4: Internal Component Replacement and Upgrades
Drive Bay Installation/Removal
Hard Disk Drives: Because of their hot-swap capability, you do not need to access the inside of
the chassis or power down the system to install or replace SATA drives. Proceed to the next step
for instructions. Note that the operating system you use must have RAID support to enable the
hot-swap capability of the SATA/SAS drives.
Use caution when working around the disk drive backplane. Do not touch the backplane with any
metal objects and make sure no cables touch the backplane. Also, regardless of how many drives
are installed, all four drive carriers must remain in the chassis to maintain proper airflow.
Disk Drive Removal and Installation
The system disk drives are mounted in drive carriers to simplify their installation and removal
from the chassis. These carriers also help promote proper airflow for the system. For this reason,
even empty carriers without drives installed must remain in the chassis.
Mounting a Drive in a Carrier
Check with your SGI sales or service representative to obtain new or replacement hard disk drives
for the server.
Install the drive into the carrier with the printed circuit board side facing down so that the
mounting holes align with those in the carrier.
Secure the drive to the carrier with four screws, as shown in Figure 4-2.
