Installing a hard disk drive
The following notes describe the types of hard disk drives that your server supports
and other information that you must consider when installing a hard disk drive:
v The server supports two 25.4-mm (1-inch), slim, 3.5-inch hard disk drives. SCSI
v The SCSI server models support low voltage differential (LVD) hot-swap drives.
v A non-hot-swap hard disk drive does not require a backplane or tray and it does
v A non-hot-swap hard disk drive has a jumper block on the rear. Install a jumper
v If you install only one hard disk drive, for faster startup, install it in the primary
v If you are installing a hot-swap drive, continue with "Installing a hot-swap hard
server models come with a hot-swap SCSI backplane.
Each hot-swap drive is in a tray, which has a green activity LED and an amber
status LED in the upper-right corner. These LEDs are lit if the drive is active and,
in some cases, if the drive fails. Each hot-swap drive has a single-connector-
attached (SCA) connector, which is connected directly into the hot-swap SCSI
backplane. The backplane is attached to connector J12 on the system board and
controls the SCSI IDs for the hot-swap drives.
Note: The drive in bay 1 is assigned SCSI ID 0; the drive in bay 2 is assigned
SCSI ID 1.
not have indicator LEDs. However, you must attach the blue rails that come with
the drive before installing it in the server.
in the cable-selection position of the jumper block. For details, see the notes
under step 4 on page 17, and the documentation that comes with the drive.
startup device bay. For hot-swap SCSI drives, the drive in bay 1 is the primary
startup device. For SATA drives, the drive in bay 2 is the primary startup device.

a non-hot-swap hard disk drive" on page 17.
