I was in the process of rewiring the "Computer Lab" (Library) at my son's Elementary School from 10bT to Cat5.
In order to map the network & figure out how much Cat5 I'll need, I grab a pencil, paper, clipboard, & start tracing the network.
Right off the back of the Server was a section of 10bT on a splitter, and couldn't figure out why:
A) The network worked, since I didn't know if it was properly terminated
(Ok, so the fact that it WORKS, means it IS properly terminated, but *WHERE*?)
B) What it went to
So I mark the end closest to the Server with a label, and start crawling under everything following the cable...
Around doorways, down a hall, up a wall, into the false ceiling.
Crud....
Get a ladder, climb up into the crawl space...
The cable goes across a run of braces, up the length of the Library building, & back down through the ceiling.
I run the pencil with the paper on it down the hole to "flag" the location, and go back to where I left the ladder I used to get up here in the first place.
Find the "flag", which comes down in the Receptionist's area just outside the Computer Lab, down the wall along a black board, & through a hole in the Library wall near the floor.
Go to the other side of the wall, inside the Library (Computer Lab, remember?), and follow the cable along the wall, around a corner, and to the other end of the 10bT splitter I'd started at.
*FACE PALM*
The "loop" INSIDE the Lab was merely a smaller loop off the BIG one, and the BIG one tried to go around the entire main building.
I bet the guy who laid it couldn't figure out why he wasn't getting a signal on the big loop - something about being about FIVE TIMES the maximum un-amplified length for 10bT perhaps?
