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.
