The cabinet uses a standard metric rackmount bolt pattern with holes on 25 mm 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 appearance. The cabinet provides 20 horizontal and 4 vertical shelf positions. Storage or controller shelves may generally be installed in any of the shelf positions, although some limitations may be imposed by cable length restrictions. The lower vertical shelf positions in the front and rear of the cabinet are each reserved for power cable distribution unit (CDU) installation and cable routing. · Shelf brackets--Movable shelf brackets within the cabinet can be configured to hold any of the StorageWorks shelf types. Shelf brackets must be procured separately from the cabinet or may come packaged with cabinet options. · 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 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 (BBUs), 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 the 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. · CDUs--Cable distribution units (CDUs) provide the connections necessary to distribute ac power to the shelves and fans within the SW800 data center 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. One CDU can be installed in the lower vertical opening in each side of the cabinet. 2-4 Introduction Figure 2-2 Cabinet Major Components Introduction 2-5 · TZ8x7-Series Tape Drives-Up to four TZ8x7-series tape drives can be installed in the upper area of the cabinet, as shown in Figure 2-3. A chassis rail is used to support the tape drive from one side. Figure 2-3 TZ8x7-Series Tape Drive 2-6 Introduction 2.3 Power Configurations The ac power distribution within the SW800-series data center cabinet can be configured in one of the following three ways to provide the desired level of power redundancy to the shelf-mounted peripheral devices: · Single-cabinet power configuration · Dual-shelf power configuration · Dual-cabinet power configuration A description of each configuration option follows. 2.3.1 Single-Cabinet Power Configuration In the single-cabinet power configuration, shown in Figure 2-4, 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 2-4 Single-Cabinet Power Configuration Introduction 2-7 2.3.2 Dual-Shelf Power Configuration In the dual-shelf power configuration, shown in Figure 2-5, 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. Up to 12 shelves can be configured with dual shelf power from one CDU. An additional CDU, powered also from the primary AC power source, can be installed to accommodate up to 24 shelves with this power configuration. Figure 2-5 Dual-Shelf Power Configuration 2-8 Introduction 2.3.3 Dual-Cabinet Power Configuration In the dual-cabinet power configuration, shown in Figure 2-6, 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. Up to 24 shelves can be configured in this manner. Figure 2-6 Dual-Cabinet Power Configuration Introduction 2-9 2.4 Cabinet Cooling System The SW800-series data center cabinet contains airflow devices in both the shelves and the cabinet itself. Each StorageWorks shelf contains two rear-mounted blowers that move heat from the shelf into the cabinet interior. Six fans in the top of the cabinet draw air up through the center of the enclosure to blow the interior heat out through the top. Logic signals allow the status of the shelf blowers to be monitored by the host system. The cabinet fans are powered in two groups of three fans each. For single-CDU systems, both sets of fans are powered from the single CDU. To ensure a level of cooling redundancy in dual-CDU systems, each CDU powers a separate set of three fans. Filler panels are flat plates that serve as covers for unused shelf positions. 2-10 Introduction 3 ------------------------------------------------------------ Site Preparation This chapter presents the information necessary to prepare a site for the installation of the StorageWorks SW800-series data center cabinet. 3.1 General Considerations SW800-series data center 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 2-1. · The site's primary power receptacles are the correct versions for the power plug(s) provided with the cabinet. Figure 3-1 specifies the cabinet primary power plugs supplied for both 60 and 50 Hz power. Figure 3-1 CDU Primary Power Plugs · The site floor can safely bear the weight of the cabinet, as specified in Table 2-1. 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. Site Preparation 3-1 · Adequate space is provided around the cabinet for opening the front and rear doors, for accessing cables, and for adequate airflow. SW800-series data center cabinets are not designed to be fastened to adjacent cabinets. See Figure 3-2 for specific space requirements. Figure 3-2 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. 3.2 Equipment Grounding SW800-series data center 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 personal injury as a result of electric shock. ------------------------------------------------------------ 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. 3-2 Site Preparation Make sure that site power distribution systems meet local electrical codes prior to the installation of SW800-series data center 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 cords 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 SW800 data center cabinet UL or 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 personal 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 safety and reliable SW800-series data center cabinet operation.

Added cables should be included in existing cable clamps where possible. Figure 5-4 shows the cabinet areas in which cable routing is allowed. Configuring SW800 Storage-Only Cabinets 5-7 Figure 5-4 SW800 Storage-Only Cabinet Cable Routing 5-8 Configuring SW800 Storage-Only Cabinets 6 ------------------------------------------------------------ Configuring SW800 Controller/Storage Cabinets This chapter describes the layout and configuration of SW800 controller/storage data center cabinets. These cabinet configurations use StorageWorks HSJ40(TM) or HSZ40(TM) array controllers mounted in BA350-Mx shelves. Storage devices are housed in BA350-Sx shelves. SW800 controller/storage cabinets can be configured with up to eight controllers in redundant pairs, up to eighteen storage shelves, and up to four TZ8x7 tape drives. 6.1 HSJ40 and HSZ40 Controllers The HSJ40 Controller uses Digital's CI(TM) interface as the communication path with the host computer, and the Small Computer System Interface 2 (SCSI-2) as the storage device bus. Factory preconfigured cabinets using the HSJ40 controller are designated by the model number SW81x. The HSZ40 controller uses the SCSI-2 interface as the communication path with the host computer, as well as for the storage device bus. The configuration of HSJ40 and HSZ40 cabinets is almost identical. The only difference is the host interface cable used, and the fact that a StorageWorks DWZZA SCSI signal converter may be used with the HSZ40 controller. Refer to the StorageWorks Array Controller HS Family of Array Controllers User 's Guide and the StorageWorks BA350-MA Controller Shelf User 's Guide for further information on HSJ40 and HSZ40 controllers and their installation. 6.2 Cabinet Configuration ------------------------------------------------------------ WARNING ------------------------------------------------------------ While working in the cabinet interior, ac power must be removed from cabinet components.

Procedures for horizontal and vertical front and rear shelf installation are presented. There are two types of shelf brackets: shelf brackets with screw mounts and shelf brackets with tab mounts. 7.1 General Shelf Mounting Considerations ------------------------------------------------------------ Note ------------------------------------------------------------ In the following descriptions and procedures, the terms front and rear refer to locations in the cabinet. The terms inner and outer refer to positions on the shelf brackets. ------------------------------------------------------------ Each metric bracket set consists of a pair of shelf brackets, stop brackets, and locking brackets. See Figure 7-2 for examples of these components. There are two types of shelf brackets: shelf brackets with screw mounts and shelf brackets with tab mounts. The stop brackets are attached to the inner portion of the shelf brackets to position the shelf within the brackets. 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 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. 7.2 Shelf Bracket Types SW800 cabinets can come preconfigured with screw-mounted or tab-mounted shelf brackets. Cabinets that have been field modified can contain both types of shelf brackets. See the following descriptions to determine your cabinet configuration. Installing StorageWorks Shelves 7-1 7.2.1 Screw-Mounted Shelf Brackets A typical screw-mounted bracket set is shown in Figures 7-2 and 7-8. The shelf bracket used in this set can be identified by the two screw holes between the front of the bracket and the stop bracket screw holes. In the horizontal position, the screw-mounted brackets are attached to the vertical cabinet rails with six screws. In the vertical position, the screw-mounted brackets are attached to the horizontal cabinet bracket with six screws. 7.2.2 Tab-Mounted Shelf Brackets A typical tab-mounted bracket set is shown in Figures 7-4 and 7-10. The shelf bracket used in this set can be identified by the formed metal slot with four mounting tabs between the front of the bracket and the stop bracket screw holes. In the horizontal position, the tab-mounted brackets are attached to the vertical cabinet rails with four M5 KEP nuts and four mounting tabs. In the vertical position, the tab-mounted brackets are attached to the horizontal cabinet bracket with four M5 KEP nuts and four mounting tabs. 7.2.3 Horizontal Cabinet Brackets on the Vertical Slots Before installing a shelf bracket kit in the vertical position in a SW800 cabinet, determine the type of horizontal cabinet bracket. The type of horizontal cabinet bracket determines which type of shelf bracket kit is compatible. There are two types of horizontal cabinet brackets; a set of two narrow brackets or a one-piece bracket: · Type 1: Two narrow brackets, one attached to the front vertical cabinet rails and the other attached to the interior vertical rails. The rear bracket has two holes with captive floating nuts. Type 1 horizontal cabinet brackets accept only screw-mounted shelf brackets. To install tab-mounted shelf brackets in a cabinet with type 1 horizontal cabinet brackets, see Section 7.7.2 for cabinet configuration differences and Section 7.7.3 for cabinet modification procedures. · Type 2: A one-piece bracket that attaches to the vertical cabinet rails and has four holes at the rear where the shelf bracket's mounting tabs are inserted. The type 2 horizontal cabinet bracket accepts either the screw-mounted or tab-mounted brackets. 7.3 Shelf Bracket Kit Configurations Before mounting the metric shelf bracket kit, check the contents of the bracket kit against the parts list. See Table 7-1 for the SW800 Metric Shelf Screw-Mounted Bracket Kit Parts List.

If the cabinet is installed and operating, spin down all disk drives and halt all tape drives in the cabinet. 2. Remove ac power from cabinet components by switching the circuit breaker on the front panel of the cabinet's power controllers or cable distribution units to the OFF or position. After you have made sure that all the parts are present and that ac power has been removed from the cabinet components, you can begin shelf installation. 7.5 Accessing the Cabinet Rack Space In maximum configurations when access to the interior of the cabinet is limited, external cabinet panels might need to be removed before shelves can be installed or reconfigured. Section 7.5.1 presents procedures for removing exterior cabinet panels. The front and rear cabinet doors are held closed by door locks mounted on the smooth vertical panel of each door. The locks are released by turning counterclockwise with a 5/32-inch hex wrench. 7.5.1 Removing the Exterior Cabinet Panels As shown in Figure 7-1, 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: 7-4 Installing StorageWorks Shelves Figure 7-1 Exterior Cabinet Panel Removal and Installation Installing StorageWorks Shelves 7-5 1. Move the cabinet away from adjacent enclosures as necessary. 2. Loosen the top cover by pushing up on its front and rear edges until it snaps free of its fasteners. ------------------------------------------------------------ WARNING ------------------------------------------------------------ The top cover is heavy and awkward to lift. Removing it requires two people. Failure to use sufficient personnel can result in personnel injury or equipment damage. ------------------------------------------------------------ 3. Using two people, lift the top cover from the cabinet and set it aside. 4. Remove the bolts attaching the side panels to the top side rails of the cabinet. 5.

The chassis rail is attached to the cabinet's internal vertical rails, and it supports the TZ8x7-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 SW800 data center cabinet. Two TZ8x7-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 TZ8x7-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 door 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 personal 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 TZ8x7-Series Tape Drives 8-1 Figure 8-1 TZ8x7-Series Tape Drive Installation 8.2 Accessing the Cabinet Rack Space TZ8x7-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 and 8.8 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. 8-2 Installing TZ8x7-Series Tape Drives Removing the Cabinet Side Panels As shown in Figure 8-2, 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 8-2 Cabinet Side Panel Removal and Installation Installing TZ8x7-Series Tape Drives 8-3 1. Move the cabinet away from adjacent enclosures as necessary. 2. Loosen the top cover by pushing up on its front and rear edges until it snaps free of its fasteners. ------------------------------------------------------------ WARNING ------------------------------------------------------------ The top cover is heavy and awkward to lift. Removing it is a two- person task. Failure to use sufficient personnel may result in injury or equipment damage. ------------------------------------------------------------ 3. Using two persons, lift the top cover from the cabinet and set it aside. 4. Remove the bolts attaching the side panels to the top side rails of the cabinet. 5. Grasp a panel along its front and rear edges and lift up until the hanger clips disengage. Lift the panel away from the cabinet. 6. Repeat the previous step to remove the other panel. 8.3 Chassis Rail Installation As shown in Figure 8-3, one end of the tape drive chassis rail is extendable using a sliding rail bracket, to allow the length of the chassis rail to be adjusted to fit the cabinet. Two round standoffs are used to locate the chassis rail along the vertical cabinet rails. The round standoffs are inserted into front and rear chassis rail locating holes to position the chassis rail while it is fastened to the cabinet. Chassis rail component assembly and installation procedures for both left and right tape drive mounting positions are presented in Sections 8.3.1, 8.3.2, and 8.3.3. ------------------------------------------------------------ Note ------------------------------------------------------------ Two small ESD grounding posts are provided with the cabinet. One is located on a front vertical cabinet rail, and one on a rear rail. Should an ESD grounding post interfere with the installation of the chassis rail, move the post out of the way to any free hole on the cabinet. ------------------------------------------------------------ 8.3.1 Chassis Rail Assembly Before the chassis rail components can be mounted in the cabinet, they must be assembled.

Descriptions of the cabinet's power configuration options can be found in Section 2.3. 9.1 General Considerations ------------------------------------------------------------ WARNING ------------------------------------------------------------ While working in the cabinet interior, ac power must be removed from cabinet components. Failure to do so may result in personal 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. 9.2 Single CDU Configurations Using one CDU, cabinet power can be configured with both single and dual power supplies in each shelf. Refer to Sections 2.3.1 and 2.3.2 for further information on these configurations. The CDU in single-CDU configurations, CDU A, is installed in the position shown in Figure 9-1. Power Configuration 9-1 Figure 9-1 CDU Locations 9.2.1 Single-Cabinet Power Configuration Unless options are specified, SW800-series data center cabinets are shipped with a single CDU and are cabled for single shelf power supplies. The cabinet is supplied with 24 preinstalled, black ac power cables. One of these cables is routed to each front and rear shelf position. These cables are used to supply ac power to shelves as they are added to the cabinet. The cables need only to be plugged into each shelf 's power supply to complete the shelf 's installation. No additional cables are necessary for this configuration. 9.2.2 Dual-Shelf Power Configuration In the dual-shelf power configuration, a second ac power cable and ac power supply are necessary for each shelf. (Refer to Figure 2-5.) Configure each shelf for dual ac power supplies as follows: 1. Power the cabinet down as described in Section 9.1. 2. Plug in a second ac power supply (B) next to the existing ac power supply (A) in each shelf. 3. For cabinets with 12 or fewer shelves, ac power cables preinstalled at unused shelf positions may be used to supply power to the newly-added ac power supplies. For each newly-installed shelf, locate a preinstalled, black power cable of the proper length at an unused shelf position and remove it from any cable clamps holding it to the cabinet. For cabinets with more than 12 shelves, a second CDU is needed to provide dual shelf power throughout the cabinet. A complete set of ac power cables of the proper lengths is supplied with the additional CDU. The ac power cables for each shelf location must be of a minimum length to 9-2 Power Configuration reach the cabinet's CDU(s) along assigned routing paths. Refer to the chapter pertaining to your cabinet configuration for information on ac power cable lengths for various shelf locations. 4. Once the cables are selected, plug the appropriate end of each ac power cable into a connector on the rear panel of the CDU. Choose the upper-most available connector and work down. If necessary, loosen the bracket locking screw and rotate the CDU safety bracket to the side to facilitate installing the cables, as shown in Figure 9-2. After the ac power cables are installed, make sure to rotate the safety bracket back into position over the cable connectors, and to tighten the bracket locking screw. Figure 9-2 Safety Bracket Rotation 5. Route an ac power cable to the second dc power supply (B) in each shelf. Use the existing power cable routing and cable clamps or ties. Plug the cable connector into the front of the power supply. 6. Using the procedures appropriate to your system, turn on the cabinet and initialize it. Power Configuration 9-3 9.3 Dual-Cabinet Power Configuration The dual-cabinet power configuration requires two CDUs for power distribution. The CDUs are installed in the positions shown in Figure 9-1. The following procedure describes how to install the dual-power option kit. 1.

See Figure 9-1 to familiarize yourself with the location and identification of each of the CDUs to be configured for the dual-power option. 3. Spin down all disk drives and halt all tape drives in the cabinet. 4. Open the rear cabinet door to expose CDU A. 5. Switch the circuit breaker on the front panel of the CDU to the (OFF) position. 6. Disconnect the CDU's primary power cable from the power source. 7. Isolate the cabinet electrically by powering down the host computer. ------------------------------------------------------------ Note ------------------------------------------------------------ In some cases, it may be desirable to allow the host computer system to operate while the dual-power option kit is being installed. In this instance, the cabinet may be isolated from power by disconnecting the host computer interface cable(s). Refer to the documentation for the host computer configuration for the steps necessary to disconnect the cables. ------------------------------------------------------------ 8. To install CDU B, you must have free access to the interior area of the front and rear CDU mounting slots. If necessary, gain access to the cabinet interior by separating the cabinet from adjacent ones and removing its side See Chapter 7 for details on cabinet hardware. ------------------------------------------------------------ WARNING ------------------------------------------------------------ Cabinet rail edges may be sharp and can slice or abrade skin and cable insulation. ------------------------------------------------------------ 9. Remove the new CDU (to be installed as CDU B) from its packing material. Thread the primary power cable through the cabinet as shown in Figures 9-3 and 9-4. 10. Using the hardware provided in the kit, mount CDU B to the cabinet chassis rails as shown in Figure 9-3. Power Configuration 9-5 Figure 9-3 CDU B Installation ------------------------------------------------------------ Note ------------------------------------------------------------ To prevent confusion resulting from the fact that the cabinet uses two power cables with the dual-power option, it is important that safety labels be properly applied. Install the cable and cabinet labeling carefully in accordance with the instructions in steps 11 through 15. ------------------------------------------------------------ 11. Remove one of the yellow ``A'' labels in the kit from its backing paper and place it on the lower inside panel of the rear cabinet door as shown in Figure 9-5. 12. Remove another of the yellow ``A'' labels in the kit from its backing paper and wrap it around the plug end of the primary power cable of CDU A as shown in Figure 9-4. 13. Remove one of the yellow ``B'' labels in the kit from its backing paper and place it on the lower inside panel of the front cabinet door as shown in Figure 9-5. 9-6 Power Configuration Figure 9-4 Power Cable Routing 14. Remove another of the yellow ``B'' labels in the kit from its backing paper and wrap it around the plug end of the primary power cable of CDU B as shown in Figure 9-3. 15. Remove the two yellow ``CAUTION'' labels from their backing papers and place them at eye level on the inside of each door as shown in Figure 9-5. 16. Make sure that the second dc power supply required for the dual-power option is installed in each shelf. 17. A complete set of gray ac power cables of various lengths is supplied in the kit. The ac power cables for each shelf location must be of a minimum length to reach CDU B. Refer to Chapter 5 or 6 to determine the correct cable length for each shelf. Power Configuration 9-7 Figure 9-5 Safety Label Locations 18. Loosen the safety bracket locking screw on CDU B and rotate its safety bracket away from the cables to be connected to it, as shown in Figure 9-2. 19. Plug the gray cable of the appropriate length into the second dc power supply in each shelf and route the cable to CDU B. (The second dc power supply is the right one for horizontal shelves, and the lower one for vertical shelves.) Route each added cable to CDU B along the same path as the shelf 's existing black ac power cable. Attach the added cable to the cabinet rails using the existing cable clamps where possible. Use the additional cable ties, cable clamps, and mounting hardware provided in the kit where needed. 20. Connect the gray power cable(s) to the connector(s) on the rear panel of CDU B, starting at the top-most connector and working down. 21. Locate the cabinet fan power cords plugged into CDU A. One is labelled "A" and one "B", each with large, yellow labels. Unplug the cord labeled "B". Loosen the safety bracket on CDU A and rotate it out of the way to facilitate unplugging the cord as necessary. Make sure to return the safety bracket to the operating postion if you move it. 9-8 Power Configuration 22. Plug the fan power cord labeled "B" into a free outlet on the rear panel of CDU B. 23. Rotate the safety bracket back into position over the rear panel of CDU B and tighten the bracket locking screw. 24. If the cabinet's host computer interface cable(s) was disconnected in step 7, reconnect the cable(s). 25. Replace the cabinet side panels and reposition the cabinet next to the adjacent ones as appropriate. 26. Reconnect the primary power cable from CDU A to its source. 27. Connect the primary power cable from CDU B to the auxiliary power source. 28. Switch the circuit breakers on both CDUs to the j (ON) position. 29. Close and secure the cabinet doors. 30. Restart all disk and tape drives and check them for proper function.

All activity on the device's SCSI bus must normally be halted for the duration of the warm swap operation. write through cache A technique for handling host write requests in read caches. When the host requests a write operation, the cache writes data directly to the external storage device and updates the cache memory to ensure that the memory does not contain obsolete data. This technique increases the chances that future host read requests can be filled from the cache. The host sees the write operation as complete only after the external storage device has been updated. See also read cache. write-back cache A cache configuration that increases the performance of host write requests. When the host requests a write operation, the cache writes the host's data first to the cache memory, completing the host's request quickly. It performs the slower operation of flushing the data to the external storage device at a later time. The host sees the write operation as complete when the data has reached the cache.
