For a fiber optic port, verify that the port on the network adapter card
and the port on the remote device are operating with the same duplex
mode. All of the adapters described in this guide have a default setting
of full-duplex for the fiber optic port. To configure the duplex mode of a
fiber optic port, you can use the AT-Diag utility, explained in Chapter
10 on page 175 or, if the system is running Microsoft Windows 2000,
2003, or XP, you can perform the procedure “Configuring the Network
Adapter Card Settings” on page 91.
ˆ
Run the AT-Diag utility and perform the Diagnostics Test to test the
network adapter card’s components.
ˆ
Run the AT-Diag utility and perform the Communications Test to test
the quality of the communications path between the card and the
remote device.
ˆ
If system is running Microsoft Windows 2000, 2003, or XP, perform the
procedure “Configuring Additional Network Adapter Card Settings” on
page 96. Check the VLAN ID value. If the network adapter card is
handling only untagged packets or if you installed the AT-MUX utility,
the VLAN ID value should be 0 (zero). If the adapter will be handling
tagged packets from just one VLAN, this parameter should be set to
the corresponding VID value. For further information, refer to “Virtual
LANs and the AT-MUX Protocol” on page 37.
ˆ
Power off the system and try installing the network adapter card in a
different PCI slot in the system.
The BootPROM chip and MBA are not functioning:
ˆ
For a dual port network adapter card, check to be sure that only one
port is connected to the network.
ˆ
Perform the Diagnostics Test selection in the AT-Diag utility. If the
BootROM Checksum Test fails, the network adapter card has a
problem. Replace the card.
ˆ
Use the AT-Diag utility to verify that the BootPROM chip and MBA are
activated on the card. The BootPROM chip is controlled with the
Settings option in the main menu of the utility.
ˆ
For a dual port network adapter card, use the AT-Diag utility to verify
that the port connected to the network has been designated as the
default port for MBA. The default port is controlled through the Settings
option in the main menu of the AT-Diag utility.
The link light is on but no cable is connected to the network adapter card:
ˆ
This could indicate a failure of the network adapter card. Perform the
Diagnostics Test selection in the AT-Diag utility to test the card’s
components.
