LED Interface
There are two I/O LEDs per port:
LED 1
: A bi-color I/O LED which indicates link status. LED behavior is described below for
Ethernet and InfiniBand port configurations.
LED 2
: Reserved for future use.
LED1 Link Status Indications (Physical and Logical) - Ethernet Protocol:
LED Color and State
Description
Off
A link has not been established
Blinking Amber
a
1 Hz Blinking Amber occurs due to running a beacon command for locating the adapter
card.
4 Hz blinking Amber indicates a problem with the link
Solid Green
Indicates a valid link with no active traffic
Blinking Green
Indicates a valid logical link with active traffic
a
1 Hz Blinking Amber occurs due to running a beacon command for locating the adapter card.
LED2 Link Status Indications (Physical and Logical) - InfiniBand Protocol:
LED Color and State
Description
Off
A physical link has not been established
Solid Amber
Indicates an active physical link
Blinking Amber
a
4 Hz blinking Amber indicates a problem with the physical link
Solid Green
Indicates a valid logical (data activity) link with no active traffic
Blinking Green
Indicates a valid logical link with active traffic
a
1 Hz Blinking Amber occurs due to running a beacon command for locating the adapter card.

Heat Sink Interface
The heatsink is attached to the ConnectX-6 IC to dissipate the heat from the ConnectX-6
IC. It is attached either by using four spring-loaded push pins that insert into four
mounting holes, or by screws.
ConnectX-6 IC has a thermal shutdown safety mechanism which automatically shuts
down the ConnectX-6 card in cases of high-temperature event, improper thermal
coupling or heatsink removal.
