HP 4400 Enterprise Virtual Array Expansion Rack Reference Guide (5697-2285, January 2013)

Inspect expansion rack disk drives
After the expansion rack is powered up, ensure that all disk drives are fully engaged and seated
in their associated enclosures. Observe the disk drive status indicators to ensure that the disks are
working properly. The status indicators will be amber or blue depending on the condition of the
disk enclosure. See Figure 18 (page 15) for the location of the disk drive indicators and
Table 2 (page 15) for a description of the indicators.

Inspect the disk enclosure power supplies
From the rear of the expansion rack, observe each power supply. Each disk enclosure has two
power supplies. Each power supply has one green LED on its fan casing. Make sure the green
light on each power supply is on and not flashing. If not, diagnose and correct the problem before
proceeding with the next steps.
