  • How do I Reset an UPSAC Unison Processor?

    To reset a Unison UPSAC processor, simply reset the Sensor CEM which it resides in (usually Rack #1).

    You also need to reset the Unison LinkPower Supply (ULPSA or ULPSB), which is a wall- or rack-mounted power supply.  It can be identified by a Green and Amber LED on the panel, with a Reset button in between the two LED's.  Make sure to fully depress the ULPSA/ULPSB reset button (use a pen or tweaker).

    The ULPSA/ULPSB should be reset within 30 seconds of the CEM UPSAC.
