Working With A Hard Disk Drive - IBM 8835 - Eserver 325 - 1 GB RAM Maintenance And Troubleshooting Manual

Working with a hard disk drive

This section describes the types of hard disk drives that the server supports and
other information that you must consider when installing a hard disk drive, as well
as how to install a hard disk drive in the server. Before you install a hard disk drive,
review the following information:
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

models of the server 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 attaches to connector J12 on the system board and
controls the SCSI IDs for the hot-swap drives.

SCSI ID 1.
