These explainer slides outline the basic features of a Power over Ethernet (PoE) device network and how they work together to save time and money while offering the enhanced benefits of connectivity.

2. What is
Power over Ethernet
PoE is a term for systems which pass
both electric power and data on twisted
pair Ethernet cabling.
PoE increases connectivity.
Poe increases efficiency.
PoE increases productivity.

4. Control Computer
This is a PC computer dedicated to administering
the power over Ethernet (PoE) network.
The control computer enables users to configure a
PoE system’s functionality and automate processes.
The control computer empowers users with actable
information received in real time from sensors and
monitors throughout the system.
The specified configuration — or what you see on the screen and what it does —
will change depending on which devices are integrated across the network.

5. Ethernet Cable
Ethernet cable makes power over Ethernet (PoE) possible.
Before it was able to shuffle around power, Ethernet cable
was already a popular type of network cable used to connect
devices in wired, local area networks.
Different types of Ethernet cables have different capabilities.
A certain type of Ethernet cable will be more suited to a
situation than another. In a PoE system, it is common to see
Cat5 and Cat6 Ethernet cables.

6. Z-MAX 6A Shielded Connector
This is a top of the line Ethernet connector that we
add to all our Ethernet cables in our PoE system.
The Z-MAX is a PoE specialty connector. It is the
industry’s fastest termination line and prevents alien
crosstalk to protect your equipment and your signal.

7. Regulated Power Supply
Encompass AV takes extra precautions by
including a regulated power supply to condition
AC power and protect against surges.
It also provides a minor backup battery.
It is common to integrate the regulated power
supply into a rack for easy access.

8. PoE Switch
1. Transferring electrical power - the switch takes in AC power, converts it to DC
power, and distributes it to ports.
2. Transferring data - The switch passes information back and forth between the
network server and the PoE devices.
The negotiation of power and data take place through the switch’s ports. Switches have
multiple ports, but they are limited by how much power they may pass.
This is the hub of a power over Ethernet system, and it
manages the following processes:

9. PoE Powered Devices
PoE powered devices are electronics and
appliances enabled to receive power and data
over one cable plugged into one port.
There is a lot of new and exciting development
in this area.
Encompass AV is currently focused on
commercial solutions like overhead lighting,
wireless access points, enhanced security
systems, VoIP communication, and powering
digital signage.
Some of PoE devices:
● Overhead lighting
● VoIP phones
● Intercom systems
● Access control
● Monitoring systems
● Point of sale
● Cameras

10. Sensors
Sensors communicate information
about an area so PoE devices and
fixtures can be reactive to their
environment.
Examples of Sensors:
● Motion
● Light
● Temperature
● Humidity
PoE carries low-voltage power, which
is safer than high-voltage, and it does
not require hard conduit. This means
cables can be neatly secured with
repositionable straps and rings behind
the ceiling and walls.
