Preparation 1-5

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 airflow. See Figure 1-2.

Figure 1-2

PIU Rear Panel
Arrow should point toward blower.

BXB-0387A-92

1-6 Preparation

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 1-3).

Remove and reposition the rear panel.

Install the 12 Phillips screws.

Line up the rollers at the top of each side of the PIU enclosure with
the slides in the cabinet. See Figure 2-2. Push the PIU enclosure
straight into the cabinet until it seats.
Install the two Phillips screws at the bottom of the PIU enclosure
(see 1 ).
Tighten the top two captive screws (see 2 ).

Installing the BA655 PIU Option 2-5

2.3 Cable the BA655 PIU

Acceptance and Troubleshooting 3-1

3.1 Restore Power and Check Self-Test Results
Power up the system and check the self-test display to see if the
KZMSA adapter passed self-test. You can also check the yellow
LED on the KZMSA adapter. The LED is on if the adapter passes
self-test. See Section 3.2 for more information on testing.

Close the cabinet doors.

Pull the AC power circuit breaker handle up to turn the circuit
breaker on.

Turn the control panel keyswitch to the Enable position; the system
should power up and run self-test.

In Example 3-1:
1

Self-test runs at power-up.

The user enters a show config command.

The first KZMSA adapter, kzmsa0, passes self-test. Kzmsa0 supports
the in-cabinet RRD42 CD drive.
The second KZMSA adapter, kzmsa1, also passes self-test. This
adapter supports the devices in the SCSI PIU.
The user enters a show device kzmsa1 command. You can check to
see if all the devices associated with the KZMSA adapter are reported
by issuing this command.
