Avaya/Nortel 4550T switch issues

[Qrilock]

Does anyone have any experience with these?
My company has deployed s number of these switches in standalone and stacked configuration, and we are having some issues.

One of our problems is all the devices on a switch in a stack lose connectivity. Turns out one of the slave switches is rebooting, but we can't find the reason. Show sys-info only shows the info for unit 1. This is in a remote location, so I can't easily console into unit 2. Any ideas for getting the last reboot reason for unit 2?

We have also seen these lose their VLAN config after a power failure. Avaya is not being much help.

Any help at this point would be greatly appreciated.

is the slave switch powered from the same circuit as the others? not sure if that switch has any crash dump functionality. you could always have someone console the switch to a local server or laptop and gather the output.

do you have active support coverage? if all else fails, escalate or RMA it.

Avaya support has not been much help. Our local Avaya CAM came in today and I got to tell him all the issues we have had with these things. He is going ot go look back at all of the support tickets we have had on these things, and the RMA's already done, and hopefully get someone out here to fix these things.
I have just about come to the conclusion that these are little more than orangutang shit in a box.

I've used some in the past, and while not in any great capacity, I can say that my limited experience with them was less than stellar. Issues like you explain and other weirdness abound. If possible I would look into replacing these and or upgrading the code.

I want to replace them. These should never have been deployed. To make it (somewhat) worse in my opinion, this is actually a deployment for a customer. My company sold these pieces of crap when we put a in new phone system. Customer is very unhappy at this point, and wants to displace them with Cisco gear. I hope we can do that..
