Overview
PDU monitoring unit
This connection provides the input power for the PDU monitoring unit. The power is supplied by the monitoring unit circuit breaker on the front of the PDU. If the panel is on, and the monitoring unit circuit breaker is closed, the monitoring unit is powered.
Connectspower. to sensors monitoring values such as voltage, current, and
Digital input sensing for monitoring such as circuit breaker status, transformer temperature, fans, etc.
The Display port
The Power LED indicates wether the monitoring unit is receiving power from the AC output of the UPS. If the UPS is powered off, the LED remains
Use the Console port
EPO DIP switches configure the EPO input for the type of EPO switch that is
When the EPO Arm/Test rocker is in the Test position, engaging the EPO switch will not cause the load to be powered off. When the rocker is in the Armed position, engaging the EPO switch will cause the PDU’s Main Input switch and the Symmetra PX UPS to be switched OFF. See “Testing the EPO wiring and switches” on page 60 for more information on testing the EPO switch.
The EPO Armed LED is green when the rocker is in the Armed position. The LED is dark when the rocker is in the Test position.
The EPO Tripped LED is red when the EPO switch is engaged (the EPO button is pressed), regardless of the state of the EPO Arm/Test rocker.

The Reset button resets the network processor; it does not reset the PDU or the PDU monitoring unit.
Connect to the InfraStruXure Manager through the network port.
The To UPS port connects the PDU monitoring unit to the Maintenance Bypass/PCB board and the EPO board inside the Symmetra PX UPS. This port is connected to wire harnesses secured inside the PDU that are connected to the Symmetra PX UPS during installation of the system.
The optional User/EPO Contacts port is connected to wire harnesses that connect to the User Connection Plate in the roof (or floor) of the PDU. The port allows for relay outputs (4), input contacts (4), and an EPO input (1). See “How to connect contacts to the PDU monitoring unit” on page 20 and “Testing the EPO wiring and switches” on page 60 for more information.
