We had gear in the MFS Colo in Whippany, NJ. We had a couple routers (2501's and a 4700M), a couple PM3's, and some other crap. Near us were TNT's and Total Controls from ANS (remember them??). 

Yeah, it got warm in there, especially when the single 10 ton AC unit failed (about every other day).

But, it was way more fun back then.
