Installing a SCSI Hard Drive

drive in the hot-docking bay. Each LED corresponds directly to a drive, so that the right
most LED shows activity in the right most drive. The LEDs and corresponding drives are
numbered (left to right) zero to four. When a yellow LED for a hard drive is on
continuously, you are permitted to hot-swap (replace) a bad drive with a good one. If the
operating system installed supports hot-swapping hard drives, the system does not need
to be powered off.
To install a SCSI hard drive, perform the following steps:
1. Open the front bezel door by simultaneously pulling on the raised lip of the front
bezel door and putting counter pressure on the bezel latch area. See Figure 4-2 on
page 81 for an illustration of the procedure.
2. Position the new carrier and drive assembly so that it engages the bay guide rails.
3. Gently push the drive into the bay. Swing the locking handle towards the chassis.

Hot-Plug PCI Add-In Boards
The SGI 1450 server supports six hot-plug PCI add-in boards. The six slot openings (seen
from the back of the system) are shown in Figure 1-7 on page 13.
Each hot-plug PCI add-in board is held in place by a PCI Hot-Plug (PHP) Retention
mechanism (see Figure 4-4).
Note: At this time, the Linux operating system does not support use of the PCI Hot-Plug
(PHP) feature. If you are running Linux, your system must be turned off before installing
or removing PCI boards. Windows 2000 requires drivers that are PHP compatible in
order to use the PHP feature.
