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, corresponding 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 yellow light will come on. When data is being transferred the yellow light
will blink.
