8 Troubleshooting the NIC863 Check the computer BIOS. Boot the computer and enter the BIOS. For instructions on entering the BIOS, refer to the computer documentation orconsult the computer vendor. Locate the Wake-Up on LAN event setting. Verify that the setting is enabled.4 Check the Remote Wake-Up cable connection.If the computer complies with PCI 2.2, the Remote Wake-Up cable is not required.Remote Wake-Up is automatically enabled through the PCI bus. Turn off the power to the computer and remove the computer cover. Make sure that the Remote Wake-Up cable is plugged in to the RWU connector onthe NIC and in to the appropriate connector on the computer motherboard.Unplug and reinsert the cable if necessary. Replace the Remote Wake-Up cable with a known functioning Remote Wake-Upcable and perform the Remote Wake-Up Test again.5 If the previous steps have failed, install a known functioning Remote Wake-Up NIC inthe computer.If Remote Wake-Up works with the new NIC installed, consult your computer vendorfor a replacement NIC.If Remote Wake-Up does not work with the new NIC installed, there may be aproblem with the computer motherboard. Consult your computer manufacturer.Troubleshooting a Network ConnectionWhen working with 10BASE-T or 100BASE-TX cabling, concentrators, and NICs fromdifferent vendors, it is possible to connect everything but still have no networkcommunication.To narrow the range of possible causes of common network connection problems:1 Determine whether your equipment complies with the 10BASE-T or 100BASE-TX standard.This is particularly important for data concentrators (hubs or repeaters).2 Connect a straight-through cable from the PC to the hub.The hub performs an internal crossover so that the signal can go from TD+ to RD+and TD– to RD–. When you look at an RJ-45 connector from the front (that is, theopposite side from where the wires enter the connector), pin 1 is identified on theright side when the metal contacts are facing up.3 Make sure that the TD+ and TD– wires are twisted together, and that the RD+ andRD– are twisted together.Using wires from opposing pairs can cause signals to be lost.NOTE: For additional network troubleshooting information, see “Running NICDiagnostics” on page 91.
