DPOE™ Power System User Manual Part Number: PN380C
OVERVIEW The DPOE™ Power Patch Panels and the DPOE™ Compact 8 Midspan provide a reliable and cost-
effective solution for Power over Ethernet (PoE) applications, complaint with the IEEE 802.3af-2003
specifications or the alternate PoE (Cisco Legacy) specifications. These DPOE™ Power over Ethernet
Systems allow centralized powering of network devices, such as Voice over Internet Protocol-based
(VoIP) telephones, IP security and surveillance cameras, or wireless access point (WAP) devices, over
the same cabling used to send data. DPOE™ Power over Ethernet Systems fit into 19" racks and occupy
1RU height.
The DPOE™ Power over Ethernet Systems may be powered individually using a DPOE™ Power Supply
(PANDUIT part # DPOEPWRB120Y), which delivers 120 watts at 48 Volts of Direct Current (VDC) to a
single DPOE™ Power Patch Panel or DPOE™ Compact 8 Midspan. However, 120 watts may not be
enough power to support all the Powered Devices (PD) connected to the panel or powered midspan. In
these cases, or in cases of multiple DPOE™ Power over Ethernet Systems, a larger power system is
often required. One option is to use the DPOE™ Power System Chassis with Power Rectifiers, herein
referred to as the DPOE™ Power System.
The DPOE™ Power System uses a modular design to supply power at 48 VDC to DPOE™ Power over
Ethernet Systems. The DPOE™ Power System consists of a chassis (PANDUIT part # DPOEPWRCU),
which can accommodate up to three rectifiers (500 or 1250 watt rectifiers), depending on the current and
future power requirements for the DPOE™ Power over Ethernet Systems being used.

The DPOE™ Power System accepts an Alternating Current Voltage (VAC) between 100 and 240 VAC
(47 to 63 Hz) and produces a regulated output of 42 - 56 VDC capable of delivering a max of 10 Amperes
(A) of Direct Current (DC) in an ambient operating temperature range of -40° Celsius (C) to +70° C per
output channel.
