The power cord is included in the installation kit.

5.2.3 InfiniBand Cable Installation

All cables can be inserted or removed with the unit powered on. To insert a cable, press the con-

nector into the port receptacle until the connector is firmly seated. The orange LED indicator cor-

responding to each QSFP port will light when the physical connection is established (that is, when

the unit is powered on and a cable is plugged into the port with the other end of the connector

plugged into a functioning port). After plugging in a cable, lock the connector using the latching

mechanism particular to the cable vendor. When a logical connection is made the green light will

come on. When data is being transferred the light will blink green.

Figure 9: Top and Bottom Ports

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

LED indicator 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.

Caution: The switch platform will automatically power on when AC power is applied.

There is no power switch.

Caution: After inserting a power cable and confirming the green system status LED

light is on; make sure that the Fan Status indicator shows green.

If the fan status indicator is not green then unplug the power connection and call your

supplier.

Cables in the bottom row should be inserted up side down in relation to the how the

cables are inserted in the top row.
