4-10 CHAPTER 4: PERFORMING TROUBLESHOOTING AND DIAGNOSTIC TESTS

Check the length and rating of the UTP cable connection. Make sure the cable segment is compliant with 10BASE-T or 100BASE-T4 specifications. Maximum length for all types of cabling for this adapter is 100 meters (330 feet).

Make sure that you have installed the correct driver for the network operating system you are running (refer to Chapter 3,“Loading the Network Drivers”).

If any problem persists, refer to Appendix D, “Technical

Support.”

LEDs

Each 10/100BASE-T4 PCI adapter has three LEDs, as shown in Figure 1-1 and described in Table 4-2.

The adapter must be physically connected to the network and network drivers must be loaded for the LEDs to work.
