Shoutout to the $12 cable tester that shamed me after years of swapping ports
I spent years fixing network drops by swapping ports and blaming the switch, then last month a $12 cable tester showed me a bad crimp on a run I did back in 2021. Half the tickets I closed at that office in Fresno were probably that one cable, and I keep thinking about how many callbacks I ate because I trusted the link light. So here is the argument: is a tester worth the money when a link light and a ping feel like enough, or are we all just guessing until something breaks? Our crew is split, two of us swear by testing every run before it gets closed up, the other two say it slows the day down for a rare problem. Which side is closer to how you work, and what finally made you start testing?
