BCM 450 Release 6 Multiple phones initialize, system appears to be restarting, no errors

[talkunity1]

Customer reports that their BCM450 appears to have "restarted" itself, causing many digital sets to re-initialize, calls dropped, etc.

Prior posts indicated there was an issue with event logging that could cause random or even daily reboots, and there are also posts about power supply issues. This is the first time the system has "restarted" itself, and the system has been continuously powered for over 6 months, and is on a new line-interactive UPS. Event logging is not being used.

Any thoughts? I am leaning towards power supply issues. Is there any log file growth issue I should be looking for? Anyone have long-term uptime experience with the BMC450 for longer than 6 months continuously? We have Nortel MICS systems with continuous uptimes of more than 8 years. The BCM450 seems much less reliable...

Thoughts?

Do you have redundant or single power supplies in your 450? I've got quite a few and haven't experienced this issue. Most of mine were deployed with redundant power supplies.

This particular BCM450 has a single supply.

Those power supplies, it's the same model as in the 400's, have caused me no end of trouble. I believe the Operational logs are not encrypted on the 450. You can download those and look at the psmtest.log. See if anything there jumps out at you.

Check some of my previous threads as I've come across this type of problem on a 450 release 1 system. We found that the small circuit board that resides in the middle of the chassis that connects between the power unit, modules and Motherboard had gone H/R when it heated up causing one of the soldered wires to fail.

We had no warnings, but the BCM 450 could fail at anytime between 1 and 4 hours, depending on how long the BCM had been left turned off!. We just replaced the entire chassis, but retained the original motherboard / hard disk as it was all in one unit and therefore we didn't need to get any keycodes changed.

We had no warnings when it failed. I proved this by connecting up the serial port using 115200 baud and I had a capture file running. No alarms an no warning. It just rebooted and rebooted etc.

All the best

If it's working, then leave it alone!.
