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 or from a USB flash drive.
1. Using the Hardware Manual Lock switch (see ‘Hardware Manual Lock’ on page 330), or the Software
Manual Lock (see ‘Lock Active To’ on page 285), 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 303).
3. Confirm that the transfer is successful (see ‘Protected Station: Software > Manager’ on page 306).
4. Using the Hardware Manual Lock switch (see ‘Hardware Manual Lock’ on page 330), or the Software
Manual Lock (see ‘Lock Active To’ on page 285), 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 300).
6. Confirm that the transfer is successful (see ‘Protected Station: Software > Manager’ on page 306).
7. Distribute the software to the entire network of remote radios (see ‘Protected Station: Software >
Remote Distribution’ on page 308). 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 311).
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 stations will re-register with the base station. The
remote stations software version can verified with ‘Network Status > Network Table’ on page 259.
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 >
5. Immediately after that, activate the new version software pack of the primary radio (see ‘Protected
Station: Software > Manager’ on page 306).
Note that the activation process will take a few minutes.
