Before performing these procedures, read "Safety Notices" on page xi.
System Drawer Removal
CAUTION:
This unit weighs between 32 kg (70.5 pounds) and 55 kg (121.2 pounds). Three persons are
required to safely move it. Using fewer than three persons to move it can result in injury.
CAUTION:
v Removing the system drawer requires three people.
v Do not place more than one drawer in the service position at one time.
v Ensure that the system cables are not tangled and will not bind when placing the system drawer
into the service or operating positions.
To remove the system from the rack, do the following:
1. If you have not already done so, shut down the system as described in "Stopping the System without
an HMC Attached" on page 424.
2. Open the front and rear rack doors.
3. Disconnect all cables from the rear of the system drawer.
4. Disconnect the cable-management arm by pulling out the two captive snap buttons from the rear of
the system drawer.
5. From the front of the system drawer, lift the lower section of the system drawer release latches, which
are located on each side of the system drawer. The system drawer release latch clicks as it is put
into the release position.
6. Grasp the top section of both latches, and slowly pull the system drawer out into the service position.
7. Depress both safety release tabs located on each inner rail, and pull the system drawer out about 2
inches.
8. Put the system drawer into the service position.
9. Using three persons, grasp the system drawer handles located on each side of the system.
10. Depress the safety latches located on each rail.
11. Remove the system by pulling it completely out and away from the rack and outer rack rails.
12. Push the extended outer rails carefully back into the rack.
Note: There is a gravity-activated locking tab at the back of each extended outer rail. The locking tab
locks the outer rails into their fully extended position and is unlocked by the action of the inner
rail being pushed back into the rack. To compensate for the separation of the inner rail from
the outer rail, center the lock tab with your hand, then push the outer rail back into its retracted
position.
13. Close the front and rear rack doors.
