Restarting system.
login:

Note: Activating the unpacked software upgrade package may cause the command line interface (CLI) software to be upgraded as well. Therefore, you will be logged out of the system, and will have to log in again. Wait until the login prompt appears. This may take up to two minutes, depending on your type of hardware platform and whether the system reboots.

6Log in again and verify the new software version:

>> Main# boot/software/cur		Status
Version	Name
-------	----	------
x.x	NSNAS	permanent
z.z	NSNAS	old

In this example, version x.x is now operational and will survive a reboot of the system, while the software version previously indicated as permanent is marked as old.

Note: If you encounter serious problems while running the new software version, you can revert to the previous software version (now indicated as old). To do this, activate the software version indicated as old. When you log in again after having activated the old software version, its status is indicated as current for a short while. After about one minute, when the system has performed the necessary health checks, the current status is changed to permanent.
