Network Interface Card (Installed) Problems

See the appropriate Network Interface Card documentation.
Symptom:
•
The NIC adapter cannot connect to the network.
Action:
1. Ensure the cabling is installed properly.
2. If you're directly connecting two servers (with no hub or other device), use a "crossover" cable.
Most hub and switch connections require a straight-through cable; but consult the documentation.
3. Verify there are no resource conflicts between the NIC and any other accessories in the server.
4. Check the (BIOS) Setup Utility for resource conflicts.
To start the (BIOS) Setup Utility, boot or reboot the system and press F10 when prompted.
5. Check the LEDs on the adapter at the back of the server to see if any show activity.
No lit LEDs probably indicate a bad network cable, hub connection, or other network error.
6. Ensure you're using the latest and most correct drivers.
7. Verify the drivers are intended for this NIC adapter.
8. Ensure the port on the switch or hub (or other device) has the same duplex setting as the adapter.
9. If you configured the adapter for full duplex, make sure the switch port is also configured for full duplex.
Setting the wrong duplex mode can degrade performance, cause data loss, or result in lost connections.
10. Test the adapter as directed in the installation tasks for each operating system.
11. Also check the "README" files on the support disk provided by the NIC adapter vendor.

Installation Problems

To troubleshoot an installation problem, you need to determine if the problem is hardware or software related.
1. Verify all cables and boards are securely plugged into the appropriate connectors or slots.
2. Ensure the server is configured properly.
Most installation problems are the result of incorrect BIOS and SCSI configurations of the server.
a. Verify that the system BIOS is the latest. See
b. Verify the SCSI BIOS configuration. See
c. If the network is not functioning, consult your network operating system manual and its requirements.
To determine if the problem is a hardware error, follow these steps:
1. If necessary, log users off the network and back up the server.
