4.1.3 PCI Express Interface

The ConnectX-2 adapter cards support PCI Express 2.0 (1.1 compatible) through an x8 edge con-

nector.

4.1.4 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 illuminates 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.

Figure 8: Physical and Logical Link Indications

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

4.1.5 I

C Compatible Interface

A three-pin header on the adapter card is provided as the I

C compatible interface. See

Figure 13,“Schematic of the ConnectX-2 MHZH Adapter Card” for the location on the board.
