Same here. When I was installing for Telco, had a buddy you could write on those blocks so neat it looked like a professional print job. Mine you can usually make out, if you squint real hard. :rolleyes:

Too many compliments. Try: https://www.dslretorts.com/Paladin/images/UglyLAN.jpg

You can see part of the house cable on the left side of the picture. Beans... 50-pin amp connector hanging....

I installed my first LAN in there somewhen around '94. They said EOTP was designed to go over existing voice wire, so I did. The picture is actually of later upgrades, but even so you can see where I split a four-pair into two ethernet connections.

Thanks for the photo's Mike

Now you come out with the "down and dirty" photo's. LoL
But I'll bet you that just about every one of us have been a little guilty of something just like it.

That was not on the same system was it Mike?

Wow, that looks awfully familiar. Like most closets around here. And they wonder why the phone system "doesn't work" or "the computers are down". Hmm..

There's your sign.

wow. just wow. what a complete 360 from the first pic to the second
nice work!!

Once on a bet we installed a 16c rack apparatus with 2 full 584c panels upside down. This was in an Air Force Command building in a stairwell where you had to take the cover off to realize everything was upside down. You could see techs laughing at it as the cables came out the top and over to 66 blocks instead of out the bottom.

That's no problem. Just plug the interrrupter in backwards and the line cards upside-down and it works fine. Oh, and don't forget to connect your ground to the hot side of the power supply to keep things consistent.

I have a better idea. Mount it on the inside of the closet door so that when the cleaning people slam it after taking their brooms, mops and buckets out, all of the line cards will fall out. You pull off the cover to test for troubles and end up with a dozen line cards on the floor. Of course a snake inside of the cover would probably be less of a shock.

Now I know what that stupid locking bar with ten screws was for... It was to protect the system from cleaning people when racks are mounted on doors!

Boy Ed that reminds me of one. I went on a trouble call on an 756 PBX (hotel motel) when I got there, there were relay caps everywhere. I asked the manager what happened and he said he just pulled out the rack door and slammed it back shut to try to clear the trouble, as he had seen one of the "techs" do many times. Don't know how many of you have ever seen a large X-bar switch with literally hundreds of flipped wire springs on relays. Oh what fun, I was there for hours. I put the pins in all the doors, very tight, when I left.

Then you just turn it upside down and everything is fine! Better yet, mount it sideways and maybe gravity will keep it in check each time the front door slams.

Fixing wire spring relays is easy. Just use Picabond connectors to correct them. Seriously, I know what you mean. Straightening those things is like threading individual hairs through a comb.
