There are two possible air flows for the fan unit. The air flow depends on the switch model. See
“Air Flow” on page 20 for an explanation of the model numbers and labels.
Figure 28: Air Flow Labels
To extract a Fan Unit:
1. Using two fingers, push both latch releases towards each other simultaneously while pulling
the fan module out of the switch. As the fan unseats, the fan status indicator will turn off.
1. Grasping the handle with your right hand, push the latch release with your thumb while pull-
ing the handle outward. As the fan unit unseats, the fan unit status indicators will turn off.
2. Remove the fan unit.
Figure 29: Fan Module Latches
To insert a FAN Unit:
1. Make sure the mating connector of the new unit is free of any dirt and/or obstacles.
Risk of Electric Shock!
With the fan module removed power pins are accessible within the module cavity.
DO NOT insert tools or body parts into the fan module cavity.
Operation without a fan unit should not exceed two minutes.
During fan hot-swap, if the LED indicator is OFF then the fan unit is disconnected.
Make sure that the fans have the air flow that matches the model number. An air flow
opposite to the switch design will cause the switch to operate at a higher (less than
optimal) temperature.
