Radio Software Upgrade
The Aprisa SR radio software can be upgraded simply by plugging a USB flash drive containing the new
software into the USB A host port
on the Aprisa SR front panel.
The software upgrade procedure is different for an Aprisa SR Protected Station (see ‘Protected Station
Software Upgrade’ on page 32).
Note: If a radio has been configured for a Protection Type of ‘Redundant’ (see ‘Terminal > Protection’ on
page 77), and that radio is no longer part of a Protected Station, the Protection Type must be changed to
‘None’ before the radio software upgrade can be achieved.
Upgrade Process
To minimize disruption of link traffic and prevent your radios from being rendered inoperative, please
follow the procedures described in this section together with any additional information or instructions
supplied with the upgrade package.
The radio software must be identical on all radios in the FAN.
To upgrade the Aprisa SR radio software:
1. Check that the SuperVisor USB Upgrade setting is set to ‘Enabled’ (see ‘Maintenance > Upgrade’ on
page 114).
2. Unzip the software release files in to the root directory of a USB flash drive.
3. Power off the Aprisa SR and insert the USB flash drive into the Host Port
.
4. Power on the Aprisa SR.
5. The software upgrade process is complete when the OK LED lights solid orange. This can take about 2
minutes.
The software will have loaded in to the radio Standby SW location.
6. Remove the USB flash drive from the Host Port
.
7. Power cycle the Aprisa SR.
Login in to the radio being upgraded and view the Active and Standby SW version (see ‘ Summary’ on page
If the upgrade process was successful, the Active SW Version will show the new software version and the
Standby SW Version will be shown as ‘No Standby’.
If the upgrade process did not start, the Aprisa SR could already be operating on the version of software
on the USB flash drive. This will be indicated by flashing OK LED and then the OK, DATA and CPU will light
steady green.
