6.2.2 Removing and Replacing the Fan Tray
If the fans are running too slowly or are no longer operational, the system management software
generates an alarm. You will need to replace the nonoperational fan tray. While you are replacing the
nonoperational fan tray, the operational fan tray continues to run. You can order a replacement fan tray
through Cisco.
The compartments for the two fan trays are located side by side near the bottom of the chassis, just above
the PEMs. A narrow bezel fits across the chassis to hold the air filters and fan trays in place (see
Figure
You need a Number 2 Phillips-head screwdriver to remove and replace the bezel and to tighten the screws
that secure the fan tray to the chassis.

if you are replacing an old filter with a new one.
Vacuum. Vacuum cleaning is preferred because you need not dry the filter afterwards. Vacuum the
filter until it is clean and free of dust.
Clean with plain water. Placing the filter under a stream of plain water is equally effective. Hold the
filter under the water with the metal grill facing up and let the water flow down through the filter.
(This orientation causes the water to flow through the filter in the direction opposite from the usual
air flow, so you dislodge rather than embed matter trapped in the filter.) Allow the filter to dry
thoroughly before reinstalling it.
Clean with hot water and mild detergent. If the filter is too dirty to be completely cleaned with a
vacuum or with plain water, immerse the filter in a solution of hot water and mild detergent. Rinse
the filter thoroughly in clear water and allow it to dry completely before reinstalling it.
The side with the metal grill is facing up.
One of the long sides goes in first.
