Upgrade Software Nortel ERS 8600

Here’s a question that I’ve been asked over and over again.

How can I upgrade the software of a Nortel ERS 8600 Switch?

It’s actually very easy and only takes a few minutes (along with a reboot). If you have dual CPUs (8690SF, 8691SF, 8692SF) your going to need to upgrade both CPUs.
