8300 Silent Reset Issue

[edslopes]

Dears,

One of our major customers is facing the "silent reset" issue on a 8310 Chassis.
I´ve been searching for this issue and i found that is an unresolved problem. Is there Any workaround to solve this?

I found this on a release notes document:

Under what has been labeled the “silent reset” condition, the
switch switches over to standby SF with nothing in the system log to
indicate why. This generally causes a 45 second to 1 or 2 minute outage
for devices connected to this switch, in non-SMLT configurations. This
situation has a repetitive time frame generally measured in months.

Best Regards

I'm really not that familiar with the ERS 8300 switch.

There are no logs on the PCMCIA card or FLASH filesystem that indicate anything?

The logs on the standby SF/CPU should at least show the switch booting up with the modules/cards being reset and brought online. You might want to attach a PC to the SF/CPU console port to see if there is anything hitting the console port at the time of the event. You'll need to leave the PC connected and "saving" the serial output until the next event but it might give you an idea of what's happening.

If you have a maintenance contract with Nortel/Avaya I would urge you to open a case.

Good Luck!

As of the 4.2.2.0 release notes for the ERS8300 the 'silent reset' problem is not resolved, but there is further debug images (non-GA) available:

From the 4.2.2.0 release notes:
"Any user, who wishes to be a candidate for this deeper (non-GA) debug image, should contact Avaya through their normal support channels. The use of this more advanced debug code requires a system with 256M of memory if using an 8393 SF/CPU. [Q01978449]"

I'm curious if the silent reset is happening to your customer's 8393SF CPUs that only have 128mb or is it happening with 8393SFs with 256mb memory?
