installing new drives, remove the filler panels and save them for future use.
Each of the 14 bays must contain either a filler panel or a hard disk drive.
Hard disk drives
You can install only slim Ultra320 hot-swap hard disk drives in the
expansion unit.
Replacing a hot-swap hard disk drive
Hard disk drive problems include any malfunctions that delay, interrupt, or prevent
successful I/O activity between the hosts and the hard disk drives in the expansion
unit. This includes transmission problems between the host controllers, the ESMs,
and the drives. This section explains how to replace a failed drive.
Attention: Failure to replace a hard disk drive in the correct bay might result in
loss of data. If you have data stored on the hard disk drive, label the drive before
you remove it. Then, when you replace the drive, install it in the same drive bay
from which you removed it.
Check the hardware and software documentation provided with your server to see if
there are restrictions regarding hard disk drive configurations. Some system SCSI
configurations might not allow mixing different hard disk drive capacities or types
within an array.
Complete the following steps to replace a hot-swap hard disk drive:
1. Read the instructions that come with the hard disk drive.
2. Read the “Installation guidelines” on page 23 and the safety information
beginning on page 37.

Attention: Never hot-swap a hard disk drive when its green activity LED is
flashing. Hot-swap a drive only when its amber status LED is lit (not flashing) or
when the drive is inactive (activity LED is off).
