4550T Firmware Upgrade

Two files are required:

• The 'Diagnostic' image: 4500_53003_diag.bin
• The 'Agent code' image: 4000_573031s.img

There is no requirement to update the bootloader (boot.bin) image.
This upgrade may change the switch branding from Nortel to Avaya.

Connections:

• Upgrading via USB: Connect a USB thumb-drive with the two image files to the front panel USB port.
• Upgrading via TFTP: Connect a TFTP server via Ethernet cable to port 1 (the switch must have an IP address)
• Connect a Serial cable to the front panel Console port, set a PuTTY (or Serial for OSX) to: 9600 8-N-1

Check the current version:

• Power up the switch! At the Avaya logo (or Nortel), you'll see the FW and SW version numbers displayed.
• OR, enter Ctrl-Y to activate a session, followed by en, followed by show sys-info

Always upgrade the DIAG first, then the IMAGE.

DIAG (FW) Upgrade:

• From the console, Ctrl-Y, en <enter> (enable)
• Via USB:  download usb diag 4500_53003_diag.bin
  Via TFTP: download address x.x.x.x diag 4500_53003_diag.bin
• Firmware will upgrade and switch/stack will reboot.

IMAGE (SW) Upgrade:

• From the console, Ctrl-Y, en <enter> (enable)
• Via USB:  download usb image 4000_573031s.img
  Via TFTP: download address x.x.x.x image 4000_573031s.img
• Software will upgrade and switch/stack will reboot, upgrade, and reboot again.

After the switch reboots, check the splash screen to ensure the Firmware and Software has been updated to the correct version.
IMPORTANT: A stack will take a little longer to initialise. Wait for the splash screen to refresh a second time, indicating its done.

Note: Firmware upgrade via TELNET requires a TFTP server (eg: SolarWinds or PumpKIN) hosting the two image files.
A TFTP server on the ELAN is highly recommended to assist with soft/firm/load-ware updates and configuration backups.
