3: Operating the Adapter

Table 3-1

LEDs on the SGI 10-Gbit Ethernet Network Adapter

LED State Purpose

ACT Blinking

Off

Data detected

No data detected

LINK On

Off

Good link

No link: faulty cable, faulty connector, or

communication mismatch

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

IRIX 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

A line similar to the following should appear, where N is the number of the adapter:

Gigabit Ethernet: xgN, module 001c10, PCI bus 0 slot 1

8 007–4669–001

1 2 ... 17 18 19 20 21 22 23 24 25 26 27 28 29 30
