Fans
The fans are hot pluggable. This means you can remove or install one of the fans
while the switch is operating without disrupting service. The fan is completely
enclosed, so there is no risk of injury from the fan blades. The fans are also
interchangeable; that is, any fan will fit in any bay. Before removing a fan, connect
an ESD wrist strap to a ground point on the chassis or rack.
6.6.1
Removing a Fan
To remove a fan, loosen the two captive screws shown in Figure 6-8 with a flat-
blade screw driver. Grasp the fan by the screws and pull firmly to disengage the
fan from the backplane connector. Slide the fan out of the chassis.

WARNING!! Voltage is present in an open bay when the switch is operating. To
avoid personal injury, do not place hands or objects into an open
bay.
CAUTION!
Replacement fans must be compatible with the switch air flow
direction of the other fans. Installing a fan with an opposing air
flow direction could lead to an over temperature condition.
To avoid overheating, do not operate the switch without a fan any
longer than it takes to install a new fan.
