Basic Operation and Installation

Cables in the bottom row should be inserted up side down in relation to the how the cables are inserted in the top row.

Figure 30: Top and Bottom Ports

To remove, disengage the locks and slowly pull the connector away from the port receptacle. The

LED indicator for that port will turn off when the cable is unseated.

Care should be taken not to impede the air flow through the ventilation holes next to the connector 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.

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.

Operation without a fan unit should not exceed two minutes.

During fan hot-swap, if both indicators are OFF then the fan unit is disconnected.

There are two possible air flows for the fan unit. The air flow depends on the switch model. See

“Air Flow” on page 22 for an explanation of the model numbers and labels.

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.
