MICS power failed, all "Avaya" labelled sets didn't come back up

[phoneauthority]

Hello, we have a client with an MICS running 7.1xc software.

They had a power failure overnight and the UPS also ran out of power.

Client only has T7316 E phones, some of which are newer and say "AVAYA" on them, and some of which are older, and say "Nortel Networks" on them.

When things came back up after the power outage, everything was perfectly fine, except for the 28 newest phones, all of which say "AVAYA" on them.

The 75 or so older phones, which say "Nortel Networks" on them, all came back up no problem.

The sets were all placed randomly, so the Avaya sets are not all on specific 0x16s, they are just random across the business.

Customer has 8 x 0x16s plus the 0x32.

They called us in - all we had to do was unplug the Avaya sets from their outlet and then plug them in (to make them reboot), then they all came back up no problem.

But I am trying to figure out why the Avaya branded phones didn't come up after the power outage, but the Nortel ones did.

Very strange.

Thanks for any advice or ideas.

I'd guess the Avaya branded phones have different firmware. I have no idea why none of them would come up after a power outage.

That is very interesting, sensitive sets in some way to power fluctuations?.

I would be interested to know exactly what happened as in did the UPS die just as the power came on, what brand UPS is used and its condition.

I would like to believe that if the UPS was not there and that the system was without power for a minute then power applied cleanly that all would have been fine.

Example in a brown out (when power drops and comes back right away) weird things usually do happen then you have to reboot your system/PC etc for a clean proper reboot.
