1. Check the Fan Status LED, a red LED indicates the fan has failed and needs to be replaced, an amber LED
indicates a problem. See “Cooling Unit LED indicates a problem with the fan” on page 542
2. Use a No. 1 Phillips screwdriver to turn each set screw counter-clockwise to loosen them. The screws
remain attached to the Cooling Unit so they will not be lost.
3. Pull the detached Cooling Unit out of the subsystem enclosure. You can grasp the posts that house the

1. Align the fresh Cooling Unit to be received in the empty cooling unit bay of the subsystem enclosure.
2. Slide the Cooling Unit into place until the set screws are able to be reattached to the backplane of the
enclosure.
3. Turn the set screws to tighten them.
4. Check the Fan Status LED on the Cooling Unit to make sure it is green (functioning properly).
Important
In the event of a Cooling Unit failure, DO NOT remove the failed unit until
there is a replacement available and on hand. A single functioning Cooling Unit
is adequate for cooling the system as long as the failed Cooling Unit remains in
place. Removing the failed unit without replacing it will adversely affect airflow
within the enclosure resulting in critical overheating and shutdown of the
enclosure.
