ARN Password Reset Fail


I have follow the below step and still fail.

connect to the ARN console port with a console cable
then power cycle the router
when the ARN begins running diagnostics, press the Ctrl+C followed by an ENTER (that's key!) This will bring you to a diagnostics prompt.

Now, enter the following command to clear the Manager password from NVRAM
    diag_1>> d/l/n:5 410000 0

reboot the router normally
loging and reset the Manager password

I have tested on 6 ARN router, is there any other thing that I might miss up.


RE: ARN Password Reset Fail

Hello, i found this in the nortel primus web:
Could it be that you´ve typed a "I" instead of an "l"???


3.At this prompt, type in the following command exactly:

d/l/n:5 410000 0

This sequence will blank out the Manager password in NVRAM.

4.Type boot or power cycle the ARN. There is no longer a Manager password.

Cheers Michael
