Installing and removing a fan module
CAUTION:
• For adequate heat dissipation, you must install five fan modules of the same model for the
switch.
• Make sure all slots have a module installed when the switch is operating.
• If more than one fan module fails during switch operation, do not remove the failed fan modules
simultaneously. Replace the fan modules one by one and finish replacing each fan module within
three minutes.
Installing a fan module
CAUTION:
To prevent damage to the fan module or the connectors on the backplane, insert the fan module
gently. If you encounter a hard resistance while inserting the fan module, pull out the fan module and
insert it again.
Select fan modules for the switch as needed. For the fan modules available for the switch and their
specifications, see
To install a fan module:
1.
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2.
Unpack the fan module and verify that the fan module model is correct.
3.
Orient the fan module with the "TOP" mark facing upward. Grasp the handle of the fan module
with one hand and support the fan module bottom with the other, and slide the fan module along
the guide rails into the slot until the fan module is fully seated in the slot and has a firm contact
with the backplane.

rotating.
