8.7Testing the Ethernet
After the correct Ethernet port has been located, it can also be fully tested using the
>>>show ewa0_mode
ewa0_mode
Be certain that the media type is correct for the network the port is plugged into. Valid types for this module are:
Twisted–Pair, Fast, or FastFD.
To test the circuitry on the Ethernet port do an internal loopback test on the Host Adapter by using the NETTEST diagnostic at the SRM console.
>>>nettest ewa0 -mode internal -pass 0
>>>show_status
ID | Program | Device | Pass | Hard/Soft Bytes Written | Bytes Read | ||
00000001 | idle system | 0 | 0 | 0 | 0 | 0 | |
00004cf1 | nettest | ewa0.0.0.300 | 94 | 0 | 0 | 24342 | 24064 |
This test will continue to test the port until interrupted:
>>>kill_diag
You should see no Hard or Soft errors during this test.
Use the LED’s on the Host Adapter handle to determine the speed of the port, and the LINK status.
∙If the module is correctly wired to the network hub, the Ethernet Link LED is lighted.
∙If the EWn0_MODE for the port is at FAST or FASTFD, the 100 MB Mode LED is lighted.
∙If traffic is detected on the bus, the Ethernet Activity LED blinks.
If the speed or media type of the port does not match that of the hub, use the set ewa0_ mode fast command as follows:
>>>set ewa0_mode fast
Where the mode is Fast, FastFD or
