CBSs report failure to upgrade after all attempts, power cycle the target
CBS units. The user may manually power cycle the CBSs or initiate a
soft reboot.
Manual Power Cycle

from the AC source. Reconnect each power supply starting with the
power supply connected to the primary CBS. Continue
reconnecting each power supply.
Soft Reboot
To initiate a soft reboot, from a command prompt, type
dnCBSreset. It takes a few minutes to reset the CBSs and
complete the firmware update.

dnCBSFirmware
From a command line prompt, type
dnCBSFirwmare to display
the ARM version (firmware version level) for each CBS in the
RealPrice system.
