2.4 InfiniBand Cable Installation
All cables can be inserted or removed with the unit power on. To insert a cable, press the connector
into the port receptacle until the connector is firmly seated. The green LED indicator below each
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 a functioning port plugged into the other end of the connector).
After plugging in a cable, lock the connector using the latching mechanism particular to the cable
vendor. The yellow LED will light if the subnet manager is running (non blinking indicating that no
data is being transferred yet). When a logical connection is made the yellow LED will blink signi-
fying data is being transferred.
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 chassis.
Note: 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.
