Hey all, Ok, so I got the 1000' of Cat5e, a bunch of RJ45 Cat5e-certified jacks, faceplates and modules, etc. And I wired the crap out of the place. Being a complete dork, I didn't test the first wire I put in. I just put in about 12, punched everything down (using the 568B scheme), and THen plugged a machine in one end and patched over to the switch on the other end. Link light comes on, 100M light comes on, DHCP server sees machine send request, machine doesn't see DHCP server send reply. I tested all the cables outside the walls and they're fine. I tried several different machines and NICs, and it looks like they can all transmit and not receive. Naturally I have no Cat5 testing equipment, but I opened up a few plugsto make sure I _did_ in fact punch everything down correctly, and it looks like I did. Anyone have any clues/suggestions? -Yaron --
