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, the left and right fans are the same unit.

To remove a fan, loosen the two retaining screws, then grasp the fan housing and 
pull firmly to disengage the modular connector. Slide the fan out of its bay as 
shown in 

.

When replacing a fan, consider the following:

„

The left and right fans are interchangeable. However, you must orient the 
fan so that the modular connector aligns with the mating connector in the 
switch as shown in 

„

Replacement fans must be compatible with the switch air flow direction. Air 
flow direction for switch model SB2A-16A is front-to-back; air flow direction 
for switch model SB2A-16B is back-to-front.

„

A label on the fan indicates the switch model number and fan air flow 
direction as shown in 

Both fans must have the same air flow direction to prevent the 
switch from overheating.
