During normal operation, the link LED is on; the data LED blinks whenever the adapter is receiving traffic.

Note: At the time of release, a bug in the driver prevents the link light from behaving correctly. The link light may be on or off due to this bug. This problem will be corrected in a future release.

Verifying Adapter Recognition

This section discusses verifying the adapter recognition for IRIX and Linux.

IRIX Adapter Recognition Verification

Under IRIX, the network interface name for the SGI 10-Gbit Ethernet network adapter is xgN, where N is the number of the adapter: 1 for the first adapter, 2 for the second adapter (if installed), and so on. Use the commands in the examples below to display the network interface names.

Note: IRIX uses /etc/ioconfig.conf to keep adapters and unit numbers consistent between reboots and new hardware installs. As a result, if a adapter is removed, it’s interface name will be reserved until it is removed from /etc/ioconfig.conf. As a result, if you move adapters around the system or remove adapters, you may see some interface numbers get skipped.

To verify that the operating system has located the adapter, enter the following:

irix% /bin/hinv
