The BA430/BA440 consists of the following: · Pedestal system · Dual front door access · Mass storage shelf for tape and disk integrated storage devices · System control panel (SCP) · Enclosure card cage · Power supply · Fan tray · Backplane · Power cord BA430/BA440 Enclosure Description 1-1 Figure 1-1: BA430/BA440 Pedestal Enclosure 1.2 Enclosure Keylock Access To gain access to the BA430/BA440 enclosure, there is a three-position lock that determines which controls you can access (Figure 1-2). The level of access is as follows: 1. Top position opens the upper door only. 2. Middle position locks both doors. 3. Bottom position opens both doors together. 1-2 BA430/BA440 Enclosure Maintenance Figure 1-2: Keylock Positions 1.3 Module Handles and Covers The BA400-series and the BA200-series enclosures provide front access to the CPU and memory and option modules, making it easier to access them. The two main differences between modules used in the BA200-series and the BA400-series enclosures and those used in other system enclosures are: · Modules that connect to external devices have bulkhead handles with the I/O connector on the handle. The handles replace the insert panels BA430/BA440 Enclosure Description 1-3 and internal cabling found in other enclosures. This design is easier to maintain since it eliminates problems caused by faulty internal cabling. · Modules that do not have external I/O connections have blank bulkhead covers. The module handles and blank covers form an electrical noise seal that complies with requirements for electromagnetic interference (EMI) by (1) keeping radio frequency interference generated by the system in the enclosure and (2) keeping external radio frequencies from entering the enclosure. The module handles and blank covers also help guarantee proper airflow. Each handle or cover has two captive quarter-turn Phillips screws to hold the module in the card cage. Module handles also use levers to help install or remove a module from the card cage. The five basic types of handles and covers or panels used for BA400-series compatible modules are: · Single-width flush handle · Single-width recessed handle · Single-width ratchet ejector handle (BA440 CPU and memory only) · Single-width blank cover · Double-width console panel (BA430 only) 1.3.1 Filler Panel Between Flush and Recessed Handles When you use a flush-handle module next to a recessed-handle module, you must install a metal filler panel (Figure 1-3) between the modules. Without the filler panel, circuitry on a flush-handle module adjacent to the recessed- handle module is exposed. The filler panel (70-24505-01) has four sets of finger stock that provide an effective chassis ground between the handles. Flush handles and covers have screw holes at the top and bottom of each side for the installation of this filler panel. Ratchet ejector handles are only used with some CPU and memory modules (Figure 1-3). To install a module with ratchet ejector handles, insert the module into the guide slot and position the ratchet ejector fingers into the latching slots at the top and bottom. Press the ratchet levers in until the module is seated in the backplane. Latch the ratchet ejectors when a positive feel of the bottom is realized. This removes any slack that may exist between the module fingers and the backplane. These handles are used to ensure a positive connection of the module in the backplane. 1-4 BA430/BA440 Enclosure Maintenance Figure 1-3: BA400-series Module Handles and Covers Some modules have special configurations, such as the BA440's H3604 console module, which is a hinged module cover that covers the CPU and four memory modules. The H3604 console module also provides an I/O connector for the CPU. Table 1-1 describes the common handle variations. BA430/BA440 Enclosure Description 1-5 Table 1-1: BA400-Series Module Handles and Cover Types ------------------------------------------------------------ Part Description ------------------------------------------------------------ Single-width blank cover Covers a standard Q22-bus module that does not have external I/O connectors (for example, a TQK70). If you install this type of cover next to a module with a recessed handle, you must add a metal filler panel to maintain FCC compliance. Single-width ratchet ejector handle The CPU module is equipped with ratchet ejector handles to keep the right amount of tension against the backplane connector. This ratchet arrangement causes the CPU and memory to make a tighter contact with the backplane bus and provides better system reliability. Single-width recessed handle The handle is riveted to the module. This style is the preferred handle for all BA200-series and BA400-series modules with external I/O connectors. The CXA16 and CXY08 communication modules use this type of handle. Single-width flush handle Used when a recessed handle would interfere with the module circuitry or I/O connector. The flush handle is also riveted to the module. Hinged console module (BA440 only) with I/O (H3604) The H3604 console module is a hinged I/O panel that covers the CPU module and four memory modules. NOTE: The H3604 console module interfaces with the CPU module through a short ribbon cable that connects the CPU and the H3604 console module. ------------------------------------------------------------ 1.4 Mass Storage Shelf The BA430/BA440 enclosure has a mass storage shelf that extends across the top of the enclosure. See Figure 1-4. The shelf may contain: · RZ-series ISEs · RF-series ISEs · TK-series tape drive · TLZ04 tape drive · System Control Panel (SCP) 1-6 BA430/BA440 Enclosure Maintenance Figure 1-4: BA430/BA440 Chassis and Mass Storage Area 1.5 RF-Series ISE An RF-series Integrated Storage Element (ISE) is a Digital Storage System Interconnect (DSSI) contains bracket/slides designed for mounting in the BA430/BA440 enclosure. The RF-series ISE has a front panel that contains controls and indicators Figure 1-5. As an example, three RF71s can be installed, giving the system a total disk capacity of 1.2 Gbytes (400 Mbytes each). Mass storage devices are mounted from the front of the enclosure with shock-mounting hardware. This shock-mounting hardware is different, depending on the type of device being used. Figure 1-6 shows the RF-series ISEs in the BA400-series where Bracket/ slides are mounted on the ISE for easier installation and removal. BA430/BA440 Enclosure Description 1-7 Figure 1-5: RF-series ISE Front Panel 1-8 BA430/BA440 Enclosure Maintenance Figure 1-6: Bracket Slides, used on BA430/BA440 Compatible ISEs 1.6 RZ-Series ISE An RZ-series ISE is a Small Computer System Intergration (SCSI) drive that is typically configured in the first three spaces on the left side of the mass storage area (Figure 1-7). NOTE: VAX 4000 systems do not support RZ-series ISEs. However, an RZ-series drive can be mounted in the space to the far right on the storage area and when a tape drive is not present in the system enclosure a spacer is used to fill the extra space. Bracket/slides are mounted on the ISE for easier installation and removal. BA430/BA440 Enclosure Description 1-9 Figure 1-7: RZ-series ISE Front Panel 1.7 Tape Drives Two types of tape drives are shown here and must be installed in the space on the far right of the storage area. 1.7.1 TK70 Tape Cartridge The top right compartment of the BA430 enclosure can contain an ISE (RF or RZ), a TK70 tape drive or an Rdat (TLZ04 controller) device. The TK70 tape drive holds one removable tape cartridge. The ISA can read data written on either a CompacTape II or CompacTape cartridge. You may use a CompacTape II or CompacTape cartridge as an input device to load software or data into your system. You should use a CompacTape II as an output device to make copies or backups of software or data. Section 3.6 shows an example of a TK70 tape ISE with controls and indicator lights labeled. 1-10 BA430/BA440 Enclosure Maintenance Figure 1-7: TK-series Tape Drive 1.7.2 TLZ04 Cassette Tape Drive The TLZ04 cassette tape drive can store up to 1.2 Gbytes of data on a TLZ04-CA cassette tape Figure 1-9. The TLZ04 tape drive is installed on the far right of the storage area. 1.8 System Control Panel (SCP) The BA430/BA440 SCP has the following indicators and buttons (Figure 1-10): · Temperature warning indicator · DC OK indicator · Halt button/indicator · Restart button/indicator BA430/BA440 Enclosure Description 1-11 Figure 1-9: TLZ04 Tape Drive Figure 1-10: SCP Identification NOTE: The board behind the system's SCP contains switches that can be set to off to prevent accidental activation of the Halt and Restart buttons. See Figure 1-11. 1-12 BA430/BA440 Enclosure Maintenance The temperature warning indicator shows that the system's internal temperature is approaching a level that may cause system components to overheat. If the internal temperature raises unacceptably, you will hear an audible pulsing sound and the temperature warning indicator will flash. The sound and visual marker are warning you of a possible temperature condition, before the system automatically shuts down. This feature allows you time to take corrective action. You could lower the room's temperature, remove airflow obstructions, or perform an orderly system shutdown to prevent data loss. The green DC OK indicator shows that the voltages are within the correct operating range. If the DC OK indicator is not lit when the system power is on, then a problem exists with the power supply. Below the DC ok indicator are the Halt and Restart button indicators. The Halt button is a two-position button. When pressed, the system halts and the Halt LED is lit as the console mode prompt (>>>) is displayed on the terminal screen. Before you can enter console commands, press the Halt button again to return it to the out position. Now you can enter console commands. If by mistake you press the Halt button, type C and press Return to continue. CAUTION: Pressing the Halt button halts the system unconditionally, in spite of setting the Break Enable/Disable switch on the console module. The Run/Restart button/indicator is located below the Halt button indicator. When pressed, the system returns to a run or reboot condition. If you have specified a device as the boot device and if the Break Enable/Disable switch is set to Disable, the system will reboot the system software. 1.9 Enclosure Modification A system manager may request the following modifications to the SCP and fan speed control. Switches located on the SCP board can be used to disable the SCP button functions. For example, if you were going to leave the access doors open when training new people on the system this could prevent accidental system shutdown. When a system is located in an area where fan noise is more tolerable to users, the speed of the fans can be increased. This action would take advantage of a potential increase in system reliability, because the system components function in a cooler environment. BA430/BA440 Enclosure Description 1-13 1.9.1 Halt and Restart Switch Disable There are four switches located on the top of the system control panel. These switches, when positioned off, disable the Halt and Restart button functions on the SCP. This could be used as a safety feature. When the upper door is open, these switches protect the system from accidentally being halted or restarted. Figure 1-11 shows the location of the switch pack, which allows the disabling of the SCP buttons. The factory configuration is always set to halt and restart enabled (switches on). Figure 1-11: SCP Enable/Disable Switch Location Switch position identifications are listed in Table 1-2. 1-14 BA430/BA440 Enclosure Maintenance Table 1-2: SCP Switches and Functions ------------------------------------------------------------ Switch State Function ------------------------------------------------------------ 1 --- Unused 2 on Halt Switch Enable 3 on Halt Indicator Enable 4 on Restart Switch Enable ------------------------------------------------------------ 1.10 Enclosure Card Cage The order of modules is different for the BA430 and the BA440 enclosures.

The I/O Panel contains two SCSI I/O connectors. The BA440 enclosure uses the hinged H3604 console module which is installed on hinge mounted over the CPU and the four memory modules Figure 1-13. 1.11.1 H3602 Console Module (Used in BA430) The H3602 console module is used on the BA430 enclosure system. This module covers two backplane slots (slot 2 and 3). Connect the console terminal and additional devices as follows: 1.11.2 H3604 Console Module (Used in BA440) \ Figure 1-13) The H3604 console module is a multifunction module that covers the CPU and memory locations (4) and is shown in Figure 1-13. The four memory modules occupy the first four slots on the right side, left of the memory modules is the CPU, which must occupy the fifth slot. The H3604 console module Figure 1-13 allows the CPU to interface to a serial line console device, a DSSI device, and to the Ethernet with the use of either a ThinWire BNC connector or a standard Ethernet 15-pin transceiver connector. The hinged H3604 console module has the following controls, ports, and indicators: · 100-pin CPU module interface connector · Baud rate select switch · Language inquiry switch · Hexadecimal display · Halt/Enable switch · Console serial MMJ connector · Ethernet selector switch · Ethernet port features · Standard Ethernet connector (15-pin) 1-16 BA430/BA440 Enclosure Maintenance Figure 1-12: H3602 CPU Cover and H3605 I/O panel (Used in BA430) · ThinWire Ethernet BNC connector · Standard/ThinWire select with indicator LEDs and switch · Fused current surge protection BA430/BA440 Enclosure Description 1-17 · Ethernet serial transceiver chip (SIA) · Daisy chain DSSI port · Two external (50-pin) Honda connectors (X = in/out, Y = in/out) · Two DSSI bus node ID select plugs · DSSI terminator (fuse protected) · -9 V DC/DC converter · TOY clock oscillator (25.6 Khz) · Ethernet selection LEDs (2) Figure 1-13: H3604 Console Module (Used in BA440) Figure 1-14 shows the location of the time of year (TOY) clock battery pack, fuses and power connector. 1-18 BA430/BA440 Enclosure Maintenance Figure 1-14: H3604 Rear View (Used in BA440) 1.12 Interface Module M9715-AA (Used in BA430) The M9715-AA interface module is located on the extreme right, next to the power supply (backplane slot 0). The M9715 I/O provides terminator power for both the DSSI and SCSI busses. Slot 0 is a dedicated dual C/D backplane slot on the Q22- bus (J24). 1.13 Power Supply (H7874) Both the BA430 and BA440 enclosures contain a modular H7874 power supply (Table 1-3). The power supply plugs into the backplane through two connectors. The H7874 power supply delivers the following maximum current: 22 amperes at +12.1 Vdc 60 amperes at +5 Vdc 7 amperes at +3.4 Vdc 4 amperes at -12.1 Vdc BA430/BA440 Enclosure Description 1-19 Figure 1-22: Power Supply Indicators The combined maximum current at +12.1 Vdc, -12.1 Vdc, +3.4 Vdc, and +5 Vdc must not consume more than 600 watts of power. See the configuration worksheet for details. Figure 1-22 for BA440 enclosure and Figure 1-22 for BA430 enclosure. Each mass storage device receives power through an 80-pin connector on the backplane located in back of each drive unit. Also, the H7874 power supply has an ac switch and three power controller I/O connectors for chained operation when used in a multienclosure configuration (Figure 3-22). 1-20 BA430/BA440 Enclosure Maintenance Table 1-3: H7874 Power Supply Switches, Controls, and Indicators ------------------------------------------------------------ Control/Indicator Function ------------------------------------------------------------ AC Present indicator (orange) Lights when the power switch is set to on (1), and the ac voltage is present at the input of the power supply. Power switch The power switch is used to turn system power on and off. The off position is indicated by a 0; the on position is indicated by a 1. The power switch also functions as the system circuit breaker. In the event of a power surge, the breaker will trip causing the power switch to return to the off posi- tion (0). Turning the system on resets the circuit breaker. If the circuit breaker trips, wait one minute before turning the system back on. DC OK indicator (green) When the DC OK indicator is lit, the voltages are within the correct operating range. An unlit DC OK indicator shows a problem with the power supply. Fan Failure indicator (amber) The Fan Failure indicator lights if either of the two cooling fans stops working. The power supply will automatically shut down the system as a precautionary measure when a fan failure is detected. Over Temperature indicator (am- ber) The Over Temperature indicator lights if the system has shut down due to an over temperature condition. Power bus connectors Three power bus connectors allow you to configure a power bus for systems expanded with a system expander. The power bus allows you to turn power on and off for the system through one power supply designated as the main power supply: this way, one power switch can control power for an expanded system (Figure 3-22). MO The main out connector sends the power control bus signal to the expander. One end of a power bus cable is connected here, the other end is connected to the SI (secondary in) connector of the expander power supply. SI The secondary in connector receives the power bus control signal from the main power supply. In a power bus with more than one expander, the power bus signal is passed along using the secondary in and out connectors. SO The secondary out connector sends the signal down the power bus for configurations of more than one expander. ------------------------------------------------------------ NOTE: The H7874 power supply automatically selects either 120 or 240 Vac when power is turned on. The power supply enters and completes a shutdown sequence whenever the BPOK H signal is negated. When BPOK H is asserted high on the Q22- bus, the power system is in a state to allow normal system operation. The following conditions negate BPOK H: BA430/BA440 Enclosure Description 1-21 · Temperature sensor triggered · An over current condition · An over voltage condition · Loss of ac input · Fan failure · Input voltage greater than 132 Vrms or less than 88 Vrms (if in 120 Vrms mode) or input voltage greater than 264 Vrms or less than 176 Vrms (if in 240 Vrms mode) 1.14 Fan Tray The BA430/BA440 enclosure has two 15-cm (6-in) dc fans (Figure 1-16) and Figure 1-17 below the card cage. The air is pulled in through the top slots of the enclosure and forced through the ISEs, power supply, and module options, and then expelled through the vents at the bottom of the enclosure. A temperature sensor in the power supply adjusts the volume of air by varying the fan's speed based on the system's temperature. The input voltage to the fans varies between 10 Vdc and 20 Vdc, depending on the internal temperature of the power supply. 1-22 BA430/BA440 Enclosure Maintenance Figure 1-16: BA430/BA440 Fan Tray Location BA430/BA440 Enclosure Description 1-23 Figure 1-17: Fan Tray Extended 1.14.1 Fan Speed Control Disable Some system managers request that the enclosure fans run at the maximum rate at all times, to take advantage of a potential increase in system reliability. The system environment must not exceed the limits described in the site preparation document. Figure 1-18 shows the location of the fan speed control (FSC) jumper. 1-24 BA430/BA440 Enclosure Maintenance Figure 1-18: FSC Jumper Location BA430/BA440 Enclosure Description 1-25 1.15 Backplanes Different backplanes are used in the BA430/BA440 Enclosures; backplane 54-20181-01 is used in the BA430 and backplane 54-19354-01 is used in the BA440 enclosure. 1.15.1 BA430 Backplane (54-20181-01) The BA430 backplane contains connectors for DSSI and SCSI busses. This 40.7 cm x 52.1 cm (16.0 inch x 20.5 inch) 4-layer backplane contains two signal layers, one power layer and one ground layer. Figure 1-19: BA430 Backplane 1.15.2 BA440 Backplane (54-19354-01) The BA440 enclosure has a 12-slot, quad-height backplane (Figure 1-20). The backplane is a 52.5 x 40.7-cm (21 x 16-in) assembly. The space between each backplane slot varies. The backplane's printed circuit board is an 8 layer, 2 sided etch board. From right to left, the first five backplane slots are for the memories and CPU, while the other seven slots are Q22/CD bus slots. The Q-bus can be extended using, an enclosure expander unit. The BA430/ BA440 enclosure supports 35 equivalent ac loads and 20 dc loads from all the modules installed in the backplane. An ac load is the amount of capacitance a module presents to a bus signal line. One ac load equals 1-26 BA430/BA440 Enclosure Maintenance 9.35 picofarads (pf). A dc load is the amount of dc leakage current a module presents to a bus signal line. One dc load is approximately 105 microamperes (µA). The backplane presents 4.0 ac loads to the Q22-bus. There are connectors provided for each of the following: · Fan tray · System control panel (SCP) · Four mass storage compartments · Power supply · Vterm regulator module Figure 1-20: BA440 Backplane 1.15.3 Configuration Guidelines Before changing the configuration of the BA430/BA440 enclosure, you must consider the following factors: 1.

You must leave at least 61 cm (24 in) of clearance in front of the system to access the doors and the system controls. You must also leave at least 5 cm (2 in) of clearance at the sides and rear for airflow. Since the base of the enclosure is 5 cm (2 in) wider than the cabinet in front and rear, you can place the rear of the system against a wall or table, and the system has enough space around it for adequate airflow. CAUTION: Due to the weight of the equipment, Digital recommends that at least two people to move system and terminal boxes. Installation 2-1 Figure 2-1: BA430/BA440 Enclosure Dimensions 2.1.2 Additional Equipment Make sure there is enough space for terminals and other peripheral equipment. When you plan the cable routing for multiterminal systems, consider factors such as safety, convenience, future expansion, and cost. Cabling should be in place and labeled after you install the system. 2.1.3 Static Electricity Static electricity can cause system failure and loss of data. To minimize static buildup, follow these guidelines: · Maintain relative humidity of at least 40%. · Place the system away from busy office corridors. · Avoid using carpeting in the computer area, if possible. If carpeting is to be installed, recommend antistatic carpeting. If carpeting is already in place, place an antistatic mat under the system. · Provide a separately fed electrical circuit for each enclosure ordered (whether an expander or system). 2-2 BA430/BA440 Enclosure Maintenance · Provide as many electrical outlets as are required for each additional device, such as any table top device and console terminal. 2.1.4 Acoustics The BA430/BA440 pedestal is designed for use in offices and other general working areas. The following acoustic emission and heat dissipation levels are for the BA430/BA440 pedestal. Levels may be lower, depending on the kind and number of mass storage devices in the system. Data is measured in accordance with ANSI S12.10-1985 (American National Standards Institute) and ISO/DIS 7779 (International Standards Organization). · LNPE (B) is the noise power emission level (A-weighted sound power level) measured in bels re 1 pw (reference 1 picowatt). LNPE for the BA430/BA440 enclosure is 5.8. · LPA is the sound pressure measured in decibels at 1.0 m from the front edge of the unit and 1.5 m above the floor.

Generally, you must set the baud rate of the console serial line to the same baud rate as the console terminal, and be sure the fixed disk drives are ready and not write protected. Refer to the system's operation manual for detailed instructions on setting these controls for the particular system you are installing. 2.4.5 Connecting the Power Cord Feed the power cord under the system from the rear and attach the power cord to the connector at the base of the power supply Figure 2-5. Plug the power cord into the wall outlet when all cabling has been installed. Figure 2-5: Connecting the Power Cable Installation 2-11 2.4.3 Installing RF- and RZ-Series ISEs NOTE: Expanded systems configured at the factory already have ISEs properly installed. CAUTION: Static electricity can damage integrated circuits. Use the wrist strap and antistatic mat found in the Antistatic Kit (part no. 29-26246) when you work with the internal parts of a computer system. Handle ISEs with care. Dropping or bumping the ISE can damage the disk surface. Carry or hold the ISEs by their metal brackets to avoid damaging the drive module. Install an ISE as follows: 1. Unpack the ISE. 2. Remove the blank ISE front panel from the expander. The front panels are each secured with one captive Phillips screw. 3. With the ISE controller module facing the right, slide the ISE along the guide rails into a mass storage cavity (Figure 2-6A). For single bus configurations, install ISEs in the upper mass storage area first; then install ISEs in the lower mass storage area. Always install ISEs working from right to left. NOTE: The first or rightmost mass storage cavity in the upper mass storage area is wider than the rest to accommodate a larger device. A small filler panel is used to fill the gap space when an RF- or RZ-series ISE is installed in this first cavity. 4. Using the upper and lower finger cutouts on the ISE bracketry, firmly push the ISE brackets until the interface card at the rear of the ISE plugs into its backplane connector (Figure 2-6A). Tighten the two captive screws. CAUTION: A small gap between the ISE mounting bracket tabs and the R400X frame is normal. Tighten the captive screws only until they are securely fastened. Do not try to force the tabs to fit flush against the frame. 5. Plug the remote front panel cable into the module inside the ISE front panel (Figure 2-6B). NOTE: The ISE front panel for RZ-series ISEs unlike the RF-series front panel has no buttons or indicators. 2-12 BA430/BA440 Enclosure Maintenance 6. Attach the ISE front panel to the enclosure by first fitting the panel's lower tabs and then fitting the panel into position. Secure the panel with its single screw (Figure 2-6C). 2.4.3.1 Inserting Bus Node ID Plugs Spare bus node ID plugs are supplied with your expander. The DSSI plugs for RF-series ISEs are dark gray (PN 12-28766-19). The SCSI plugs for RZ-series ISEs are lighter gray (PN 12-28766-28). Bus node ID plugs have prongs on the back that identify the bus node number (and by default, the unit number) of the ISEs to the system. Bus node ID plugs are shipped with the system and expander. To insert a bus node ID plug, align the two center prongs with the two center slots on the ISE front panel as shown in Figure 2-7. To remove a bus node ID plug, grasp it firmly and pull it straight out. Use the rules below for numbering bus node IDs for ISEs: · For each DSSI or SCSI bus, do not duplicate bus node numbers for storage elements. You can have only one storage element on bus 0 identified as bus node 0, one storage element as bus node 1, and so on; you can have only one storage element on bus 1 identified as bus node 0, one storage element as bus node 1, and so on. · By convention, the ISEs are numbered in increasing order from right to left starting with 0, and working from upper mass storage area to lower. Bus nodes 0-6 are typically used for storage devices, while node 7 is reserved for the adapter, and is the default bus node ID for the KZQSA and KFQSA adapters. NOTE: DSSI Bus node ID plugs are also used to supply node numbers for the two DSSI host adapters on VAX 4000 Model 300 systems. NOTE: If you change the bus node ID plugs while the system is operating, you must turn off the system and then turn it back on for the new plug positions to take effect. Installation 2-13 Figure 2-6: Installing an RF- or RZ-Series ISE 2-14 BA430/BA440 Enclosure Maintenance Figure 2-7: Inserting Bus Node ID Plugs 2.4.3.2 Labeling RF-Series ISEs for Systems with Multiple DSSI Busses VAX 4000 Model 300 systems have two separate DSSI adapters built into the CPU. Other systems may have more than one DSSI bus using the KFQSA storage adapter. Using R400X expanders you can fill up to four DSSI busses for a total of 28 RF-series ISEs. Each bus can have up to seven ISEs (bus nodes 0-6). When there are devices on more than one bus and the system's allocation class is not zero, you need to program new unit numbers for ISEs, as the unit numbers for ISEs throughout the system must be unique. Instructions provided in a later step describe how to program new unit numbers, overriding default values. With devices on two or more busses and a nonzero system allocation class, the ISE unit numbers will not match the bus node numbers on the bus node ID plugs. Unit number labels are provided with each ISE to identify unit numbers for the user. The labels stick onto the recessed label area on the ISE front panel as shown in Figure 2-11. Installation 2-15 2.4.8 Installing a TLZ04 Tape Drive NOTE: Expanded systems configured at the factory already have storage devices properly installed. CAUTION: Static electricity can damage integrated circuits. Use the wrist strap and antistatic mat found in the Antistatic Kit (part no. 29-26246) when you work with the internal parts of a computer system. Handle the TLZ04 tape drive with care. Dropping or bumping the drive can damage the product. Carry or hold the drive by its metal brackets to avoid damaging the drive. Install the TLZ04 Tape Drive as follows: 1. Unpack the tape drive. 2. Remove the blank front panel and filler panel from the upper right- most storage cavity of the expander. The front panel and filler panel are each secured with one captive Phillips screw. 3. With the drive positioned so that the Unload button and indicators are up, slide the drive along the guide rails into the upper right-most mass storage cavity (Figure 2-8A). 4. Using the upper and lower finger cutouts on the brackets, firmly push the drive brackets until the interface card at the rear of the drive plugs into its backplane connector (Figure 2-8A). Tighten the two captive screws. CAUTION: It is normal for there to be a small gap between the drive mounting bracket tabs and the R400X frame. Tighten the captive screws only until they are securely fastened. Do not try to force the tabs to fit flush against the frame. 5. Plug the ID cable into the connector inside the drive front panel ((tinsert)B). 6. Attach the drive front panel to the enclosure by first fitting the panel's lower tabs and then fitting the panel into position. Secure the panel with its single screw (Figure 2-8C). 2-16 BA430/BA440 Enclosure Maintenance Figure 2-8: Installing the TLZ04 Tape Drive 2.5.8.1 Inserting the TLZ04 Bus Node ID Plug Installation 2-17 The TLZ04 tape drive uses a SCSI bus node ID plug to identify the drive's node number to the system. Spare bus node ID plugs are supplies with your system and expander. SCSI plugs are light gray (PN 12-28766-28). To insert a bus node ID plug, align the two center prongs with the two center slots on the drive front panel as shown in Figure 2-9. To remove a bus node ID plug, grasp it firmly and pull it straight out. Use the rules below for numbering selecting an appropriate SCSI bus node ID for the TLZ04: · For each SCSI bus or KZQSA adapter, do not duplicate bus node numbers. If you are installing multiple TLZ04 or RZ-series ISEs, the SCSI bus node ID for each SCSI device must be unique. · By convention, the devices are numbered in increasing order from right to left starting with 0, and working from upper mass storage area to lower. Bus nodes 0-6 are typically used for storage devices, while node 7 is reserved for the SCSI adapter and is the default bus node ID for the KZQSA adapter. NOTE: If you change the bus node ID plugs while the system is operating, you must turn off the system and then turn it back on for the new plug positions to take effect. 2.6 Installing RF- and RZ-Series ISEs RF- and RZ-series ISEs are installed the same way. The RF-series ISE has a small flat cable which connects between the front panel and the CPU and a bus ID plug. The RZ-series ISE front panel has only an ID plug connected to it. No other controls or indicators are present on the RZ-series front panel. The RZ-series ISE is shown in Figure 2-10. When installing ISEs, you should first fill all of the available mass storage compartments in the system enclosure first then install other ISEs into the expander (if applicable). CAUTION: Static electricity can damage integrated circuits. Use the wrist strap and antistatic mat found in the Antistatic Kit (29-26246-00) when you work with the internal parts of a computer system. Handle RF-series ISEs with care. Dropping or bumping the ISE can damage the disk surface. 2-18 BA430/BA440 Enclosure Maintenance Figure 2-9: Inserting the TLZ04 Tape Drive Bus Node ID Plug Install an ISE as follows: 1.

The two DSSI host adapters. 2.5.2 Labeling RF-Series ISEs VAX 4000 systems have two separate DSSI adapters built into the CPU. Each bus can have up to seven ISEs (bus nodes 0-6). When devices are added to the second bus (bus 1) and the system's allocation class is not zero, you need to program new unit numbers for ISEs on one of the busses, as the unit numbers for ISEs throughout the system must be unique. When both DSSI busses have ISEs, and the system's allocation class is non- zero, the unit numbers for one of the busses will not match the bus node numbers on the bus node ID plugs. Unit number labels are provided with each ISE to identify unit numbers for the user. The labels stick onto the recessed label area on the ISE front panel as shown in Figure 2-12. 2-22 BA430/BA440 Enclosure Maintenance Figure 2-12: ISE Unit Number Labels 2.6 Installing a TL-Series Tape Drive The TL-series ISEs are installed the same as the RF-series ISEs. The ISE front panels have no cable connection to the ISE except for the ID plug. No other controls or indicators are present on the TL-series front panel. The TL-series ISE is shown in Figure 2-13. When installing ISEs, you should first fill all of the available mass storage compartments in the system enclosure first then install other ISEs into the expander (if applicable).
