FRU Removal and Replacement
Removing a Redundant Fan Module
To remove a redundant fan module:
1. If the director is installed in a stand-alone configuration, go to step 2. If the
director is rack-mounted, unlock and open the cabinet rear door as directed by the
customer representative.
2. Follow ESD procedures by attaching a wrist strap to the director chassis and your
wrist, as shown in Figure 4–2.
CAUTION: To avoid causing machine errors or damage while working on the director,
follow ESD procedures by connecting a grounding cable to the director chassis and
wearing an ESD wrist strap.
3. Remove the RFI shield.
4. Identify the defective fan module from the amber LED on the module or failure
information at the HAFM server’s Hardware View.
5. Two captive screws secure the fan module (1) to the director chassis, as shown in
Figure 4–9. Using a standard flat-tip screwdriver, loosen the captive screws.

6. Using the rear of the fan module as a handle, pull the module from the director.
Support the fan module with one hand when performing this step.
CAUTION: Do not remove a fan module unless the replacement module is available.
Operation of the director with only one fan module for an extended period may cause
one or more thermal sensors to post event codes.
