Chapter 3 Troubleshooting 3.1 Improper Network Cabling and Topology Improper network cabling or topology setup is a common cause of poor network performance or even network failure. Figure 13 Troubleshooting Improper Network Cabling and Topology PROBLEM CORRECTIVE ACTION Faulty cables Using faulty network cables may affect data rates and have an impact on your network performance. Replace with new standard network cables. Non-standard Non-standard cables may increase the number of network collisions and cause other network cables network problems that affect your network performance. Refer to Section 2.2.2 on page 14 for more information on network cable types. Cabling Length If you use longer cables than are needed, transmission quality may be affected. Too many hubs between the computers in the network A loop in the data path The network cables should not be longer than the limit of 100 meters. Too many hubs (or repeaters) between the connected computers in the network may increase the number of network collision or other network problems. Remove unnecessary hubs from the network. A data path loop forms when there is more than one path or route between two networked computers. This results in broadcast storms that will severely affect your network performance. Make sure there are no loops in your network topology. ES1100 Series User's Guide 21
