AIVO NETWORKS AVN-S05-1P04W65G User Manual

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.
User Manual
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
Professional 10/100/1000 Ethernet PoE Switch
Equipment (PSE) tests whether a networked device is PoE-capable, power is never
AVN-S05-1P04W65G 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 8K-entry
MAC address table. The switch is targeted at workgroup, department or backbone
computing environments.
