6.Type the following to run the selftest using the test command on one of the adapters four Ethernet channels:

ok test <device path>

The following tests are run when the test command is executed:

hme register

MAC internal loopback

External loopback

100 Mbps PHY loopback

10 Mbps PHY loopback

If the test passes, you will see these messages:

Hme register test --- succeeded. Internal loopback test -- succeeded

Transceiver check -- Using onboard transceiver -- Link up passed

If the channel is not connected to a network, you will see the following error messages:

Hme register test --- succeeded. Internal loopback test -- succeeded

Transceiver check -- Using onboard transceiver -- Link down Autonegotiation timeout

Check Cable or contact system administrator Failed

selftest failed. return code = -1

Note To test other channels of the adapter, you will need to execute the test command separately on each channel.

7.After testing the adapter, type the following to return the OpenBoot PROM to standard operating mode:

ok setenv diag-switch? false
