if you haven't saved config, then reboot should help also.
otherwise console is your only hope....

there is no option to "Save".
this switch Auto Saves the configuration automaticly.

does anyone here knows if there is any way using the MAC address or hash that as the Password like other vendors has the ability to recover the Admin password?

from_expCommented:
autosave feature can be disabled (if I remember correctly)
however, I would try console first, because without physical access you hardly be able to recover lost password....

Yes but if i am comparing this device to another vendors (Like Cisco for example) i remmember that there is an option to recover lost admin password..
i would like to know if this option is available in Nortel products.

A help will be very appreciated in here...

Thanks in advance

Do you have another privileged password or write community via SNMP?

If you have another baystack, you could try to stack it.
Since the password for stack's and standalone units are different.

This unit configured as a Base one.
and i don't know if snmp is enabled.

This device was configured from default configurations.

Well... Found the Solution:

Default password and default password security
For the non-SSH image, the default password for RO is user and secure
for RW. For the SSH software image, the default password for RO is
userpasswd and securepasswd for RW.
