The 802.3af/802.at PoE (Power over Ethernet) Tester, connected to an RJ45 outlet, allows you to test a live Ethernet cable and determine if both power and data are present. This unit is an easy-to-use Power over Ethernet adapter for professionals, business and home users to determine the existence of PoE.
The Doss NF-469 twin-end multifunction port flash cable checker checks network and telephone cables for continuity. It also helps with tracking network cables back to the switch by flashing the cable port.
Sometimes, it is hard to find patch leads or port numberswhen there is a bunch of them tied and connected to the patch panel.
One easy solution might be to plug in one end of the patchlead into the NF469 tester, when it is set to port flash mode, you will see the led flashing on the patch panel, either on port or front panel.
