1721 that has continuosly blinking OK LED.

We have a 1721 with a WIC-1t serial module. We installed it about a month ago and have had no problems. The last couple of days it appears to hang. The OK led flashs continuosly with no apparent pattern and the WIC 0 light is off. I am very new at this. Does anyone have any ideas?

Re: 1721 that has continuosly blinking OK LED.

Is the wic listed on "show version" ?? remove the wic and reinsert it and see if its being detected and working properly.

Is the wic connected to a csu/dsu ??? if yes, can u check if the csu/dsu is working ok ?? There could be a possibility of a broken csu + wic, due to lightning surges.

Sorry yes it is connected to a CSU/DSU. We are having the line checked out and will try removing the WIC. Thanks for the advise.
