Replacing an AT-CVFAN Module
This section provides instructions for replacing an AT-CVFAN fan module
if one fails.
Caution
For normal operation, the chassis must have two operational fans.

The AT-CVFAN modules are field-replaceable; however, they are
not hot-swappable. Therefore, make sure to power OFF the chassis
before installing the fan modules.

Be sure to observe all standard electrostatic discharge (ESD) pre-
cautions, such as wearing an antistatic wrist strap, to avoid
damaging the device. A fan module can be damaged by static
electricity.

Remove jewelry before replacing the fan modules.
Warning
Watch your fingers when handling the fan modules.
Warning
To avoid electric shock, do not touch the inside of the fan slots.
