Chapter 15 Upgrading or reinstalling the software 761

Nortel Secure Network Access Switch 4050 User Guide

When you have downloaded the software upgrade package, you can inspect its 
status with the 

 command.

At the 

Software Management# prompt, enter the following command:

The downloaded software upgrade package is indicated with the status 
unpacked. The software versions can be marked with one out of four 
possible status values. The meaning of these status values are:

—

unpacked means that the software upgrade package has been 
downloaded and automatically decompressed.

—

permanent means that the software is operational and will survive a 
reboot of the system.

—

old means the software version has been permanent but is not currently 
operational. If a software version marked old is available, it is possible to 
switch back to this version by activating it again.

—

current means that a software version marked as old or unpacked has 
been activated. As soon as the system has performed the necessary health 
checks, the current status changes to permanent.

To activate the unpacked software upgrade package, use the 

 command.
