanical mounting, power, and signal interfaces for the SBBs they house. The shelves are 445 mm (17.5 inch) in width and are designed to slide into the shelf brackets. · SBBs--StorageWorks building blocks (SBBs) are modular computer peripheral devices or power units from the StorageWorks family. SBBs may be disk drives, tape drives, shelf power supplies, battery backup units, or other types of peripherals conforming to the Small System Computer Interface 2 (SCSI-2) specification. They are housed in both 3½-inch and 5¼-inch wide modular carriers designed to plug into slots in SBB shelves. Connectors on the rear of each SBB mate with connectors in the SBB shelf to provide the electrical interface between the two units. · Controller shelves--Controller shelves are StorageWorks shelves designed specifically to house SCSI-2 peripheral controller and cache memory modules. These shelves may also accept one or two power supply SBBs. Controller shelves provide the mechanical mounting, power, and signal interfaces for the units they house. The cabinet allows for the mounting of one controller shelf in the front and one in the rear. Digital's SHZ1Z-ZZ, and SHZ2Z-ZZ controllers are both qualified for use with the SH043-series cabinet. In special situations, different controller types can be installed within the same cabinet. · CDUs--Cable distribution units (CDUs) provide the connections necessary to distribute ac power to the shelves in the SH043 cabinet. CDUs also provide surge and spike protection, along with a circuit breaker to control the incoming ac power. As an option, two CDUs can be configured with an auxiliary ac power source to provide redundant primary power within the cabinet. 1-4 Introduction Figure 1-2 Cabinet Major Components Introduction 1-5 · TZLX-series tape drives--Up to two TZLX-series tape drives can be installed in the upper area of the cabinet, as shown in Figure 1-3. A chassis rail is used to support the tape drive from one side. Figure 1-3 TZLX-Series Tape Drive 1-6 Introduction 1.3 Power Configurations The ac power distribution within the SH043-series cabinet can be configured in one of the following three ways to provide the desired level of power redundancy to the cabinet's shelf-mounted peripheral devices: · Single cabinet power configuration · Dual shelf power configuration · Dual cabinet power configuration A description of each configuration option follows. 1.3.1 Single Cabinet Power Configuration In the single cabinet power configuration, shown in Figure 1-4, a single ac power source and CDU (A) are used to supply ac power to a single ac power supply (A) in each shelf. This is the normal configuration for the cabinet, and it provides no power redundancy to shelf peripheral devices. Figure 1-4 Single Cabinet Power Configuration Introduction 1-7 1.3.2 Dual Shelf Power Configuration In the dual shelf power configuration, shown in Figure 1-5, a single primary power source and CDU (A) are used to supply ac power to two ac power supplies (A and B) in each shelf. If either power supply fails, the shelf remains powered by the other supply. This configuration provides shelf power supply redundancy to the shelf 's peripheral devices. The cabinet supports a maximum of six shelves in the dual shelf power configuration. Figure 1-5 Dual Shelf Power Configuration 1-8 Introduction 1.3.3 Dual Cabinet Power Configuration In the dual cabinet power configuration, shown in Figure 1-6, an auxiliary power source and a second CDU (B) are used to supply ac power to a second ac power supply (B) in each shelf. If the primary power source, CDU A, or ac power supply A fails, the shelf remains powered by ac power supply B. This configuration provides complete power redundancy to the shelf 's peripheral devices. Figure 1-6 Dual Cabinet Power Configuration Introduction 1-9 1.4 Cabinet Cooling System Each StorageWorks shelf contains two rear-mounted blowers that move heat from the shelf into the cabinet interior. The cabinet structure is such that heated air moves from the cabinet interior up and out through the unused shelf positions in the rear. It is then exhausted through the rear door. Logic signals allow the status of the shelf blowers to be monitored by the host system. Filler panels and air separation panels are used to properly route heated air through the cabinet. Filler panels are flat plates that serve as covers for unused shelf positions. Air separation panels are small baffles that mount just above and outside the upper-most shelf in each side of the cabinet to prevent heated air from being drawn down between the cabinet door and the shelf. Such air would be drawn back into the shelf and would interfere with proper cooling. 1-10 Introduction 2 ------------------------------------------------------------ Site Preparation This chapter presents the information necessary to prepare a site for the installation of the StorageWorks SH043-series cabinet. 2.1 General Considerations SH043-series cabinets are intended for installation in Class A computer room environments. Before installing the cabinet, make sure that the following conditions have been met: · The primary power source can supply the required amount of ac power, as specified in Table 1-1. · The site's primary power receptacles are the correct versions for the power plugs provided with the cabinet. The SH043-ZZ cabinet is supplied with a power cable that has an IEC 309 plug.) · The site floor can safely bear the weight of the cabinet, as specified in Table 1-1. Keep in mind that the entire weight of the cabinet is borne by the small surface area of the four leveler feet when the cabinet is installed in its final position. · Adequate space is provided around the cabinet for opening the front and rear doors, for accessing cables, and for adequate airflow. SH043-series cabinets are not designed to be fastened to adjacent cabinets. See Figure 2-1 for specific space requirements. Site Preparation 2-1 Figure 2-1 Minimum Installation Clearances · The cabinet is positioned to allow external interface cables to reach to the appropriate system units. · If the cabinet is to be positioned next to other enclosures, there is sufficient service loop in any connecting cables to allow the cabinet to be moved out for access. 2.2 Equipment Grounding SH043-series cabinets are normally connected to other equipment by one or more interface buses. For both safety and reliable operation, proper grounding is required between the cabinet and other equipment. ------------------------------------------------------------ WARNING ------------------------------------------------------------ If enclosures are not connected to a common ground, there is a potential for a personal injury as a result of electric shock. ------------------------------------------------------------ ------------------------------------------------------------ WARNING ------------------------------------------------------------ When connecting a terminal to a controller within the cabinet, proper grounding is required to prevent personnel injury and equipment damage. For optimum safety and performance, it is recommended that the terminal be powered by one of the two utility IEC outlets on the back of each cable distribution unit (CDU). A spare power cord is furnished with each cabinet for this purpose. ------------------------------------------------------------ 2-2 Site Preparation If ground offset voltages generated in the power distribution system are excessive, data transmission across interface buses can be affected. Significant performance degradation or possible data corruption could result. SH043-series cabinets are shipped with a ground strap (Digital part number 12-13756-A8) that is connected to the rear of the unit. For optimum safety and performance, Digital recommends that the ground strap be connected to the chassis of the host system. Make sure that site power distribution systems meet local electrical codes prior to the installation of SH043-series cabinets. To make sure that the power distribution system will perform satisfactorily, a power system survey should be done before installation. The following areas should be investigated: · Do all outlets have power ground connections? · Do the power cables on all equipment at the site have grounding prongs? · Are all power outlet neutral connections isolated from ground? · Are the grounds for all outlets connected to the same power distribution panel? · Are all devices that are connected to the same breaker as the SH043 cabinet Underwriter 's Laboratories (UL) or International Electrotechnical Commission (IEC) approved? ------------------------------------------------------------ CAUTION ------------------------------------------------------------ If there is a deficiency found in any area during the power survey, a qualified electrician must correct it before installation may begin. Failure to resolve power survey deficiencies before installing the equipment may result in personnel injury as a result of electric shock. ------------------------------------------------------------ If no problems are found during the survey, the site grounding system may be considered to be adequate for personnel safety and reliable SH043-series cabinet operation. Site Preparation 2-3 3 ------------------------------------------------------------ Unpacking and Installation This chapter describes the unpacking, installation, inspection, and powering of StorageWorks SH043-series cabinets. 3.1 Unpacking the Cabinet SH043-series cabinets are packed in a corrugated carton attached to a wooden shipping pallet, as shown in Figure 3-1.

Refer to the appropriate system documentation for initialization procedures. Unpacking and Installation 3-9 4 ------------------------------------------------------------ Configuring SH043 Storage-Only Cabinets This chapter describes the configuration of the SH043 storage-only cabinet. This storage subsystem uses only the StorageWorks SHDZZ-ZZ shelf type. The Small Computer Systems Interface 2 (SCSI-2) interface is used as the communications path between the cabinet's storage devices and their external controllers. SH043 storage-only cabinets can be configured with up to 10 storage shelves. ------------------------------------------------------------ WARNING ------------------------------------------------------------ While working in the cabinet interior, ac power must be removed from cabinet components. Failure to do so may result in personnel injury as a result of electric shock. ------------------------------------------------------------ Prior to performing any of the procedures in this chapter, remove ac power from the cabinet components. If the cabinet is installed and operating, spin down all disk drives and halt all tape drives in the cabinet. Switch the circuit breaker on the front panel of the cabinet's cable distribution units (CDUs) to the (OFF) position. 4.1 Cabinet Configuration ------------------------------------------------------------ WARNING ------------------------------------------------------------ Failure to install cabinet components in the proper order could result in cabinet instability, injury to personnel, and damage to equipment. ------------------------------------------------------------ ------------------------------------------------------------ Note ------------------------------------------------------------ To maintain FCC compliance and proper airflow, filler panels and air separation panels must be installed as specified for your particular cabinet configuration. See Section 4.2 for further information. ------------------------------------------------------------ The order of shelf installation in SH043 storage-only cabinets is predetermined to allow for cabinet loading and cable length factors. Figures 4-1 and 4-2 show the layout of both the front and rear of the storage-only cabinet. To prevent cabinet instability, shelves must be installed in the order shown by the position numbers in the illustrations. Configuring SH043 Storage-Only Cabinets 4-1 4.1.1 Shelf Locations Figure 4-1 shows the proper cabinet rail mounting holes for each shelf location when TZLX-series tape drives are not installed. Shelf mounting hole numbers are counted from the top of each rail. The hole number assignments shown in the figure identify the mounting holes for each shelf 's top bracket screw. See Chapter 6 for detailed procedures pertaining to the mounting of StorageWorks shelves. Figure 4-1 SH043 Storage-only Cabinet Shelf Locations 4.1.2 TZLX-Series Tape Drive/Shelf Locations Figure 4-2 shows the proper cabinet rail mounting holes for each shelf location when TZLX-series tape drives are installed. Mounting hole numbers are counted from the top of each rail. The hole number assignments shown in the figure identify the mounting holes for each shelf 's top bracket screw and for the round standoff chassis rail locating hole for TZLX-series tape drives. See Chapter 6 for detailed procedures pertaining to the mounting of StorageWorks shelves. See Chapter 7 for detailed procedures pertaining to the mounting of the tape drive. Note that the TZLX-series tape drive extends from the front to the rear of the SH043 cabinet and utilize the upper two shelf mounting positions on each side. 4-2 Configuring SH043 Storage-Only Cabinets Figure 4-2 SH043 Storage-only Cabinet Shelf and Tape Drive Locations 4.2 Filler and Air Separation Panels ------------------------------------------------------------ Note ------------------------------------------------------------ To maintain FCC compliance and proper airflow, filler panels and air separation panels must be installed as specified for your particular cabinet configuration and in accordance with the following guidelines. ------------------------------------------------------------ Filler panels can be installed in empty shelf positions to control air flow and electromagnetic emissions and for the purpose of cosmetics. Filler panels are normally supplied and installed based on the specific configuration of the SH043 storage-only cabinet ordered. At least two filler panels are shipped with each cabinet. Install filler panels using the following guidelines: · If a particular filler panel configuration is specified for your cabinet, install the panels exactly as specified. · If a particular filler panel configuration is not specified for your cabinet, use filler panels in all open slots below the highest shelf installed. Repeat for each side of the cabinet. · To ensure proper cooling air flow, never install filler panels above the highest shelf installed in the cabinet. See Chapter 6 for details on the installation of filler panels. Configuring SH043 Storage-Only Cabinets 4-3 Two air separation panels are supplied with each cabinet. Install an air separation panel just above the upper-most shelf in each side of the cabinet. Air separation panels are not required above TZLX-series tape drives. See Chapter 6 for details on the installation of air separation panels. 4.3 Power Configuration The power in SH043 storage-only cabinets can be configured in any of the forms described in Section 1.3. See Chapter 8 for detailed procedures on configuring power within the cabinet. 4.4 Signal Cabling and Routing Signal cabling in the SH043 storage-only cabinet consists of inter-shelf SCSI-2 cabling and shelf-host SCSI-2 controller cabling. 4.4.1 Shelf SCSI-2 Cable Selection and Connection Refer to the StorageWorks Family Configuration Guide and the StorageWorks Family User 's Guide for details on how to select and connect SCSI-2 cables to the cabinet's shelves. 4.4.2 SCSI-2 Cable Routing SCSI-2 signal cables enter SH043 storage-only cabinets through openings in the rear edges of the base pan of the cabinet. Cables destined for rear shelves are normally routed along the base pan to the right-most vertical rail. They are then routed to the the right-hand side of each rear shelf along the rail. SCSI-2 cables destined for front shelves are routed along the base pan and up the right-hand vertical cabinet rail to a point just above the CDUs (refer to Figures 4-1 and 4-2). They then pass into the interior of the cabinet and across to an opening in the vertical chassis rail behind the two right-hand shelf brackets of positions S5 and S10. They pass through the opening and out to the front of the cabinet through the space between the S5/S10 shelf brackets. On the front of the cabinet, cables are normally routed along the right vertical cabinet rail to the right-hand side of each shelf along the rail. Half-meter, SCSI-2 cables are normally used to link adjacent shelves to each other. When TZLX-series tape drives are installed, there is a space between the bottom of the drives and shelf position S4 (refer to Figure 4-2). This space is normally used for the routing of SCSI-2 cables from the rear to the front of the cabinet. 4.4.3 General Cable Routing Rules Cables should be routed and installed with the following rules in mind: ------------------------------------------------------------ WARNING ------------------------------------------------------------ Cabinet rail edges may be sharp and can slice or abrade skin or cable insulation. ------------------------------------------------------------ · Cables should be routed in a manner that allows the shortest overall cable length. · Signal cables should be kept away from power cables. · Care should be taken to avoid sharp cable bends. 4-4 Configuring SH043 Storage-Only Cabinets · Cables should be routed to allow StorageWorks building blocks (SBBs) and controller modules to be freely inserted and removed from their shelves. · Cables should not be routed tightly against the metal edges of the cabinet. · Signal cable bundling along the outside of the cabinet rails should be done to allow the doors to easily close. · Cables should be fastened along cabinet rails using cable ties or nylon cable clamps, U-nuts, and screws. Added cables should be included in existing cable clamps where possible. Configuring SH043 Storage-Only Cabinets 4-5 5 ------------------------------------------------------------ Configuring SH043 Controller/Storage Cabinets This chapter describes the configuration of SH043 controller/storage cabinets. These storage subsystems use StorageWorks HS-family array controllers mounted in SHxzz-zz shelves. Storage devices are housed in SHDZZ-ZZ shelves. StorageWorks HS-family array controllers use the Small Computer System Interface 2 (SCSI-2) interface as the communication path with the host computer. The SCSI-2 interface is used as the storage device bus in all subsystems. SH043 controller/storage cabinets can be configured with up to four controllers in redundant pairs and with up to nine storage shelves.

Filler panels are normally supplied and installed based on the specific configuration of the SH043 controller/storage cabinet ordered. At least two filler panels are shipped with each cabinet. Install filler panels using the following guidelines: · If a particular filler panel configuration is specified for your cabinet, install the panels exactly as specified. · If a particular filler panel configuration is not specified for your cabinet, use filler panels in all open slots below the highest shelf installed. Repeat for each side of the cabinet. · To ensure proper cooling air flow, never install filler panels above the highest shelf installed in the cabinet. Refer to Chapter 6 for details on the installation of filler panels. Two air separation panels are supplied with each cabinet. Install an air separation panel just above the upper-most shelf in each side of the cabinet. Air separation panels are not required above TZLX-series tape drives. Refer to Chapter 6 for details on the installation of air separation panels. 5.3 Power Configuration The power in SH043 controller/storage cabinets can be configured in any of the forms described in Section 1.3. Refer to Chapter 8 for detailed procedures on configuring power within SH043 controller/storage cabinets. 5.4 Host SCSI-2 Signal Cabling and Routing The SCSI-2 interface cables used to communicate with the host are routed directly from the controller to the host. A intermediate bulkhead is not used. 5.4.1 Host SCSI-2 Signal Cable Routing Route the host SCSI-2 interface cables as follows: 1. Route host SCSI-2 cables into SH043 controller/storage cabinets through the openings in the rear edges of the base pan of the cabinet. 2. Route host SCSI-2 cables destined for rear controllers directly up the rear right-hand vertical rail to the rear controller shelf. 3. Route host SCSI-2 cables destined for rear controllers along the base pan to the rear right-hand vertical rail and upward to the pass-through location shown in either Figure 5-1 or 5-2. 5-4 Configuring SH043 Controller/Storage Cabinets 4. Route the cables from the pass-through location to their respective controllers as follows: · Route the cable across the interior of the cabinet to an opening in the vertical cabinet rail behind the two right-hand shelf brackets of positions C1 and S3 (refer to Figures 5-1 and 5-2). · Pass the cable through the opening and out to the front of the cabinet through the space between the C1/S3 shelf brackets to the front controller in position C1. 5.5 Shelf Signal Cabling and Routing 5.5.1 Shelf SCSI-2 Cable Selection and Connection Refer to the StorageWorks Family Configuration Guide and the StorageWorks BA350-EA Modular Storage Shelf User 's Guide for details on the selection of SCSI-2 cables and their connection to the cabinet's shelves. 5.5.2 SCSI-2 Cable Routing SCSI-2 cables from the front controller to the controller 's associated front storage shelves are normally routed along the right-hand vertical cabinet rail to the right-hand side of each shelf. Half-meter, SCSI-2 cables are normally used to link adjacent shelves or tape drives to each other. SCSI-2 cables connecting front shelves to rear shelves pass to the rear of the cabinet via the opening between the right-hand shelf brackets at positions S4 and S9 (refer to Figure 5-1). They pass through this opening and into the interior of the cabinet through the opening in the vertical cabinet rail behind the S4/S9 brackets. They then pass across the interior of the cabinet to the unused shelf position above the CDUs. They pass through the right-hand side of the unused shelf position and along the right-hand cabinet rail to the appropriate rear shelves. When TZLX-series tape drives are installed, there is a space between the bottom of the drives and shelf position S3 (refer to Figure 5-2). This space is normally used for the routing of SCSI-2 cables from the rear to the front of the cabinet. Table 5-1 specifies the SCSI-2 cable length required to connect each controller position with its companion shelves in SH043 controller/storage cabinets. Table 5-1 SH043 Controller/Storage Cabinet SCSI-2 Cable Lengths ------------------------------------------------------------ Controller Position Storage Shelf Position Cable Length Required ------------------------------------------------------------ C1 S1, S2, S3, S4, S9 1.00 m (3.28 ft) C1 S5, S6, S7, S8 2.00 m (6.56 ft) C1 T1, T2 2.00 m (6.56 ft) C2 S5, S6, S8 1.00 m (3.28 ft) ------------------------------------------------------------ Configuring SH043 Controller/Storage Cabinets 5-5 Following are some standard SCSI-2 bus configurations: Shelf connections for single-controller systems with no tape drives are as follow (refer to Figure 5-1): · Single storage shelf C1-S1 C1-S2 C1-S3 C1-S4 C1-S5 C1-S6 · Serially cabled multiple storage shelves C1-S1-S2 C1-S3-S4 C1-S5 C1-S6 C1-S7 Shelf connections for single-controller systems with tape drives are as follow (refer to Figure 5-2): C1-S1 C1-S2 C1-S3 C1-S4 C1-S5 C1-T1-T2 Shelf connections for dual-controller systems with single storage shelves are as follows (refer to Figure 5-1): C1-S1 C1-S2 C1-S3 C1-S4 C1-S9 C2-S6 C2-S8 5.6 General Signal Cable Routing Rules Cables should be routed and installed with the following rules in mind: ------------------------------------------------------------ WARNING ------------------------------------------------------------ Cabinet rail edges may be sharp and can slice or abrade skin or cable insulation. ------------------------------------------------------------ · Cables should be routed in a manner that allows the shortest overall cable length. · Signal cables should be kept away from power cables. · Care should be taken to avoid sharp cable bends. · Cables should be routed to allow SBBs and controller modules to be freely inserted and removed from their shelves. · Cables should not be routed tightly against the metal edges of the cabinet. · Signal cable bundling along the outside of the cabinet rails should be done to allow the doors to easily close. · Cables should be fastened along cabinet rails using cable ties or nylon cable clamps, U-nuts, and screws. Added cables should be included in existing cable clamps where possible. 5-6 Configuring SH043 Controller/Storage Cabinets 6 ------------------------------------------------------------ Installing StorageWorks Shelves This chapter describes the details of the installation of StorageWorks shelves into SH043-series cabinets. Procedures for front and rear shelf installation are presented. The installation of filler panels and air separation panels in both the front and rear of the cabinet are also covered. 6.1 General Shelf Mounting Considerations ------------------------------------------------------------ Note ------------------------------------------------------------ In the following descriptions and procedures, the terms front and rear are references to locations in the cabinet. The terms inner and outer are references to positions on the shelf brackets. ------------------------------------------------------------ Each StorageWorks shelf is mounted in the cabinet with a bracket set (BA35x- RB) (Refer to Figure 1-2.) Each bracket set consists of a pair of shelf brackets, stop brackets, and locking brackets. (A typical bracket set is shown in Figure 6-2.) The stops are attached to the inner portion of the shelf brackets to position the shelf within the bracket. The locking brackets fix the shelf in place. Various combinations of stop positions and locking bracket size are necessary to situate a particular shelf for proper clearance from the cabinet doors. The same shelf bracket and stop bracket parts are used to mount all types of StorageWorks shelves in all locations. The bracket set for shelves mounted in various positions in the cabinet differs only in that the locking brackets are unique parts sized for specific cabinet positions. Filler panels are installed in some unused shelf positions in the cabinet. Filler panels are normally installed after shelf installation An air separation panel is required in both the front and rear of the cabinet to prevent the recirculation of heated air to the cabinet's shelves. The air separation panels are mounted just above the upper-most shelf in each side of the cabinet. Air separation panels are normally installed after shelf installation. ------------------------------------------------------------ WARNING ------------------------------------------------------------ While working in the cabinet interior, ac power must be removed from cabinet components. Failure to do so may result in personnel injury as a result of electric shock. ------------------------------------------------------------ Prior to performing any of the procedures in this chapter, remove ac power from the cabinet components.

The chassis rail is attached to the cabinet's internal vertical rails, and it supports the TZLX-series tape drive from one side. Grooves machined into the side of the tape drive enclosure mate with flanges along the sides of the chassis rail, allowing the tape drive to be slid onto the chassis rail from the front of the cabinet. Once installed, the tape drive enclosure extends from the front to the rear of the SH043 cabinet. Two TZLX-series tape drives can be mounted side-by-side at a given vertical position in the cabinet. The chassis rail hardware is the same for both the left and right mounting positions. Only the orientation of the hardware differs between the two mounting positions. There is no mechanical connection between two tape drives mounted side-by-side in the cabinet. In situations where only one TZLX-series tape drive is being installed at a given vertical position in the cabinet, the tape drive must be installed in the right mounting position. This will ensure that the front panel of the tape drive mates with the correct opening in the tape bezel in the cabinet door. A filler panel in the tape bezel covers the left mounting position in this case. ------------------------------------------------------------ WARNING ------------------------------------------------------------ While working in the cabinet interior, ac power must be removed from cabinet components. Failure to do so may result in personnel injury as a result of electric shock. ------------------------------------------------------------ Prior to performing any of the procedures in this chapter, remove ac power from cabinet components. If the cabinet is installed and operating, spin down all disk drives and halt all tape drives in the cabinet. Switch the circuit breaker on the front panel of the cabinet's CDU(s) to the (OFF) position. Installing TZLX-Series Tape Drives 7-1 Figure 7-1 TZLX-Series Tape Drive Installation 7.2 Accessing the Cabinet Rack Space TZLX-series tape drives can normally be installed without removing cabinet side panels. To route the cabling in configurations where access to the interior of the cabinet is limited, however, cabinet side panels may need to be removed. Sections 7.2.1 and 7.8 present procedures for removing and replacing exterior cabinet panels. The front and rear cabinet doors are held closed by door locks mounted on each door. The locks are released by turning counterclockwise with a 5/32-inch hex wrench. 7-2 Installing TZLX-Series Tape Drives 7.2.1 Removing the Cabinet Side Panels As shown in Figure 7-2, there are three side panel hanger clips on each side of the cabinet. A matching set of hanger clips are attached to each side panel. Remove the side panels as follows: Figure 7-2 Cabinet Side Panel Removal and Installation Installing TZLX-Series Tape Drives 7-3 1. Move the cabinet away from adjacent enclosures as necessary. 2.

Additional information on power configuration options can be found in Section 1.3. 8.1 General Considerations ------------------------------------------------------------ WARNING ------------------------------------------------------------ While working in the cabinet interior, ac power must be removed from cabinet components. Failure to do so may result in personnel injury as a result of electric shock. ------------------------------------------------------------ Prior to performing any of the procedures in this chapter, remove ac power from the cabinet components. If the cabinet is installed and operating, spin down all disk drives and halt all tape drives in the cabinet. Switch the circuit breaker on the front panel of the cabinet's cable distribution units (CDUs) to the (OFF) position. 8.2 Cable Distribution Units The 887-E CDU is used with SH043-series cabinets and is designed for both 230 volt, 50 Hz and 120 volt, 60 Hz applications. The unit provides ac power to the cabinet's components via 12 Molex output connectors on its rear panel. Two International Electrotechnical Commission (IEC) output connectors are also provided for utility purposes. ------------------------------------------------------------ WARNING ------------------------------------------------------------ If the leakage current of the cabinet is above 3.5 mA after installation, Digital recommends that power cables with industrial type B, IEC 950 connectors be installed. Failure to reduce the leakage current can result in equipment performance degradation and personnel injury due to electric shock. ------------------------------------------------------------ Table 8-1 lists the power cables used with the 887-E CDU.

The power cord is connected to the rear panel of the CDU and may be found coiled up in the base of the cabinet. 8.4 Single CDU Configurations Using one CDU, cabinet power can be configured with both single and dual power supplies in each shelf. Refer to Sections 1.3.1 and 1.3.2 for further information on these configurations. 8.4.1 Single Cabinet Power Configuration Unless options are specified, SH043-series cabinets are shipped with a single CDU and single-shelf power supplies. For ease of upgrade, the cabinet is supplied with 10 black and 10 gray preinstalled ac power cords. One black and one gray power cord is routed to each usable front and rear shelf position. These cords are used to supply ac power to shelves as they are added to the cabinet. The black cord at each newly added shelf 's mounting position needs only to be plugged into the shelf 's power supply to complete the shelf 's installation. 8.4.2 Dual Shelf Power Configuration In the dual shelf power configuration, a second ac power supply is necessary for each shelf. (Refer to Figure 1-5.) Configure each shelf for dual ac power supplies as follows: 1. Power the cabinet down as described in Section 8.1. 2. Plug in a second ac power supply (B) next to the existing ac power supply (A) in each shelf. 3. Plug the gray ac power cord at each shelf position into the connector on the newly added ac power supply. 4. Connect the CDU primary power cable to its power source. 5. Using the procedures appropriate to your system, turn on the cabinet and initialize it. 8-2 Power Configuration 8.5 Dual Cabinet Power Configuration The dual cabinet power configuration requires two CDUs for power distribution. The second CDU (CDU B) is installed immediately above CDU A in the rear of the cabinet. Refer to the StorageWorks SH043-Series Data Center Cabinet Cable Distribution Unit Installation Guide for procedures pertaining to the installation of dual CDUs. The installation guide is shipped as part of the dual power option kit.
