Two days ago we had some problems with our network on work and went to check it out. And we came to a conclusion that something is making our net block. We have this one network cabinet which is in the old building across the street conected with optic cable with the main building and then the network spread across the offices. And something there was blocking the optical connection.
I forgot to take a picture before I started fixing this, but there was a bunch of cables connected in two switches, also optical cable, and the telephone network, and a Mikrotik connection, and it was all just a mess. So there was no other way but to disconnect everythin and to reconnect it again.
This is half way through the procces.
Sa basicaly at this point I am trying to figure out which of these cables are working and where the working cables lead. After that only 16 of the cables needed to be connected to the network, and was left with at least 15 of them that was not necessary. So I removed those and connected the 16 that worked.
A little cleaning up, a little rescrewing, getting rid of the unnecessary cables, a little duck tape and the most important thing was writing down where the cables lead.
The network works just fine now, everything is clean and dandy. It took me one working day but it is better to do it now, then to do it when it all colapses.
