How to Install the Disk Cage Assembly
What to Do
1. Lift the disk cage assembly into the side of the chassis.
Orient the disk cage so that the open drive bays are facing the front of the chassis.
Grasp the free end of the LED ribbon cable (from the LED/keyswitch assembly)
and pull it out the front of the disk bay opening to make room for the disk cage.
2. Align the screw holes on top of the cage with the captive screws in the upper
part of the chassis.
3. From the top of the chassis, use a long flat-blade screwdriver to partially
tighten the two captive screws that secure the disk cage to the chassis.
Insert the screwdriver through the two access holes on top of the chassis to
tighten the screws. Before tightening the screws fully, ensure that the two bottom
screws are fully tightened (see Step 5). Finish tightening the top two screws only
after the bottom screws are tightened.
Caution - Take care to avoid damaging any cables that may be located near the
captive screws.
4. Carefully lower the chassis onto its closed side.
Enlist the help of another person to accomplish this safely.
Do not lift the chassis using the plastic panels at the front or the side of the
chassis.
Roll the system onto a solid surface that spaces the unit about 2 inches (5 cm) off
the floor; for example, use a pair of wooden boards. Do not allow any of the
weight to rest on the plastic panels at the front of the chassis.
5. From the underside of the chassis, use a large flat-blade screwdriver to tighten
the two captive screws that secure the disk cage to the bottom of the chassis.
