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.

Physical Dimension

The 8-port Power over Ethernet Hub physical dimension is: 440mm x 224mm x 44mm

(Lx W x H)

Front Panel

The Front Panel of the POH-0850TX consists of 8x RJ-45 Ethernet ports, LED

indicators, and one console port.

LED Indicators

The LED Indicators gives real-time information of systematic operation status. The

following table provides descriptions of LED status and their meaning.

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.

Rear Panel

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.

Power On

Connect the power cord to the power socket on the rear panel of the Switch. The other

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.

Network Application

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.
