KZPCM PCI–to–Dual Channel Ultra SCSI and 10/100MB Ethernet Host Adapter

8.7Testing the Ethernet

After the correct Ethernet port has been located, it can also be fully tested using the built-in diagnostic NETTEST. This test is capable of doing both an internal and external loopback test. First you must determine that the MODE is correctly set for the media (wire) type that is connected to the module.

>>>show ewa0_mode

ewa0_mode Twisted-Pair

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 Twisted–Pair , consistent with your network. The speed and link light will indicate correct operation.
