I have a 2250 on an Opt11 25.40. It was working perfect two days ago and now it won't light up. I looked at the history to see if something happened on the switch that I wasn't aware of but everything was fine, no power issues no restarts no software issues. The 2250 is about 20' from the switch so I connected only the two tn's. This is the way that is has been working for years. I thought it might be a bad card so I changed it, no luck. I outed the 2250 and built it on a new card starting at 2-0 and 2-1. I also built the pwr tns just because. If I hook the power tn's to the 2250 it lights up. Date says 1 Jan 89. At no time did I get the correct time and date because for some reason the console doesn't see the tn's. I took it to the switch and made a cat5 cable to a female db-25 connector. First tn goes to 2(ring) and 14(Tip) second tn goes to 3(ring) and 15(Tip) 17-5 +aux 18-6 -aux. With this the console lights up like I described before but none of the keys work and still the date of 1 Jan 89. I have another m2250 and tried it and the same thing. I took both M2250 and the cat5 cable I made to my other site that is setup the same and both consoles work perfect. When I hookup a 2616 to the first tn I get the correct date and time. I know I wont get any thing from the secondary tn on a 2616 so I didn't try. I have done a cold start on the switch and that didn't work either. I have tried everything that I could think of to get this console to work but it won't. Any help would be very appreciated.
