After plugging in a cable, lock the connector using the latching mechanism particular to the
cable vendor. When data is being transferred the Green LED will blink. See LED Interfaceunder
the Interfaces section.
Care should be taken as not to impede the air exhaust flow through the ventilation holes. Use
cable lengths which allow for routing horizontally around to the side of the chassis before
bending upward or downward in the rack.
To remove a cable, disengage the locks and slowly pull the connector away from the port
receptacle. LED indicator will turn off when the cable is unseated.
