D20 Service Position - IBM pSeries 7311 D10 Service Manual

D20 Service Position

Attention: When placing your Model D20 subsystem into the service position, all stability plates must be
firmly in position to prevent the rack from toppling. Ensure that only one system drawer is in the service
position at a time.
Before doing any service actions inside your Model D20 subsystem, put the Model D20 subsystem into the
service position.
To place the drawer into the service position, do the following:
1. Open the front rack door.
2. If your Model D20 subsystem is equipped with two blue thumbscrews securing it to the rack, remove
the thumbscrews at this time. The screws are located on the bezel, just above each subsystem release
latch.
3. Release the subsystem release latches located on the left and right side.
4. Pull the system drawer out from the rack until the rails are fully extended.
Note: When the system rails are fully extended, safety latches on the slide rails lock into place. This
action prevents the system from being accidentally pulled out too far and dropped. The following
illustration shows a system drawer in the service position.
