Maintenance
Replacing a Disk Drive
Caution: Drives and printed circuit board components
are sensitive to electrostatic discharge. To prevent
operating failure or damage, observe the following:
Establish a ground for yourself by using the wrist
grounding strap, or by touching the metal chassis prior
to handling or installing the drives or printed circuit
board components.
Note: There is no need to power OFF the DEU or the
computer system. The drives are hot swappable.
1
Unlock and open the door on the DEU cabinet.
2
Identify the failed drive using the Status LEDs and
the Fault LED.
3
Using your thumbs, apply a slight pressure outward
to release the drive latch clips, unlocking the failed
drive and remove the drive.
4
Remove your new disk drive from the shipping
carton and inspect the shipment. Remove the anti-
static protective packaging.
5
Holding the drive by its edges, locate the Drive
Latching Clips and pull out on the latches to unlock
them. The Drive Latching Clips are placed in the
locked position for shipping purposes.
6
Insert the drive into the drive bay by aligning its
rails into the drive bay slots, component side toward
the right (rack) or down (tower). Seat the drive by
applying light pressure with your thumb to the front
of the drive.

Press the Drive Latching Clips until they “snap” into
place.
