Software Upgrade
A software upgrade can be performed on a single Aprisa SR+ radio or an entire Aprisa SR+ network.
Network Software Upgrade
This process allows customers to upgrade their Aprisa SR+ network from the central base station location
without need for visiting remote sites.
The Software Pack is loaded into the base station with the file transfer process (see ‘Software > File
Transfer’ on page 227) and distributed via the radio link to all remote stations.
When all remote stations receive the Software Pack version, the software can be remotely activated on all
remote stations.
Non-Protected Network Upgrade Process
This upgrade process is for upgrading the software on an entire Aprisa SR+ network from a non-protected
base station. If there are protected remotes in the network, they must be locked to the current active
radio.
To upgrade the entire Aprisa SR+ network software:
1. Using File Transfer, load the software pack into the base station (see ‘Software > File Transfer’ on
page 227). The software can be transferred to the radio via an FTP transfer or from a USB flash drive.
The Aprisa SR+ network file transfer operation is indicated in base station and remote stations by a
flashing orange AUX LED.
2. Distribute the software to the entire network of remote radios (see ‘Software > Remote Distribution’
on page 234). Note that the distribution process over the air will take some time, depending on RF
and Transfer rate settings.
The Aprisa SR+ network software distribution operation is indicated in base station and remote
stations by a flashing orange MODE LED.
Note:
The distribution of software to remote stations does not stop customer traffic from being
transferred. However, due to the volume of traffic, the software distribution process may affect
customer traffic.
Software distribution traffic is classified as ‘management traffic’ but does not use the Ethernet
management priority setting. Software distribution traffic priority has a fixed priority setting of ‘very
low’.
3. Activate the software on the entire network of remote radios (see ‘Software > Remote Activation’ on
page 236).
Note:
When the new software activates on the remote radios, all link communication from the base
station to the remote will be lost. The base station will attempt to re-establish connectivity to the
remote radios for the new version verification but this will fail. However, when the new software
activates on the remote radios, the remote radio will reboot automatically and link communication
will restore when the base station software is activated.
When the Remote Activation process gets to the ‘Remote Radios On New Version’ step, don’t wait for
this to complete but proceed to step 4.
