POWER OVER ETHERNET
Installation Guide
1. Introduction
T o achieve best performance of a Wireless LAN, the location of
Access Point (AP) must be carefully chosen. In most cases, finding
a power supply for AP is a common obstacle. Power over Ethernet
(PoE) technology provides the ideal power solution to help
overcome these obstacles.
In Ethernet, four pairs of C5 or C5E twisted pairs are used as
the medium for transmission. The actual data transmission,
however, only takes up two pairs of wires (pairs 1-2 and 3-6). PoE
technology utilizes the remaining pairs (pairs 4-5 and 7-8) to
conduct electricity.
2. Function
Power Sourcing Equipment (PSE) transforms AC to DC. It has a
maximum output power of 16W, fluctuation of 60mV with a
tolerance of ±3%. When it overflows, overloads, short-circuits, or
overheats, the PSE automatically turns off the power , and restarts
after these problems are removed.
PSE applies single chip control management and uses
compatible programs. Technical parameters are as follows:
1. This device complies with IEEE 802.3af
2. When PSE detects that it connects to a device which uses no
electricity, the power supply will be turned off automatically.
3. PSE monitors circuit status at all times. Once it detects that it
connects to an electronic device that has a range between 1-16W ,
it automatically provides electricity to it. When it is lower than 1W,
electricity will not be supplied.
4. PSE protects circuits from problems such as short-circuit,
overload, and electricity receiving device damage by turning off
the power once a problem occurs. Normal power supply will be
resumed once these problems are eliminated.

during the use. To avoid damages to safety device inside the
equipment, non-professional personnel should not take apart
the equipment at any time.
