Have a new ACS that customer says is rebooting during the day for no reason. Sets go dark till system restores. Have change UPS & Processor. Reseated all cards in 5 slot CXR. It Happens about 1 or 2 times a week. Checked with Avaya and they have no none problems with this new release. Antone else having a similar problem?
This is an ACS Rel 7.0 91O version.

Does this happen at the same times or is it random?

Well, if you changed the ACS processor and you know it's not a power problem I would start looking at the other modules. Swap them out one by one with a known good mod until the problem goes away.

But before I did that I would make sure that the temperature at the KSU is maintained at less than 85 deg F. I have see this problem caused by heat. Last time was in the middle of winter and a ceiling louver was blasting the KSU.

hslingland,
By any chance is this the same one with a voicegate Wizard with outcalling mail system behind it that gave you the same trouble 3 years ago?

We have several many R.7 "O's" out in the field up and running and we have never saw this problem.

Sounds like there needs to be some on-site troubleshooting. Switching out cards, VM's and maybe even put a data logger on the AC voltage feeding the processor. Not all battery back-ups are created equal.
I have saw some of the cheaper UPS's give enough of a voltage drop when switching to cause a flicker.

Is the UPS pluged into an outlet that is atatched to a light switch. Trace it back to electrical panel and make shure.

yes, it has happened to 2 sites so far.. Installing another at a new site soon. I will keep my fingers crossed, as it is 2 for 2 in problems.

Had this problem once at a site, come to find out the tech that installed the system left a old bis 10 hooked up when he installed the new system. IT was in a old fuel bay and never saw it..

I had one out of the box do it before install , I was set up and programing and it was doing it every 5-10 min o rs . I just assumed a bad processor and returned it

I had the problem System would just shut down. A power cycle would fix it for a while. We ended up replacing the Processor. It was an O
