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 card 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 Green LED indicator 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
LED Operations
under the Interfaces section.
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
LED
Operations
under the Interfaces section.
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. The LED indicator will turn off when the cable is unseated.
