D10 Service Position

To perform a removal or replacement procedure that requires access to the inside of the I/O subsystem,
the subsystem must be removed from the rack and placed on a stable work surface.
To put the drawer into the service position, do the following:
1. Shut down the system unit to which the I/O subsystem is connected.
2. From the rear of the rack, disconnect the I/O subsystem's power cables from the power distribution
bus.
3. Remove the retaining screws located on the rear of the I/O subsystem drawer.
4. Label and disconnect all of the cables connected to the rear of the I/O subsystem.
5. From the rear of the rack, pull the I/O subsystem straight back until the subsystem stops.
6. To allow the subsystem to move further to the rear, press the stop latch on the side of the enclosure.
7. Support the I/O subsystem as you pull it toward the rear of the rack.
8. When the I/O subsystem is out of the rack, place it on a stable work surface.

D10 Operating Position

To return the subsystem to the operating position, do the following:
1. From the rear of the rack, insert the I/O subsystem into the position from which it was removed. The
end of the I/O subsystem that has the power supplies goes toward the front of the rack.
2. Support the I/O subsystem as you push it toward the front of the rack.
3. Install the retaining screws in the rear of the I/O subsystem drawer.
4. Reconnect the cables to the rear of the I/O subsystem.
5. Reconnect the power cables.
6. Restart the system.

D10 Front Bezel

Before performing the following procedure, read the "Safety Notices" on page vii.
Removal
To remove the front bezel, do the following:
1. Open the front rack door.
2. Simultaneously press in both bezel-release tabs.
3. Pivoting the bezel from the top, swing the top forward.
4. Pull the bottom of the bezel up, then away from the subsystem chassis. This action releases the two
tab hooks located on the bottom of the I/O subsystem chassis.
Front Bezel Replacement
To replace the front bezel, do the following:
1. Open the front rack door.
2. Insert the two tabs located on the bottom edge of the bezel into their locking hooks, located on the
chassis.
3. Pivot the front bezel up toward the top of the chassis.
4. Align the release tabs to the matching slots located on the front of the subsystem chassis.
5. Gently push the tabs into the slots until the bezel seats against the front of the subsystem.
6. If the subsystem is not completely in the operating position, push the subsystem back into the
operating position as described in "D10 Operating Position."
7. Close the rack door.
