Part Number: PN380
OVERVIEW
The DPoE
TM
Power Patch Panel (PANDUIT part number DPoE24U1X) provides 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. Each DPoE Power Patch Panel allows
centralized powering of up to 24 devices, such as Internet Protocol-based (IP) telephones, Network
Security Cameras, or Wireless Devices, over the same cabling used to provide the Ethernet connectivity.
Each DPoE Power Patch Panel fits into a 19" rack and occupies 1RU height.
The DPoE Power Patch Panels may be powered individually, such as with the PANDUIT individual power
supply (PANDUIT part number DPoEPWRB120), which delivers 120 watts at 48 Volts of Direct Current
(VDC) to a single DPoE Power Patch Panel. However, 120 watts may not be enough power to support all
the Powered Devices (PD) connected to the panel. In these cases, or in cases of multiple DPoE Power
Patch Panels, a larger power system is often required. One option is to use the PANDUIT DPoE Power
Patch Panel Power System, herein referred to as the DPoE Power System.
The DPoE Power System uses a modular design to supply power at 48 VDC to the DPoE Power Patch
Panel(s). The DPoE Power System consists of a chassis (PANDUIT part number DPoEPWRCU or
DPoEPWRCM), which can accommodate up to 3 rectifiers of either 500 or 1250 watts each, depending
on the current and future power requirements for the DPoE Power Patch Panels. The chassis can be
equipped with an optional Network Interface Card (NIC) (PANDUIT part number DPoEPWRNIC).
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 100 Amperes
(A) of Direct Current (DC) in an ambient operating temperature range of -40° Celsius (C) to +70° C. The
default voltage setting is 54 volts. It can be adjusted through the Element Management System (EMS).
