Note to expansion unit users: The
instructions in this procedure are written
based on the rack model. Tower users may
still use this procedure. However, expansion
unit users should ignore specific references to
rack-only features such as rack doors, rack
thumbscrews, rack-specific FRU orientation,
and so on.
1.
Open the front rack door.
2.
Remove the two thumbscrews
(A)
that
secure the system unit (B) to the rack.
3. Push the cover release latches (C) in the
direction of the arrows to release the cover
from the system unit.
4. Pull the cover out and away from the
system unit.
2. Determine if repair can continue concurrently

concurrently. If the top LED is green as shown
in the graphic on the right, you may proceed
with a concurrent repair. Otherwise, the repair
can continue only after powering off the unit.
If the unit is already powered off, you may
proceed with a nonconcurrent repair.
3.
Select an action:
Nonconcurrent repair.
Power off the unit and
continue the repair. Concurrent repair.
Continue the repair
with unit power on. Delay the repair.
