Hi folks,

I have a 7400 with expansion cabinet running 4.98.
Just recently, the alarm history is showing a bunch of Red Alarm and recoveries. Anywhere between 3 hours and 3 minutes between instances. Maybe once a day there is also a L2 Disconnect.

Any advice? The manual says the red alarm is a switching stack failure. Could that be caused by the carrier?

Thanks in advance.
