NBX Licensing 77
Devices introduced at R5.0 or higher will not be recognized.
Group Licensing, 3105 Attendant Consoles, and R4.X Software
If you reboot to R4.4 or R4.3, Group 2 licenses are converted to 3102
device licenses, which means that a 3105 Attendant Console, which is a
Group 2 device, could become unavailable. The following examples show
what happens to 3105 Attendant Consoles when you reboot to R4.4 or
R4.3.
Example 1: Your system is running R4.3 (or R4.4) software. The system
has one 3105 Attendant Console installed and you have one 3105 device
license installed on the system. You upgrade the system. The 3105 device
license becomes a Group 2 license and the 3105 continues to operate.
You reboot the system to R4.3 or R4.4 and the 3105 continues to operate
under the original 3105 device license.
Example 2: Your system is running R4.3 (or R4.4) software. The system has
one 3105 Attendant Console installed and you have one 3105 device
license installed on the system. You upgrade the system software, and then
add another 3105 and a Group 2 license. You reboot the system to R4.3 or
R4.4. One of the 3105 Attendant Consoles continues to work and the other
does not because the Group 2 license that was used by the 3105 while
operating after the upgrade is converted to a 3102 device license. To enable
the 3105 under R4.4 or R4.3, you need to add a 3105 device license.
Example 3: Your system is running R4.3 (or R4.4) software. The system
has one 3105 Attendant Console installed and you have two 3105 device
licenses installed on the system. You upgrade the system software, and
then add another 3105 and a Group 2 license. You reboot the system to
R4.3 or R4.4. Both 3105s continues to work.
