BCM50 reset

BCM50 reset

BCM50 reset

Just got a BCM50 rel 5.0 and customer does not know nnadmin password.
Some IT person changed it a last location and left with the info.

What is the procedure to reset password.

I know data will be lost.

RE: BCM50 reset

You need to use the reset button and follow a set sequence to default the BCM 50 system. You will also need to have the keycodes. Make sure you have them before you do it or try and find if you have a recent backup available.

RE: BCM50 reset

Just a thought, have you tried both Ethernet ports?. Can you followed this guide to check that the LAN1 port is the correct IP address?.


Have you tried browsing via windows internet explorer to see if you get the account login screen?.

Use this link to find out how to reset your BCM back to default.


Go to page 32 to carry out a Level 1 or 2 reset.

                   Reset levels

Reset to factory settings is a stand-alone feature that has the following levels of reset:

• Level 1 reset erases all customer-specific data and restores the default configuration for all
components. This reset leaves the software components untouched. That is, the system has the
latest release and patch level of the software installed. Only the system and user configuration
data is erased and replaced with default values. No Ethernet connectivity to the system occurs
during this operation.

• Level 2 reset erases all customer and system configuration data and all software releases and
patches. This reset re-installs the original factory configuration settings. Level 2 reset also
resets the router firmware to what was shipped from the factory. No Ethernet connectivity to
the system occurs during this operation

RE: BCM50 reset

Turns out that this release cannot be reset as per manual. You have to go Avaya support for reset.

Bonfire material.

RE: BCM50 reset

Starting with release 5, you need the nnadmin's account password to initiate the L1/L2 reset. You can also contact Avaya support to use the nnsupport account to initiate the reset. You don't have the nnadmin password, so the proper way to deal with it would be to contact Avaya.

If you don't want to contact Avaya for some reason, you need to do two things:
a) Recover the current license file from the system (if you have a copy of the license file for the system, you can skip this step)
b) Reset the hard disk to the factory image

To recover the license file, you'd have to take the hard disk out of the BCM, mount it under some Linux distro and copy the license file from the hard disk.

To reset the hard disk, you can use a BCM50 R3 or earlier system, put the hard disk into the chassis and invoke the reset procedure according to the manual. Another option is to use a new FRU hard disk. You could also clone the hard disk image from another R5 system (with a known nnadmin password) to the hard disk from the system with the unknown password.

Once the hard disk is reset, you just need to apply the license file and the BCM should be usable again.

RE: BCM50 reset

Hey ucx,

Any hint where the .lic might be on the drive.  I've cracked open my BCM50r5 and can't find it.  There are a lot of partitons and directories in there.

RE: BCM50 reset

Hi there!

If you have the BCM hard drive under your Linux as let's say the device /dev/sdb, you should mount the third partition (/dev/sdb3), go to the directory nn/etc and copy the file licensefile.txt to your system.  After copying it, you could rename it to the original license file name that is <systemid>.lic.

Good luck!

RE: BCM50 reset

Actually, one note - I believe that on BCM50 R5 and newer systems the license file is stored in the directory I mentioned and also in the EPROM. You should be able to replace the hard drive, boot the system and the BCM50 software should recover the license file automatically.

RE: BCM50 reset

I actually considered that I could just put a fresh copy on there.  However I don't have another r5 image.  Only r2, r3, and r6.  :-/

I went through the /nn/etc directory and didn't see it.  Is there a way to edit a config file on the drive that triggers an L2 reset?  I'm also missing the PW for this unit!
