Performing Troubleshooting and Diagnostic Tests
7-8
1. Make sure the board is seated correctly in the slot.
Remember that the EISA slot is deeper and requires
firmer pressure to seat the adapter correctly. Check
the adapter installation by reviewing the installation
instructions in Chapter 1.
NOTE: The maximum bus speed supported by the
EtherLink III adapters is 10 MHz.
2. Inspect all cables and connections.
If you are using thin Ethernet cable, make sure that
you have a T connector attached to the adapter and
all other adapters on the network. Make sure that the
thin Ethernet segment is terminated at both ends with
a 50-ohm terminator.
3. Make sure that you booted your computer under
DOS version 3.1 or later and that no device
drivers or memory managers are loaded.
4. If you are running the Group 2 test (only on the
3C509 coax, 3C579 coax, or 3C509-COMBO coax
adapter), make sure that the loopback plug is
securely attached to the adapter’s BNC connector
or that the adapter is attached to a properly
cabled and inactive network.
If this test fails, try another loopback plug.
5. If you are running the Group 3 test, make sure
that the adapter is connected to a properly cabled
and inactive network and that an echo server is
set up on the network.
