Protected Network Upgrade Process
This upgrade process is for upgrading the software on an entire Aprisa SR+ network from a protected base
station. This software upgrade can be achieved without disruption to traffic.
Transferring the new software to the radios
The software can be transferred to the radio via an FTP transfer, HTTP transfer or from a USB flash drive.
1. Using the Hardware Manual Lock switch (see ‘Hardware Manual Lock’ on page 411), or the Software
Manual Lock (see ‘Lock Active To’ on page 362), force the secondary radio to active
2. Using File Transfer, load the software pack into the secondary radio (see ‘Protected Station: Software
> Secondary File Transfer’ on page 378).
3. Confirm that the transfer is successful (see ‘Protected Station: Software > Manager’ on page 381).
4. Using the Hardware Manual Lock switch (see ‘Hardware Manual Lock’ on page 411), or the Software
Manual Lock (see ‘Lock Active To’ on page 362), force the primary radio to active.
5. Using File Transfer, load the software pack into the primary radio (see ‘Protected Station: Software >
Primary File Transfer’ on page 375).
6. Confirm that the transfer is successful (see ‘Protected Station: Software > Manager’ on page 381).
7. Distribute the software to the entire network of remote radios (see ‘Protected Station: Software >
Remote Distribution’ on page 383). If there are protected remotes in the network, they must be locked
to the current active radio.
Note that the distribution process over the air will take some time, depending on RF and Transfer rate
settings.
Activating the new software on the radios
1. Activate the software on the entire network of remote radios (see ‘Protected Station: Software >
Remote Activation’ on page 386).
2. Monitor the progress of the activation process until the stage where activation of all remote radios has
been confirmed.
When the new software has been activated, remote radios will re-register with the base station. The
remote radios software version can verified with ‘Network Status > Network Table’ on page 331.
3. If the new software version is not over the air compatible with the version currently operating on the
radio, there is no need to wait as all link communication from the base station to the remote will be
lost so the verification of the new version on the remote radio will fail.
4. Activate the new version software pack of the secondary radio (see ‘Protected Station: Software >
Manager’ on page 381).
5. Immediately after that, activate the new version software pack of the primary radio (see ‘Protected
Station: Software > Manager’ on page 381).
Note that the activation process will take a few minutes.
