Configuration and Operation continued

Quick Test

After installing the PDU and connecting equipment, you may test the Automatic Transfer Switch function by temporarily shutting down the UPS system connected to the Primary AC input. When the Primary input UPS is no longer supplying AC power, the PDU will switch from the Primary input to the Secondary input, and the Secondary input LED will illuminate. When the Primary input UPS has been restarted and resumes supplying AC power, the PDU will switch back to the Primary input.

Primary Input Active

Secondary Input Active

Note: The primary and secondary inputs must be connected to separate sources of utility power. The automatic transfer switch function will be compromised if the primary and secondary inputs are connected to the same utility power source. Do not perform a test with equipment that must remain in productive operation. Any test procedure must prepare for the contingency that the equipment may lose power. Do not test the PDU by detaching power cords which are connected to live power sources, as this eliminates the connection to ground and places your equipment at risk.

Enhanced Operation

Installing an SNMP card (the most recent version of model SNMPWEBCARD) in the accessory slot of the PDU allows remote, network-enabled control of the receptacles. With the addition of the SNMP card, the PDU provides precise remote load management, including sequenced power-up, receptacle control, environmental monitoring and automatic load shedding.
