Always store spare components in proper ESD containers when not in use.

The power supply and blower assembly may be replaced while the unit is running. (Refer to Hot Swap Operating Instructions on page 71)

Host interface cards and management cards may only be replaced when the Diamond Storage Array is off. Backup the unit fully before replacing these components.

You may remove a disk drive sled while the array is

powered on. Refer to the instructions in Hot Swap Operating Instructions on page 71 for details.

Exhibit 7-1: The management card may be accessed via a serial port DB-9 connector or an optional Ethernet connection.

3 Replace the disk drive sled with another sled.
