v If the server will be configured for RAID operation, see the documentation that
comes with the controller for instructions for installing a hard disk drive.
v All hot-swap drives in the server should have the same throughput speed rating;
using drives with different speed ratings might cause all drives to operate at the
lowest throughput speed.
v To minimize the possibility of damage to the hard disk drives when you install the
server in a rack configuration, install the server in the rack before you install the
hard disk drives.
v You do not have to turn off the server to install hot-swap drives in the hot-swap
drive bays. However, you must turn off the server when you perform any steps
that involve installing or removing cables.
v Some filler panels come with slim fillers.
The following illustration shows how to install a hot-swap hard disk drive.

To install a hot-swap hard disk drive, complete the following steps:
1. Read the safety information that begins on page v and "Installation guidelines"
on page 26.
2. Remove the filler panel from one of the empty hot-swap bays.
3. Touch the static-protective package that contains the hard disk drive to any
unpainted surface on the outside of the server; then, remove the hard disk drive
from the package.
4. Make sure that the tray handle is open; then, install the hard disk drive into the
hot-swap bay.
Note: When you turn on the server, check the hard disk drive status LEDs to make
sure that the hard disk drive is operating correctly. If the amber hard disk drive
status LED for a drive is lit continuously, that drive is faulty and must be replaced. If
the green hard disk drive activity LED is flashing, the drive is being accessed.
If you have other devices to install or remove, do so now. Otherwise, go to
"Completing the installation" on page 50.
