4. Power over Ethernet Overview
What is PoE?
Based on the global standard IEEE 802.3af, PoE is a technology for wired Ethernet,
the most widely installed local area network technology adopted today. PoE allows
the electrical power necessary for the operation of each end-device to be carried
by data cables rather than by separate power cords. New network applications,
such as IP Cameras, VoIP Phones, and Wireless Networking, can help enterprises
improve productivity. It minimizes wires that must be used to install the network
for offering lower cost, and less power failures.
IEEE 802.3af also called Data Terminal equipment (DTE) power via Media
dependent interface (MDI) is an international standard to dene the transmission
for power over Ethernet. The 802.3af is delivering 48V power over RJ-45 wiring.
Besides 802.3af also dene two types of source equipment: Mid-Span and End-
Span.
Mid-Span
Mid-Span device is placed between legacy switch and the powered device. Mid-
Span is tap the unused wire pairs 4/5 and 7/8 to carry power, the other four is
for data transmit.
End-Span
End-Span device is direct connecting with power device. End-Span could also tap
the wire 1/2 and 3/6.
PoE System Architecture
The specication of PoE typically requires two devices: the Powered Source
Equipment (PSE) and the Powered Device (PD). The PSE is either an End-Span
or a Mid-Span, while the PD is a PoE-enabled terminal, such as IP Phones, Wireless
LAN, etc. Power can be delivered over data pairs or spare pairs of standard CAT-5
cabling.
How Power is Transferred Through the Cable
A standard CAT5 Ethernet cable has four twisted pairs, but only two of these are
used for 10BASE-T and 100BASE-T. The specication allows two options for using
these cables for power, shown in Figure 2 and Figure 3:
The spare pairs are used. Figure 2 shows the pair on pins 4 and 5 connected
together and forming the positive supply, and the pair on pins 7 and 8 connected
and forming the negative supply. (In fact, a late change to the spec allows either
polarity to be used).

17
Figure 1 - Power Supplied over the Spare Pins
The data pairs are used. Since Ethernet pairs are transformer coupled at each
end, it is possible to apply DC power to the center tap of the isolation transformer
without upsetting the data transfer. In this mode of operation the pair on pins 3
and 6 and the pair on pins 1 and 2 can be of either polarity.
Figure 2 - Power Supplied over the Data Pins

18
When to install PoE?
Consider the following scenarios:
You’re planning to install the latest VoIP Phone system to minimize cablingl
building costs when your company moves into new ofces next month.
The company staff has been clamoring for a wireless access point in the picnicl
area behind the building so they can work on their laptops through lunch, but
the cost of electrical power to the outside is not affordable.
Management asks for IP Surveillance Cameras and business access systemsl
throughout the facility, but they would rather avoid another electrician’s
payment.

5.Troubleshooting
This chapter contains information to help you solve issues. If the Switch is not
functioning properly, make sure the Ethernet Switch was set up according to
instructions in this manual.
The Link LED is not lit
Solution:
Check the cable connection and remove duplex mode of the Switch.
Performance is bad
Solution:
Check the full duplex status of the Switch. If the Ethernet Switch is set to full
duplex and the partner is set to half duplex, then the performance will be poor.
100Base-TX port link LED is lit, but the trafc is irregular
Solution:
Check that the attached device is not set to dedicate full duplex. Some devices use
a physical or software switch to change duplex modes. Auto-negotiation may not
recognize this type of full-duplex setting.
Why the Switch doesn’t connect to the network
Solution:
Check the LNK/ACT LED on the Switch Try another port on the Switch Make sure
the cable is installed properly, Make sure the cable is the right type. Turn off the
power. After a while, turn on power again.
Why I connect my PoE device to GSD-804P and it cannot power on?
Solution:
1. Please check the cable type of the connection from GSD-804P(port 1 to port
4) to the other end. The cable should be an 8-wire UTP, Category 5 or above,
EIA568 cable within 100 meters. A cable with only 4-wire, short loop or over
100 meters, all will affect the power supply.
2. Please check and assure the device that fully complied with IEEE 802.3af stan-
dard.
What is the power output of each IEEE 802.af PoE port?
Solution:
Each PoE port supports 48V DC, 350mA, max 15.4 Watts power output. Detect
and inject by the standard of IEEE 802.3af.
