The serial number
Introduction
The implementation of changing serial numbers through
keycode was introduced in MM11. Besides the added
security it provides, this feature allows operators to change
their serial number to match the 11-digit serial number of
switches. This means you are now only required to maintain
one serial number for your Nortel products.
Changing serial
numbers through the
menu
There are two ways to change serial numbers from the
System Installation and Modification menus:
• through comprehensive upgrade by entering a new serial
number keycode when prompted.
• from the System Operation Utility menu, through the
selection of the Change System Serial Number option.
(For the procedure, see Chapter 12, “Change system
serial number”.)
Note: The serial number keycode is provided by Nortel on
request.
When to use your
serial number keycode
The following conditions apply to the serial number keycode:
• The serial number keycode cannot be used to perform a
comprehensive upgrade or software installation (that is,
to add features, languages, hardware, or storage
capacity; to convert; or do a platform migration).
• The keycode can only be used on the system for which it
is intended.
System identification
System operations (software installation, comprehensive
upgrade) that require keycode information check to see if the
serial number on the system is the same as the one defined in
the keycode. In these cases, the user is not prompted for the
serial number.
Note: In the case of MSMs, the serial number is always
prompted for.
