Preparing the Expansion Cabinet and
Drive Trays
This section describes the tasks for preparing the expansion cabinet and disk drive
trays for the controller module installation.

To Prepare the Expansion Cabinet

Refer to the documentation that came with your expansion cabinet for information
on how to perform the following tasks:
1. Remove the external covers from the cabinet—front, back, sides, and
kick panel.
2. Power off the expansion cabinet.

To Set the Drive Tray and SEN Card SCSI IDs

Tools: None
Equipment: Jumpers (supplied on I/O board), antistatic wrist strap
Each drive tray contains an I/O board that determines the SCSI target addresses for
the drives. The controller module requires drive SCSI ID settings of 8 through 14.
New drive trays are shipped from the factory with the 8 through 14 SCSI IDs preset.
If you are connecting existing drive trays to the controller module, you must verify
that the drive tray SCSI ID settings are correct. If not, you must change them.
Caution – Electrostatic charges can damage sensitive components. Use a grounding
wrist strap or other antistatic precautions before removing or handling the I/O
boards.
1. Put on an antistatic wrist strap.
2. Beginning with the top or bottom drive tray, loosen the two thumbscrews on the
back left side (connector side) of the tray (
3. Pull the I/O board out of the drive tray with your left hand (
If necessary, use the thumbscrews to pull the I/O board out far enough so that you
can grip the outer casing with your left hand. Remove the I/O board from the drive
tray.
