Aprisa SRi User Manual 1.1.0
USB Boot Upgrade Method
A single Aprisa SRi radio can also be upgraded simply by plugging a USB flash drive containing the new
software into the USB A host port
on the Aprisa SRi front panel and power cycling the radio.
To upgrade the Aprisa SRi radio software:
1. Unzip the software release files in to the root directory of a USB flash drive.
2. Check that the SuperVisor USB Boot Upgrade setting is set to
‘
Load and Activate
’
(see
on page 259) if you require the new software to load and automatically activate following the radio
power cycle on step 7.
3. Power off the Aprisa SRi and insert the USB flash drive into the host port
.
4. Power on the Aprisa SRi.
5. The software upgrade process is complete when the OK LED flashes green. This can take about 2
minutes.
The software will have loaded in to the radio current software version.
6. Remove the USB flash drive from the host port
.
7. Power cycle the Aprisa SRi.
Login to the radio being upgraded and
go to SuperVisor ‘
The version of the uploaded software will be displayed in the Software Pack ‘Version’ field
and the current
software version.
If the upgrade process did not start, the Aprisa SRi 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, MODE and AUX will light
steady green.
If the radio is not operating on the new software (after the power cycle), it could be caused by the SuperVisor
‘
USB Boot Upgrade
’
setting set to
‘
Load Only
’
(see
on page 259).
In this case, go to SuperVisor see
on page 264 and tick the Software Pack
‘
Activate
’
checkbox and click
‘
Apply
’
.
If any Display Panel LED flashes red or is steady red during the upgrade process, it indicates that the upgrade
has failed. This could be caused by incorrect files on the USB flash drive or a radio hardware failure.
Software Downgrade
Radio software can also be downgraded if required. This may be required if a new radio is purchased for an
existing network which is operating on an earlier software release.
The downgrade process is the same as the upgrade process.
