Nortel ERS 5520 Firmware(s)
« on: May 23, 2013, 05:05:02 AM »
Hi
im trying to upgrade my Nortel ers 5520 switches from 4.2.0.13 firmware to 6.2.3.0. I have been able find a copy of the 6.2.3.0 firmware however i beleive that i can not upgrade directly and have to use an intermediate firmware like 5.1.1. I can't get the firmware directly from avaya, so i was wondering if anyone would be able to send me a 5.x firmware to upgrade to.

thanks
alex

You'll need at least 6.0.0 firmware in addition - all 6.x upgrades have to go through this.

Suggestion: pry open the wallet and get basic maintenance on your switch.  I don't think it is that expensive for minimal coverage to at least get code and online support.

The rough upgrade sequence would be 4.2 > 5.0 > 5.1 > 6.0 > 6.2 > 6.3.1 to get you to the latest code safely.
