Software Upgrade 333
If you decide not to install the R4.2 license key, you can click the Reboot
button and select a different release.
Upgrading From R4.1.15 and Later Versions
If you are running R4.1.15 or a later release of R4.1, you can enter the
R4.2 license key and then upgrade. When you enter the license key, the
NBX system software accepts the license key as valid for an unknown
feature. When you upgrade and reboot to R4.2, the license for R4.2 takes
effect.
Upgrading From Release 4.2
In the future, if you are running R4.2 and you upgrade to a new NBX
software version, the final step is to reboot the NBX system specifying the
new release. At that time, the NBX software verifies that you have the
proper license installed. If you have installed the license prior to the
reboot, the upgrade is completed.
If you have not installed the correct license prior to the reboot phase of
the upgrade, the NBX system provides a warning message and guidance
on the appropriate action for you to take.

NBX system remains operational with these restrictions:

■ Voice mail messages are not allowed.
■ The Automated Attendant software is not operational.
■ The ability to configure user groups and Automated Attendants from
a telephone is not operational.
■ If you connect a PC to the NBX system COM1 port using a terminal

sends a message to the Hyperterm application indicating that a
required software license has not been installed.
