PGRADE
Note:
For security purposes, we recommend that you disable the TFTP Server after the upgrade
is complete.
To remotely upgrade the system, you are required to have a PC/workstation that is connected to
the system’s network. It must have the following features:
•
TELNET client
•
TFTP client
To perform a remote upgrade, first upgrade to the latest SSB, if required, then upgrade the OSW.
The Release Notes will indicate whether or not the SSB needs to be upgraded.
Note:
If, during a remote upgrade, the compressed file set cannot be uncompressed into the Flash
File System due to a lack of space, the compressed file set will not be deleted from the Flash
File System and the previous version of the OSW will be booted. If the OSW determines
there is a compressed file set (a file suffix of .OSW) in the Flash File System, then the
following message is logged in the system log:
>flash update
WARNING: You are about to restart the system.
You should allow 30 seconds before a system restart occurs.
Do you still wish to restart (Y or N)?
