- Use the proper cabling for your network topology as specified by IEEE. Make sure cable segments do not exceed the recommended lengths.
- Make sure cable segments are properly terminated for the type of cabling being used.
- Make sure terminators and in-line cable connectors are working properly.
If you are not sure whether a terminator or connector is working properly, replace it. If the new components work properly, discard the old ones.
- Make sure there are no breaks in the cable or shield. Use a time delay reflectometer (TDR), a LANalyzer, or a volt ohm meter (VOM) to test cabling for breaks in the cable conductor or shield.
- Make sure cabling is routed away from devices that produce high electric or magnetic fields, such as fluorescent lights, microwaves, radar, X-rays, copy machines, etc.
