Upgrading to Release 4.1
Performing a Remote Upgrade Using FTP and Telnet
You can upgrade your CVX switch to Release 4.1 remotely using FTP and Telnet.
At the completion of the upgrade, the CVX switch uses the same configuration
parameters as it did before the upgrade by retaining the previous config.cvx file
and the previous boot.ini file.
Before you upgrade the CVX switch, be sure you have the following CVX switch
information:
• IP address
• User name
• Password
To upgrade the CVX switch remotely, perform the following steps:
Note: Before upgrading the CVX switch to Release 4.1, be sure to save a
copy of all the contents of the 2.0, 3.0, 3.1, 3.6, or 4.0 Nortel-supplied
flash card, either to a laptop PC or a network drive. This step will allow
you to restore your previous configuration if you experience problems
with the 4.1 upgrade. If the CVX switch is being upgraded from Release
3.6 or later, the Backup and Revert commands may be used to save the
current load to a sub-directory of the flash card. See the CVX
Multi-Service Access Switch Administrator’s Guide for more information.
Note: Before upgrading the CVX switch with a redundant SCC, ensure
that the primary SCC is running in the primary SCC slot. If it is not
running, do not proceed with the upgrade procedures until you perform a
failover from the secondary slot to the primary.
