I have a UNI card on a new v4.65 that seems to keep going to sleep. It has a digital card, analog card and CO card on it. All the lights go orange and the phones go blank.

The alarm log is empty and if I do a card reset in software it doesn't do anything. It says it's running.

A reboot brings it back online for a week or so but then it goes to sleep again.

Whaddya think, before I call tech support? Bad UNI card?
