About the Drives

There are three types of drives that may be used in a drive module:
v 16-bit, 4.5 GB SCSI disk drives
v 16-bit, 9 GB SCSI disk drives
v 16-bit, 18 GB SCSI disk drives
The rackmount drive module supports up to ten drive FRUs. The status lights for all
drive FRUs are located on the front panel.

Front Panel

The front panel (Figure 73) contains the Drive LEDs that indicate the drive's status.
There are twenty LEDs on the drive modules's front panel (Figure 73), two above
each drive slot:
v Active LEDs, green lights that glow intermittently during SCSI activity to and
v Power/Fault LEDs, dual-color LEDs that (a) glow green when there is power to
from the drive and blink to identify the drive after the host issues a " Drive
Identify " command.
the drive, (b) glow amber when there is a drive failure.
