default.
• Both the Main and Backup Power will
automatically detect whether the power
source is 110 or 230VAC.

Connect the Main Power to your
primary power grid.
Connect the Backup Power to a
secondary power grid or an
Uninterruptable Power Supply (UPS)
Tip: Intel recommends that you
connect the Main and Backup Power
connectors to different power
sources to ensure maximum
redundancy. See the next page for
levels of redundancy.
Check the LEDs
• The RPS status LED on the RPS should be
solid green for all supplies.
• The Device status LED on the RPS should
be solid green for each connected device.
• The RPS LED on the device should be
solid green.
• The Power LED on the RPS should be
solid green if you connected to both
the Main and Backup Power. If you
connected to the Main only, the LED
remains red.
Note: The RPS is meant to function as a
backup power source. Do not power the
device using the RPS unless the device’s
power supply fails.
