Upgrading Your System 4-49
Installing a Hard Disk Drive
Use this procedure to add an optional hard disk drive to your system.
1. Observe the safety and ESD precautions listed at the beginning of this
chapter.
2. If tower-based system, unlock (if locked) the mechanical lock at the top of
the front door and open the door.
3. Power off the system. Ensure the power cords are unplugged from the AC
wall outlet.
4. Determine which hard disk drive bay will house the new hard drive, see
Figure 4-52.
In the BSU the hard disk drive bays consist of two slots for mounting the
hard drives. Confirm which slot of the hard disk drive bay the hard drive
will be mounted. The SCSI ID (0 and 1) is determined by the slot number
from left to right.
In the DEU the hard disk drive bays consist of eight slots for mounting the
hard drives. Confirm which slot of the hard disk drive bay the hard drive
will be mounted. The SCSI ID (0, 1, 2, 3, 8, 9, A, and B) is determined by
the slot number from left to right.
