It’s been documented that “…nearly 70 percent of all network-related problems can be traced to either poor cabling installation or problems with the cabling components.” 1 The likelihood for live cabling and components to sustain damage is high as cable technicians gradually enforce the National Electric Code’s declaration to have abandoned cables removed. And even in daily operational activities within telecom closets and computer rooms, it’s possible to damage cables and terminations as equipment and connections are moved.
When damage is sustained, an organization cannot solely rely on Network Management Systems (NMS) to manage the network and troubleshoot problems. Here’s a possible scenario:
- An NMS signals an alert or a user calls the Service Desk complaining of connectivity issues.
- The service desk checks the local switch to see if it is down or if a port has been disabled – everything is working.
- Next they check the user’s station device to try to ping the switch – no response.
