SMC software upgrades

553-3001-225 Standard 1.00
Maintenance
The SMC software can be upgraded using the following methods:
• Package upgrade: Using the CLI or Web UI (preferred), a single file is
pushed to the SMC, unpacked, and then activated by an automated
reboot. This is the recommended upgrade process. The package upgrade
retains the current SMC configuration. The SMC can hold two package
files on the system, so you can revert back to the original if required.
• Image upgrade: Using the CLI, a single file is loaded from CD-ROM
(ISO install CD) or via FTP/TFTP to the SMC. The file is then unpacked
and activated. This upgrade process DOES NOT retain the current
configuration, so the configuration must be saved prior to the upgrade.
Use this upgrade when there is concern that the SMC application
software may be corrupt but the Operating System is intact.
• ISO install CD: Using the CLI, the SMC is booted with the Install
CD-ROM. The hard drive on the SMC is reformatted and all software is
reinstalled. The configuration must be saved prior to the ISO install
because the configuration is lost during the install. This process is used
to restore the SMC to the factory default state.
The upgrade files are provided on the Nortel web site. The package files have
a .PKG extension, and the ISO Install CD has an .ISO extension.
Nortel recommends that you perform software upgrades during a
maintenance window since the upgrade can impact service.
