Cable Installation
1. All cables can be inserted or removed with the unit powered on.
2. To insert a cable, press the connector into the port receptacle until the connector is firmly
seated.
a. Support the weight of the cable before connecting the cable to the adapter card. Do this by using a cable
holder or tying the cable to the rack.
b. Determine the correct orientation of the connector to the adaptercard before inserting the connector. Do not
try and insert the connector upside down. This may damage the adapter card.
c. Insert the connector into the adapter card. Be careful to insert the connector straight into the cage. Do not
apply any torque, up or down, to the connector cage in the adapter card.
d. Make sure that the connector locks in place.
3. After inserting a cable into a port, the Yellow LED indicator on 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). See
“Adapter Card LED Operations,” on page 40
.
4. 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
“Adapter Card LED Operations,” on page 40
.
5. 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.
6. 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.
