Replace the expansion canister
7. To reinstall an expansion canister, or replace it with one from FRU stock, follow the procedure in
“Installing or replacing an expansion canister” on page 62.
Removing a fan module
You can remove a fan module from a 5U expansion enclosure.
Before you begin
Important: You can remove a fan module without powering off the expansion enclosure. However, to
maintain operating temperature, do not remove more than one fan module at a time.
• Remove a faulty fan module only when its replacement is ready to be installed.
• Do not remove a fan module from an operational enclosure for more than approximately 10 minutes.
The reduction in airflow through the enclosure might cause the enclosure or its components to shut
down to protect from overheating.
About this task
Note: If you plan to remove the expansion enclosure from the rack, you must remove all of the fan
modules.
Procedure
1. Identify the fan module to be replaced. When lit, the amber LED on the front of the fan module ( 1 in
Figure 98 on page 100) identifies a fault.
