Laser Link bringing down network
Can anyone shed any light on this problem, possibly someone has had something similar happen? Last year I had a laser link installed to allow a seperate building access to the network. This was working fine until a couple of weeks ago when all the workstations on the network hung, and rebooting the server had no effect. Thinking it was a switch failure due to the hot weather (server and switches are kept in a small cupboard, gets v. hot in summer months, but at least I was finally able to persuade them to get me an air conditioner unit!) i was troubleshooting along those lines when I realised that all would work well until I plugged in the patch cable running (via a POE injector) to the laser unit, carrying out a continuous ping to the router from the server whilst plugging unit in and out confirmed it was dropping the connection when plugged in. As far as I am aware, the laser unit doesn't use an IP address as its just a medium to transfer data (as is a normal cat5 cable), I've even terminated the link into a different patch panel with no difference. Just can't understand why this would affect the link to the router, they're not even on the same segment of the network, anyone think of something else I can try?
