11.7 Upgrading the cabinet unit firmware
When you upgrade the cabinet unit firmware (by installing a new CompactFlash Card with a
new firmware version, for example), you might also have to upgrade the firmware for the
DRIVE-CLiQ components in the cabinet unit.
If the system detects that the firmware in the DRIVE-CLiQ components needs to be updated,
it will trigger this process automatically when the automatic firmware update is performed.
Automatic firmware update sequence
1. During an automatic firmware update, the "RDY" LED on the CU320 Control Unit flashes
slowly (orange, 0.5 Hz).
2. The firmware update is performed automatically and in sequence on the DRIVE-CLiQ
components; during the update process, an LED on the component whose firmware is
being updated will flash slowly (green-red, 0.5 Hz).
3. Once the firmware update on an individual DRIVE-CLiQ component is complete, the LED
on that component will flash quickly (green-red, 2 Hz).
4. Once the firmware update on all components is complete, the LED on the CU320 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 must not be interrupted while the firmware is being
upgraded.
CAUTION
New firmware should only be installed if there is a problem with the cabinet unit.
Problems with the cabinet unit cannot be ruled out after the firmware has been
upgraded.
