KZPCM PCI–to–Dual Channel Ultra SCSI and 10/100MB Ethernet Host Adapter
8–6 EK–KZPCM–UG. B01
8.7 Testing 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

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.
