Backup Licenses
If the A3 RF assembly is replaced the licenses that are in the A5 CPU memory
will need to be backed up to the backup storage location in the new A3 RF
assembly so that there will be a copy of them in case the A5 CPU assembly
should ever need replacement.
When an A3 RF assembly is replaced the following error message will be
displayed until the licenses are backed up:
617 Configuration Error: Instrument licenses have not been copied to the
backup storage. Use the service procedure to copy license keys to backup
storage.
The following procedure will backup the instrument licenses from the A5 CPU
assembly memory to the backup memory location on the new A3 RF assembly:
1. Turn the instrument off by using the front panel power button.
2. Once the instrument has turned off press and hold the front panel Preset
key.
3. While holding the Preset key, press and release the power button to turn
the instrument back on.
4. Continue to hold the Preset key for 10 seconds after pressing the power
button, then release it.
5. After approximately 30 seconds the boot Service Menu will appear, as
shown in Figure 3-1.
6. Using the front panel arrow keys scroll down to Start main firmware
service menu and press Select.
7. When the service menu warning screen is displayed press Continue.
8. On the main firmware service menu select Next page until a selection for
Backup license data is available.
9. Select Backup license data as shown in Figure 3-3, and then select Done.
