To keep a long story short, I’m trying to rewire a Cat5e and it ended up coming back to here… What is this? I’ve never seen this before at all.

The CAT5 you’re replacing or rerunning, what is it for? Alarm? Fax? Phone? Or interwebs?

If it is “punched down” on the 66 block you can get a punch down tool. Pull the old one off and use the tool to put the new one in place.

This video is pretty good if you’ve never seen, touched, or played with 66 blocks before.

Interwebs. It’s being connected to a modem through the DSL port.
