Network Cable – RJ45 Troubleshooting

This document will describe various methods for detecting a defective network cable.  We are constantly updating documents.  The information contained here may change without notice.

1. Connect 4-pair cable tester to the ends of the cable.  Follow the directions of the tester to determine if the cable is good or bad.  If you test the cable and do not get good continuity than examine the connectors or patch panel port on each end. Replace or re-terminate them as necessary. If it tests good then try the continuity again but this time with and through the patch cords on each end.
2. If an extra cable is available, connect it in place of the current cable. This will assist in isolating the issue to the cable only.
