Replacing the Fan Module

To replace a hot-swap fan module, complete the following steps:

1. Select an empty fan module bay on the rear of the switch. If the target bay is

covered by a blank fan filler plate, loosen the retainer screw and slide the filler

plate out of the slot.

2. Remove the new fan module from the antistatic shielded bag.

3. Slide the fan module into the card guides in the open slot and gently push it all

the way into the slot, so that it firmly engages with the connector (see the

illustration). Each fan module has a mechanical guide key to prevent you from

inserting the module incorrectly.

Retainer Screw

4. Tighten the retaining screw on the fan module. Torque the screw to

approximately 0.25 Nm +/- 0.1 Nm (2 inch-pounds).

5. Make sure that the fan module's LED is lit.

module and press Enter to reboot the switch.
