Document Structure This manual uses a structured documentation design. Topics are organ­ ized into small sections for efficient on­line and printed reference. Each topic begins with an abstract. You can quickly gain a comprehensive over­ view by reading only the abstracts. Next is an illustration or example, which also provides quick reference. Last in the structure are descriptive text and syntax definitions. This manual has three chapters as follows: · Chapter 1, Preparation, gives an overview of the option and tells how to prepare for the installation. · Chapter 2, Installing the BA655 PIU Option, gives instructions on how to install and cable the BA655 PIU. · Chapter 3, Acceptance and Troubleshooting, describes the accep­ tance procedure. vi Conventions Used in This Document Book titles.

Sections in this chapter include: · BA655 Disk and Tape PIU Description · Prepare Area, Kit, and Tools · Check PIU Enclosure for Proper Airflow 1­2 Preparation 1.1 BA655 Disk and Tape PIU Description The BA655 PIU can be installed to provide additional I/O. This op­ tion includes the enclosure, two modular expansion shelves, and two power supplies. The KZMSA adapter, storage units, and SCSI cables must be ordered separately. Figure 1­1 BA655 PIU Preparation 1­3 Before installing additional SCSI I/O in your system, you must order the KZMSA­AB option which includes the KZMSA adapter and the KZMSA Adapter Installation Guide. SCSI storage devices and cables must also be ordered separately. Table 1­1 lists the storage devices, and Table 1­2 lists the cables. Table 1­1 SCSI Storage Device Options Table 1­2 SCSI Cable Options Option Number Item RZ26­VA 3.5 inch SCSI disk drive (1 Gbyte) RZ73­VA 5.25 inch SCSI disk drive (2 Gbytes) TLZ06­VA 3.5 inch tape drive (4 Gbytes) Option Number Item BC10U­06 6 ft SCSI internal cable (17­03153­02) BC10U­09 9 ft SCSI external cable (17­03153­03) 1­4 Preparation 1.2 Prepare Area, Kit, and Tools Set up a work space near the system where you can store compo­ nents while you work on the BA655 option installation. Unpack the BA655 option kit and check the contents against Table 1­3. Pre­ pare the system for shutdown. You will need a Phillips head screwdriver.

Prepare an area near the system where you can place system compo­ nents during the installation. 2. Perform an orderly shutdown of the system. 3. Turn the control panel keyswitch to the Disable position. 4. Open the cabinet doors. 5. Push the AC power circuit breaker handle down to shut the circuit breaker off. 1­6 Preparation 1.3 Check PIU Enclosure for Proper Airflow When installing a BA655 PIU in the cabinet, make sure that the rear panel arrow points toward the blower to permit proper air­ flow. See Figure 1­2. Figure 1­2 PIU Rear Panel Preparation 1­7 The arrow on the rear panel of the PIU enclosure must point toward the blower. That is, the arrow must point up when installing the PIU below the blower; it must point down when installing the PIU above the blower. If necessary, use the following procedure to reinstall the PIU rear panel: 1. Using a Phillips screwdriver, remove the 12 screws on the rear panel (see 1 in Figure 1­3). 2. Remove and reposition the rear panel. 3. Install the 12 Phillips screws. Figure 1­3 Rear Panel Removal Installing the BA655 PIU Option 2­1 Chapter 2 Installing the BA655 PIU Option This chapter describes the installation of the BA655 PIU option into an H9F00­Ax system cabinet or an H9F00­Bx expander cabinet. Sections in­ clude: · Remove the Cabinet Airflow Plate · Install the BA655 PIU · Cable the BA655 PIU · Install the Disk or Tape Devices 2­2 Installing the BA655 PIU Option 2.1 Remove the Cabinet Airflow Plate Remove the cabinet airflow plate located below the blower in the disk PIU space. The plate blocks airflow when a PIU is not pre­ sent. Figure 2­1 Airflow Plate Installing the BA655 PIU Option 2­3 1. Open the front cabinet door. 2. Using a Phillips screwdriver, remove the two screws (see 1 in Figure 2­1) and slide the airflow plate out of the cabinet. 2­4 Installing the BA655 PIU Option 2.2 Install the BA655 PIU Insert the BA655 PIU into the cabinet. Figure 2­2 Installing the BA655 Option Installing the BA655 PIU Option 2­5 1. Line up the rollers at the top of each side of the PIU enclosure with the slides in the cabinet. See Figure 2­2. Push the PIU enclosure straight into the cabinet until it seats. 2. Install the two Phillips screws at the bottom of the PIU enclosure (see 1 ). 3. Tighten the top two captive screws (see 2 ). 2­6 Installing the BA655 PIU Option 2.3 Cable the BA655 PIU Connect the SCSI cable to the leftmost connector in the modular expansion shelf. Thread the cable through the opening on the side of the cabinet. Connect the other end of the cable to the I/O bulk­ head. See Figure 2­3. Figure 2­3 Cabling Installing the BA655 PIU Option 2­7 Use the following procedure to cable the SCSI disk PIU. 1. Connect the BC10U­xx cable to the leftmost connector on the SCSI shelf. 2. Thread the cable through the opening at the side of the cabinet. 3. Connect the cable to the I/O bulkhead panel reserved for the SCSI I/O. See the KZMSA Adapter Installation Guide for more information. NOTE: When both shelves of devices are on one SCSI bus, you must cable the two shelves together with a BC10U­06 cable. Plug the cable into the rightmost connector of each shelf. 2­8 Installing the BA655 PIU Option 2.4 Install the Disk or Tape Devices Insert the storage devices into the modular expansion shelves. Figure 2­4 Sample SCSI Configuration Installing the BA655 PIU Option 2­9 Figure 2­4 shows a SCSI PIU with two modular expansion shelves. Shelf 1 contains seven 3.5 inch disk drives, and shelf 2 contains two 5.25 disk drives. Each 3.5 inch disk drive uses one slot; each 5.25 inch disk drive uses three slots. A tape drive uses one slot. To install a storage device: 1. Insert the storage device in the slot guides. 2. Push it in until the mounting tabs lock in place (see Figure 2­5). Figure 2­5 Storage Device Mounting Tabs BA655 SCSI Disk and Tape PIU Configuration Rules · The maximum number of SCSI disk and tape PIUs is two in a main cabinet and four in an expander cabinet. · Each SCSI disk and tape PIU contains two shelves. Each shelf con­ tains seven slots for disks and tapes, in any combination. Acceptance and Troubleshooting 3­1 Chapter 3 Acceptance and Troubleshooting This chapter discusses the acceptance procedure and troubleshooting guidelines for the BA655 option. See the Advanced Troubleshooting man­ ual for more information on troubleshooting. Sections include: · Restore Power and Check Self­Test Results · Testing the KZMSA Adapter and SCSI Devices · SCSI Device LEDs 3­2 Acceptance and Troubleshooting 3.1 Restore Power and Check Self­Test Results Power up the system and check the self­test display to see if the KZMSA adapter passed self­test. You can also check the yellow LED on the KZMSA adapter. The LED is on if the adapter passes self­test. See Section 3.2 for more information on testing.
