1. Introduction
Power-over-Ethernet (PoE) eliminates the need to run 110/220 VAC power to other
devices on a wired LAN. Using Power-over-Ethernet system installers need to run only
a single CAT5 Ethernet cable that carries both power and data to each device. This
allows greater flexibility in the locating of network devices and significantly decreasing
installation costs in many cases.
There are two system components in PoE -- the Power Sourcing Equipment (PSE)
initiates the connection to the second component, the Powered Device (PD). The
current is transmitted over two of the four twisted pairs of wires in a Category-5 cable.
Power over Ethernet follows the IEEE 802.3af and is completely compatible with
existing Ethernet switches and networked devices. Because the Power Sourcing
Equipment (PSE) tests whether a networked device is PoE-capable, power is never
transmitted unless a Powered Device is at other end of the cable. It also continues to
monitor the channel. If the Powered Device does not draw a minimum current,
because it has been unplugged or physically turned off, the PSE shuts down the power
to that port. Optionally, the standard permits Powered Devices to signal to the PSEs
exactly how much power they need.

2. Hardware Description
This Section mainly describes the hardware of the POH-0850TX, and gives a physical
and functional overview.
PhysicalDimension
The 8-port Power over Ethernet Hub physical dimension is: 440mm x 224mm x 44mm
(Lx W x H)
FrontPanel
The Front Panel of the POH-0850TX consists of 8x RJ-45 Ethernet ports, LED
indicators, and one console port.

LEDIndicators
The LED Indicators gives real-time information of systematic operation status. The
following table provides descriptions of LED status and their meaning.

Figure 2-2. LED indicators
LED Status Color Description
On Green Power is transmitting to the device
Power
Forwarding Off --
Power is not transmitting to the
device
On Orange Device is overload or short.
Off -- Device attached.
Power Off
Blinking Orange Detecting the device
Table 2-1. The Description of LED Indicators
Notice
The “Power Off” LED is flashing when No PD attached.
And the LED goes off when PD attached. The corresponding “power forwarding” LED will then
go ON or OFF depending on switch action.
RearPanel
The 3-pronged power plug, 2 Ventilation fan and on/off switching are located at the
rear panel of the 8 port Power over Ethernet Hub. The device will work with AC in the
range 100-240V AC, 50-60Hz.
Figure 2-3 Rear panel of the POH-0850TX
PowerOn
Connect the power cord to the power socket on the rear panel of the Switch. The other
5
side of power cord connects to the power outlet. The internal power supply of the
Switch works with voltage range of AC in the 100-240VAC, frequency 50~60Hz. Check
the power indicator on the front panel to see if power is properly supplied.
NetworkApplication
The Power over Ethernet Hub can provides power to the PD that follow the IEEE
802.3af standard in the network. It can solve the problem of position limitation. The
network device can be installed in more appropriate position for better performance.
The following figure is an example of network application for Power over Ethernet Hub.
