4.4.1 Optical Modules for QSFP
These cards support optical modules for active fiber optical cables. The part ordering number for
this module is MFM4R12C-QDR.
4.4.2 Modules for QSFP to SFP+
These cards support modules for SFP+ cables. The Quad to Single Small Form Factor Pluggable
adapter (QSFP to SFP+ adapter or QSA) is built in QSFP form factor with a receptacle for SFP+
cable connector. To order these adapters contact your authorized Mellanox Representative.
4.4.3 Cable Installation
All cables can be inserted or removed with the unit powered on. To insert a cable, press the con-
nector into the port receptacle until the connector is firmly seated. 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). After
plugging in a cable, lock the connector using the latching mechanism particular to the cable ven-
dor. When a logical connection is made the YELLOW LED will come on. When data is being
transferred the yellow led will blink.
Care should be taken not to impede the air exhaust flow through the ventilation holes. Cable
lengths should be used which allow for routing horizontally around to the side of the chassis before
bending upward or downward in the rack.
When installing cables make sure that the latches engage.
Always install and remove cables by pushing or pulling the cable and connector in a
straight line with the card.
