Ethernet Connection Problems

  Ethernet Connection Problems


NOTE:

1.  If you use the integrated Ethernet controller, you must use Category 5 cabling.  See 'Ethernet Cable Specifications' for additional information about Ethernet cable  requirements.
2.  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:

1.  Verify that the cable is installed correctly.
2.  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:

   1.  Make sure that the hub and network are operating, and the correct device drivers are loaded.
   2.  There might be a defective Ethernet connector or cable, or a problem with the hub.

3.  Make sure that you are using the correct device drivers that come with the server.
4.  Check for operating system-specific causes for the problem.
5.  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'
