ACS R7 system resets

[thephonelady]

My customer has an ACS R7.0 91K with a T1 and says the system resets occasionally. If she is on a call when this happens the screen goes blank and comes back on in a few seconds. I looked at the maint. logs and there are no errors on the T1 however there are a lot of reset events. 36 power up coldstarts and 50 software initiated cold starts. She seems to think this started after the T1 vendor made some changes. The problem is sporadic, maybe once a week, sometimes a few times a day or sometimes once a month. I powered down and reseated all of the modules. Any ideas?? Thanks in advance.

1 of the power units in a module may be going bad,when its going down you may be able to notice the power light flashing on the module in question ,the rest will be solid green

I believe the power up coldstart event could be power related from a power failure, or similar interruption, or possibly a power supply problem. Along with the screen going blank on the sets, that would indicate something happening with the power source or supply. Is the unit on a UPS?

Check your UPS, bypass it for a day or two.
