2.2.5 InfiniBand Cable Installation
All cables can be inserted or removed with the unit powered on. To insert a cable, press the connector into
the port receptacle until the connector is firmly seated. The GREEN LED indicator, below 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 con-
nection is made the yellow light will come on. When data is being transferred the yellow light will blink.
Cables in the bottom row should be inserted up side down in relation to the how the cables are inserted in
tehtop row.
