Ethernet Connection Problems
Ethernet Connection Problems
NOTE:
- If you use the integrated Ethernet controller, you must use Category 5 cabling.
See 'Ethernet Cable Specifications' for additional information about Ethernet cable
requirements.
- If you directly connect two workstations (without a hub), or if you are not using a hub
with X ports, use a crossover cable (a UTP cable that is wired as a straight-through cable).
To determine whether a hub has an X port, check the port label. If the label contains an X, the hub has an X port.
If the Ethernet Adapter cannot connect to the network, do the following:
- Verify that the cable is installed correctly.
- Check the Ethernet activity light on the front of the server.
NOTE: This light is off when you run the diagnostic programs in the
Configuration/Setup Utility program.
If the Ethernet activity light is off:
- Make sure that the hub and network are operating, and the correct device drivers are loaded.
- There might be a defective Ethernet connector or cable, or a problem with the hub.
- Make sure that you are using the correct device drivers that come with the server.
- Check for operating system-specific causes for the problem.
- Test the Ethernet controller or adapter.
How you test the Ethernet controller or adapter depends on which operating system is being used
See 'Configuring the Ethernet Controller'
