I have never done this before but need to. Is there any gotchas out there or is it pretty simple? For our Nortel PIMG I believe you'll need the ami_v5.1su3? Is this the correct file? Also, how do you backup the config.ini? Is is basic CLI commands from a console connection? Any info would be appreciated?
The best way to upgrade the firmware is fromt GUI.
The process is pretty straight forward. The ami_v5.1su3 is the correct file. Upgrade instructions are included in the zip file.
Go to export to backup the config.ini
Step 5 Click Log On.
Step 6 On the Configure menu, click Upgrade.
Step 7 On the Upgrade page, click Browse.
Step 8 In the Choose File dialog box, browse to the directory on the Windows workstation that has the extracted PIMG firmware update files.
Step 9 Click Ami.app (where is multiple digits), and click Open.
Step 10 On the Upgrade page, click Install.
Step 11 After the file is installed, a message prompting you to restart the PIMG unit appears. Click Cancel.
Caution Do not restart the PIMG unit until you are instructed to do so later in this procedure, even if the file installation fails. Restarting the PIMG unit at this step may prevent the PIMG unit from functioning correctly.
Step 12 Repeat Step 6 through Step 11 for each of the following files:
Step 13 On the Configure menu, click Upgrade.
