Its important for analysts to have basic tool to test their equipment and cables.
The other day I needed to replace a POE injector on a roof and wanted to make sure that the one I found in my box of goodies actually works.
I’ve been in many situations where the equipment or cables I find in a box is there because it doesn’t work.
So I used me pockethernet (www.pockethernet.com) to test the link, poe and network connectivity and thought I would share.
Having layer 1 test tools is not optional for me since I cant tell you how many issues I resolved that were at layer one.
