I have purchased some used Avaya Ethernet Routing Switch 4850GTS-PWR+, however they are on:
HW:12 FW:5.6.0.18 SW:v5.6.3.024 BN:24
I need the software image for 5.6.5 or 5.7 and diagnostic image 5.8.0.01 or 5.8.0.03
then I can download the rest from Extreme networks site and update to the latest version, unless it is possible to update straight to 5.9 but the available documentation does not indicate you can do that. The avaya site is locked down so can't download anything. Any help would be greatly appreciated.
