No longer supported: A number of BCM 3.6/3.7 features are no longer supported in 
BCM 4.0. Refer to 
 for more 
information.
Pre-upgrade tasks
The pre-upgrade tasks must be completed before attempting the upgrade.
The pre-upgrade tasks are divided into three parts:
BCM system tasks
The Upgrade Wizard verifies many of these system tasks during the initial stage of the upgrade 
process. However, if you manually verify these requirements, you can avoid any potential issues 
during the upgrade process.
Perform the following tasks dealing with your BCM 3.6/3.7 system before beginning the upgrade:
Verify hardware requirements: Ensure that your BCM system meets the following 
requirements:
— BCM system running BCM 3.6 (2.2c or 3.1a), BCM 3.7 (2.4f), or SRG 1.0
— Hard disk: must be a Nortel-supplied OEM hard disk (minimum 20GB) with partitions 
defined at manufacture or by the BCM Imaging Tool (BIT)
— RAM: minimum of 256 MB
— BCM1000/BCM400: MSC 1A Media Services Card (MSC) with two MS-PEC IIIs or four 
MS-PEC IIIs
— BCM200: MSC 1B Media Services Card with one or two MS-PEC IIIs installed
— Optional: USB cable to connect the UPS for graceful shutdown (replaces serial 
connection)
Ensure that your system name follows the naming standards: The standards for creating a 
valid BCM 4.0 system name are different than those for BCM 3.6/3.7. If your system name 
does not meet the standards for BCM 4.0, the upgrade will still complete successfully. 
However, Nortel recommends that you change your system name to follow the BCM 4.0 
naming standards (either before or after the upgrade). Please use the following standards when 
determining a system name:
— The system name cannot be blank.
— The system name cannot be greater than 24 characters in length.
— The valid characters are uppercase and lowercase letters (a–z, A–Z), numeric digits (0–9), 
and the dash character (-).
— The first character cannot be the dash character (“-”).
