Good morning, i'm using this port adapter on 7206VXR device with

12.4(13a) IOS release. Is there anyone that is having some problem with this card when the router reload? I'm explaining better: i have two router connected with some E1 links through SDH network. When I make the reload of one of the two router the E1 links seem going in a status like "freeze" and to reestablish the correct working i have to disconnect the link on the telco rack.

Many thanks in advance

I have a 7206VXR (NPE400) with 4 PA-MC-8TE1+ installed. Some years ago we had problems with some of the E1 lines and we had to disconnect the cable to fix them.

We asked the SDH guys to check the lines and they found out that our rack was not grounded properly and that caused the lines not to work. As soon as we fixed it we never had any problems.

I never really understood why disconnecting a cable made the grounding problem dissapear for a while, but ...
