The desired port configuration will then be set for the selected device. Note: This utility also has a
non interactive mode:
"/sbin/connectx_port_config [[-d|--device <PCI device ID>] -c|--conf <port1,port2>]".
2.1.3 PCI Express Interface
The ConnectX
®
-2 adapter cards support PCI Express 2.0 (1.1 compatible) through an x8 edge con-
nector. The device can be either a master initiating the PCI Express bus operations or a slave
responding to PCI bus operations.
2.1.4 LED Assignment
The board has I/O LEDs located on the I/O panel. The green LED, when lit, indicates that the
driver is running and a valid physical connection between nodes exists. If the green LED is blink-
ing, it indicates a problem with the physical link. The yellow LED when lit, indicates a valid data
activity link, this is the logical link. The yellow LED lights up when the network is discovered
over the physical link. A valid data activity link without data transfer is designated by a constant
yellow LED indication. A valid data activity link with data transfer is designated by a blinking yel-
low LED indication. If the LEDs are not active, either the physical link or the logical link (or both)
connections have not been established.

The short bracket has the same port and LED footprint as the tall bracket.

LED Name
Physical Link - Green
Constant on indicates a good physical link
Blinking indicates a problem with the Physical link
Data Activity - Yellow
Blinking indicates Data Transfer
Constant on indicates no Data Transfer
