Sun FastEthernet PCI Adapter Product Note • August 1997
Using the
test net
Command on an
Adapter With an External Transceiver
If your adapter is connected to an external transceiver, you will see incorrect error
messages when using the OpenBoot PROM (OBP)
test net
command. Although
the
test net
command will pass the first time it is used, it will fail on subsequent
tests, even though the Ethernet interface is functional and can be used.
You can avoid seeing these false test failures by using the OBP
reset-all
command between testing the adapter with
test net
command. Refer to bug id.
4062368 for more information.
Note –
Refer to the OpenBoot 3.x Command Reference Manual (part number:
802-5837-xx) for more information about the
test net
and
reset-all
commands.

Known Problems
The following sections list the known problems and workarounds if they exist.
Fiber Optic Transceivers
The Sun FastEthernet PCI adapter’s MII interface does not support external Fiber
Optic (FX) transceivers. However, the adapter’s MII interface does support TX, T4,
and AUI external transceivers that comply with the IEEE 802.3u standard.
Refer to bug id. 4062714 for more information.
FastEthernet Switches (100BASET)
There are two FastEthernet (100BASET) switches which currently do not operate
with the Sun FastEthernet PCI adapter:
■
Bay Networks Model 28115
■
Fore Systems (all models)
