Note: Cables in the bottom row should be inserted up side down in relation to the how the cables are
inserted in the top row.
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 holes 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
This switch can operate indefinitely with one of the three fans in the fan module inoperable so long as the
ambient temperature is below 45° Celsius.
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.
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.
