Network Connectivity Issue: Unlabelled Connections

What is the main issue identified by the technician?

The main issue identified by the technician is a network connectivity problem at a workstation. What could be the potential causes for this issue?

Upon investigation, the technician found that the link light on the workstation is not lit, and there is no connectivity even after replacing the patch cable with a known good one. The wall jack and the cables in the switch room are not labeled, making it difficult to trace the connection lines. This lack of labeling could be a significant factor in troubleshooting the issue.

The primary suspicion is that the workstation's network interface card (NIC) might be defective, leading to the connectivity problem. However, since the issue persists after replacing the patch cable, the problem could possibly be at the wall jack or further down the line, possibly in the switch room.

Proper labeling of connections is crucial in network troubleshooting to easily identify where each cable is running and to quickly spot any defective components. In this case, the technician should start relabeling the connections from the workstation to the wall jack and then through the switch room to properly diagnose and fix the issue.

Potential Causes of the Network Connectivity Issue:

1. Defective network interface card (NIC) on the workstation

2. Faulty wall jack or connections in the switch room

3. Lack of labeling on cables and ports making it difficult to trace connections
