Upgrading the chassis unit firmware
Updating the device firmware (by installing a new memory card with a new firmware version,
for example), may also make it necessary to update the firmware of the DRIVE-CLiQ
components in the built-in unit.
If the system detects that the firmware in the DRIVE-CLiQ components needs to be
upgraded, it will do this independently as part of the automatic firmware update.
Automatic firmware update sequence
1. During an automatic firmware update, the "RDY" LED on the Control Unit flashes slowly
(orange, 0.5 Hz).
2. The firmware update is performed on each DRIVE-CLiQ component as needed; during
the update process, an LED for the respective component flashes slowly (green/red, 0.5
Hz).
3. Once the firmware update for a specific DRIVE-CLiQ component is complete, the LED for
that component will flash quickly (green/red, 2 Hz).
4. Once the firmware update for all components is complete, the LED for the Control Unit
will flash quickly (orange, 2 Hz).
5. To complete the automatic firmware update process, a POWER ON is required (switch
the device off and back on again).
Note
The power supply to the components should not be interr
upted during the update, because
otherwise the firmware update must be restarted.
