Replacing a controller fan module

Procedures for the removal and installation of controller fan modules.

This section provides procedures for replacing a failed controller fan module. Illustrations in controller fan replacement procedures show top panel views of the enclosure, with the fan properly oriented for insertion into the top panel of the enclosure, near the IOMs. Remove the top lid “B”to access the controller module fan. See Figure 1. Reattach top lid “B”when you complete the procedure

If a system fan module fails, the remaining fan is sufficient to maintain operation of the enclosure. You need not halt operations and completely power-off the enclosure when replacing only one controller module fan.

CAUTION:

Do not remove the cover from the controller fan module due to danger from electric shock inside. Return the module to your supplier for repair.

See CAUTION bullets regarding electrostatic discharge and anti-static protection in the ESD precautions section.

Tip: The illustrations show controller fan module replacement as you face the enclosure front and view the top panel. See also Figure 3 and Figure 1.
