    Nortel - Avaya 5510 Switch Firmware

    Biv343, I hope you see this message... The 4.2.1. worked however after updating I still cannot update to 5.1.0 - am I missing another release? If so, do you happen to have a copy?

    Hello, Does anyone have a link to baystack 5510 - 4.2.1 firmware? I have all the newer firmware but I need 4.2.1 to update an older switch to the new version. Thanks, Jacob
