Procedure
1. Disconnect the elbow of the lower cable management arm to swing it out of the way, as shown in
Figure 62 on page 63.
Follow the procedure that is described in “Moving the cable management arms” on page 79.
2. Carefully align the expansion canister with the expansion enclosure.
3. Rotate both the handles outward and insert the expansion canister into the disk enclosure.
4. When the expansion canister is fully inserted, rotate each handle inward to lock it into position, as

Installing or replacing a fan module
You can reinstall a fan module or replace a faulty fan module in a 5U expansion enclosure.
Before you begin
Important: You can replace a fan module without powering off the expansion enclosure. However, to
maintain operating temperature, replace the fan module within 10 minutes of its removal. When a fan
module is removed, the reduction in airflow through the enclosure might cause the enclosure or its
components to shut down to protect from overheating.
About this task
The expansion enclosure might or might not be powered on, depending on the number of fan modules
that need to be replaced. For example, the expansion enclosure must be powered off if all four fan
modules are removed.
This task assumes that the following condition was met:
• You removed a fan module, following the process described in “Removing a fan module” on page 99.
