Introduction
Power over Ethernet (PoE) eliminates the need to run DC power to other devices on 
a wired LAN. Using a Power-over-Ethernet system, installers only need to run a single 
Category 5 Ethernet cable that carries both power and data to each devices. This reduce 
equipment and installation cost significantly and allows much more flexibility in locating 
a network devices.
There are two system components in PoE- the PSE (Power Sourcing Equipment) and 
the PD (Powered Device). The IEEE 802.3af/at specification defines PSE as a device that 
inserts power onto an Ethernet cable. The PSE may be located at the switch (Endspan 
configuration) or it may be a seperate device located between the switch and the PD 
(Midspan configuration). The PD is the natural termination of this link, receiving the 
power, and could be an IP phone, a WLAN access point, or any other IP device that 
requires power. 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/at specification 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 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 the PSEs exactly how 
much power they need. 
The PoE switch is a multi-port fast ethernet switch that can be built high-performance 
switch network. This is a store-and-forward device that offers low latency for high-speed 
network. It also allows the switch to auto-learn and store source addresses in a 4K-entry 
MAC address table. The switch is targeted at workgroup, department or backbone 
computing environments.

FCC Statement 
This equipment has been tested and found to comply with the limits for a class B device, pursuant 
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against 
harmful interference in a commercial installation. This equipment generates, uses and can radiate 
radio frequency energy and, if not installed and used in accordance with instructions, may cause 
harmful interference with radio communications. Operation of this equipment in a reidential area 
is likely to cause harmful interference, in which case, the user will be required to correct the 
interference at the user’s expense.
• RJ-45 Ports
Use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cable for RJ-45 connections: 
100Ω Category 3, 4 or 5 cable for 10 Mbps connections, 100Ω Category 5 cable for 100Mpbs 
connections, or 100Ω Category 5e/above cable for 1000Mbps connections. Also be sure that 
length of any twisted-pair connection does not exceed 100 meters (328feet). We suggest 
using Category 5e cable when connect a power to the device. 
• Improper Network Topologies 
It is important to make sure that the network topology is valid. Common topology faults 
include excessive cable length and too many repeaters (hubs) between the nodes. 
In addition to that, you should make sure your network topology contains no data path 
loops. Between any two ends nodes, there should be only one active cabling path at any 
time. Data path loops will cause broadcast storms which could severely impact your network 
performance.
• Diagnosing LED Indicators
To identify the problems, switches can be easily monitored through panel indicators, 
which describe common problems the user may encounter and where the user can find 
possible solutions. If the LED display detection isn’t correct, please unplug and plug back 
into the cable again. If the power indicator does not light when the power cord is plugged 
in, you may have a problem with the power outlet or power connections, power losses, or 
surges at power outlet. If the problem still cannot be resolved, please contact the local 
serive technician for assistance.

• RJ-45 Ports (Auto MDI/MDIX)
  8 Auto-sensing ports of 10Base-T, 100Base-TX or 1000Base-TX connections. 
  [In general, MDI means connecting to another Hub or Switch while MDIX means 
  connecting to a workstation or PC. Therefore, Auto MDI/MDIX means that you can 
  connect to another Switch or workstation without changing pin-to-pin or crossover  
  cabling.] All of these ports can supply to PDs.

Network Application
The PoE switch is designed as a segment switch that has a large address table and high 
performance to deal with interconnecting networking segments. 
PC, workstations, and servers can communicate with each other by directly connecting with 
the PoE switch. The switch automatically learns nodes addresses, which are subsequently 
used to filter and forward all the traffic based on destination address. 
The PoE Switch can provide power to PDs that follow the IEEE 802.3af/at standard in the 
network. It solves the problem of the position limitation. For a better performance, the 
network devices should be installed in an appropriate position. The following figure is an 
example of network application for Power over Ethernet Swtich.

Troubleshooting
This section is intended to help solve the most common issues with the PoE Switch
• Incorrect Connection
Every port on the switch can automatically detect either straight or crossover cables when 
you connect it to the Ethernet devices. However, depending on the device, others may 
demand a specific cable type. Choose appropriate cable to connect between the units. 
The RJ-45 connector should use correct UTP or STP cable, 10/100 Mbps port use 2-pairs of 
twisted cable. If the RJ-45 connector is not correctly pinned then the link will fail.
• Faulty or Loose Cables
Look for loose or faulty cable connections. If they are appeared to be okay, make sure the 
connections are snug. If the problem is not fixed, try a different cable and disconnect the 
cable and reconnect it.
• Non-Standard Cables 
Non-Standard and miswired cables may cause numerous network collisions and corrupt 
other network performance. A cable tester is the recommended tool to verify the connection 
in a cable signal.
