Here’s another one that I’ve personally seen and I think folks need to hear about. Nortel has just revised this technical bulletin that was originally released in March 2008 concerning issues with their 8692SF (CPU) for the ERS 8600 chassis and the new 8005AC power supplies for that chassis. If you have non-E, E, or M cards in your ERS 8600 chassis with an 8692SF and 8005AC power supply you should check the hardware version of the 8692SF.
Unfortunately the bulletin makes reference to December31, 2008 as the expiration of the replacement program for folks that don’t have a support contract.
You would never expect a switch to not initialize properly on a hardware reboot would you? That’s exactly what can happen and I’ve seen the problem on a number of occasions since we upgraded all our core ERS 8600 switches about two years ago with 8005AC power supplies to support the new R modules.
