    How to configure Multiple D7038, DS9484 NAC Power Supplies

    Issue

    When AC power is lost on all 6 - D7038's it causes NAC1 on the D7024 that is driving the inputs of the D7038's to go into trouble. What is causing this to happen?

    Solution

    The AC dipswitches 2 & 3 on the D7038's all had different settings.  In order for the AC Delay feature to work, all the AC dipswitches 2 & 3 need to be set for the same value.

    Note: In order for Dip Switch Changes to take effect the D7038 needs to be powered down completely for 4 minutes.
