Instruction manual

Before Adding a Disk Drive Module
1. Identify the slot for the new disk drive module by using the configuration planning
information for your system. A dummy disk drive module should be in the slot. Refer
to Figure 18.
Use the SCSI Device Identification and Removal service aid to set the disk drive
slot to Insert. If you then remove the dummy disk drive module from the identified
slot, an amber light on the backplane should be visible. This verifies that you have
selected the correct slot into which to add the new disk drive module. This light
goes off when a disk drive module is added. If it does not, it is visible as the amber
Check light on the disk drive module that you have added.
