AVN-S24-2P24W400G

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 8K-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.
