To remove, disengage the locks and slowly pull the connector away from the port receptacle. Both LED
indicators will turn off when the cable is unseated.
Care should be taken not to impede the air exhaust flow through the ventilation next to the InfiniBand ports.
Cable lengths should be used which allow for routing horizontally around to the side of the chassis before
bending upward or downward in the rack.
2.2.6 Extracting and Inserting the Fan Unit
To extract a Fan Unit:
1.
Loosen the two thumb screws locking the fan tray in place.
One of the fan status indicators (either green or yellow) will remain on.
2.
Pull the fan unit out by pulling on the thumbscrews. As the fan unseats, the fan status indicator
will turn off.
To insert a FAN Unit:
1.
Make sure the mating connector of the new unit is free of any dirt and/or obstacles.
2.
Insert the fan unit by sliding it into the opening until slight resistance is felt. Continue pressing
the fan unit until it seats completely.
3.
Turn the two thumb screws to lock the fan unit in place.
Note: The green fan status indicator should light and the yellow fan status should remain off. If not,
extract the fan unit and re-insert it. After two unsuccessful attempts to install the fan unit, power off the
switch before attempting any system debug.
Operation without a fan unit should not exceed one minute.
During fan hot-swap, if both indicators are OFF then the fan unit is disconnected.
