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
—RAM: minimum of 256 MB
—BCM1000/BCM400: MSC 1A Media Services Card (MSC) with two
—BCM200: MSC 1B Media Services Card with one or two
—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
—The first character cannot be the dash character
