To obtain the list of supported Mellanox cables for your adapter, please refer to
the Cables Reference Table at
http://www.mellanox.com/products/interconnect/cables-
configurator.php .
3.7.1 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.
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.
NOTE:
When installing cables make sure that the latches engage.
WARNING: Always install and remove cables by pushing or pulling the cable and
connector in a straight line with the card.
•
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 Interface under the Interfaces section.
•
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.
