Chapter 11: Troubleshooting

Before you open the cabinet of your server to add or remove the 
adapter, see “Reviewing Safety Precautions” on page 29.

The following checklist provides recommended actions to resolve 
problems installing or running the AT-2973SX, AT-2973T, or AT-2973T/4 
adapters in your system:



Inspect all cables and connections. Verify that the cable connections 
at the network adapter and the switch are attached properly. Verify 
that the cable length and rating comply with the requirements listed in 
“Connecting the Network Cables” on page 38. 



Check the adapter installation by reviewing “Installing a Network 
Adapter Card” on page 34. Verify that the adapter is properly seated in 
the slot. Check for specific hardware problems, such as obvious 
damage to board components or the PCI edge connector. 



Check the configuration settings and change them if they are in conflict 
with another device. 



Verify that your server is using the latest BIOS. 



Try inserting the adapter in another slot. If the new position works, the 
original slot in your system may be defective. 



Replace the failed adapter with one that is known to work properly. If 
the second adapter works in the slot where the first one failed, the 
original adapter is probably defective. 



Install the adapter in another functioning system and run the tests 
again. If the adapter passed the tests in the new system, the original 
system may be defective. 



Remove all other adapters from the system and run the tests again. If 
the adapter passes the tests, the other adapters may be causing 
contention. 

This section describes how to check that the current drivers are loaded 
properly for the Windows and Linux platforms.

See “Viewing Vital Signs” in the Broadcom Advanced Control Suite 3 User 
Guide to view vital information about the adapter, link status, and network 
connectivity.
