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
xg
N
, 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
10
007–4669–003
