24-Port 10/100M Ethernet PoE Switch (af Version 15.4W)
Table of Contents

1. Introduction
The 24-Ports10/100M Ethernet PoE Switch combines a high efficiency 24-ports 10/100Mbps Ethernet switch and a
standard 802.3af 24-ports Power over Ethernet (PoE) capability. The 24-Ports 10/100M Ethernet PoE Switch
incorporates an internal 48VDC power supply. Each of the PoE Ethernet ports can support 15.4 Watts of power as
well as 10/100M data transmission over the Inter- connecting Ethernet interface such as Cat 5/ 5e /6 cables.
The 24-Ports 10/100M Ethernet PoE Switch is a Power Source Equipment (PSE) and fully compatible with Powered
Devices (PD) that comply with the IEEE 802.3af PoE standard. The 24-Ports 10/100M Ethernet PoE Switch PoE
Switch enables users to attach IEEE802.3af compliant devices such as wireless Access Points (APS), VOIP phone,
IP camera, printer and Network Attached Storage (NAS) directly to the 24-ports 10/100 Ethernet PoE Switch without
requiring additional power on the network. The unit is designed for home and small business users in mind and is ideal
for installations where AC power is not available or no cost-effective.
No configuration is required and installation is quick and easy. Support for Auto –MDI / MDI-X on all of the ports
eliminate the need for crossover connection to another switch or HUB. Auto - Negotiation on each port senses the
link speed of a network device ( either 10 or 100) and intelligently adjusts for compatibility and optimal performance.
* 1-Year Limited Warranty for switch and 1-Year Limited Warranty for the power adaptor are available
* This device is designed for indoor use. Do not use outdoors.
* included are the installation manual.

•Power Over Ethernet (PoE):
Power over Ethernet (PoE) integrates 48V power and data onto one single cable, eliminating the need to have
AC power available at all equipment locations. Power and Data are integrated onto the same cable, supporting
category 5/5e up to 100 Meters. PoE provides power to PoE compatible devices, such as VOIP telephones,
wireless LAN access points, and IP security cameras.
PoE device are ready in the market, saving up to 50% of overall installation cost by eliminating the need to install
separate electrical wiring and power outlets.
•Features:
24 x 10/100Mbps Auto-negotiation Fast Ethernet RJ-45 ports with 24-Ports PoE function ( port 1 ~ port 24).
Compliant with IEEE 802.3af(24-Port 10/100M Ethernet PoE Switch).
Supports PoE power up to 340W for all PoE ports.
Supports PoE IEEE802.3af compliant Powered Device (PD)
Each port supports auto MDI/MDIX, so there is no need to use cross-over cables.
Full/half duplex transfer mode for each port.
Wire speed reception and transmission.
Up to 4K unicast address entities per device. Self-learning, and table aging.
64KBytes packet buffer.

8. Troubleshooting
24-Port 10/100M Ethernet PoE Switch/AT Rev 1.0 04/10/2012 Page 8 / 8
1> After connecting the Switch to a power outlet, the LEDs do not turn on.
Check the connection of the power cord to the 24-Ports 10/100M Ethernet PoE Switch
and the power outlet.
Check that the power outlet is receiving power.
2> When I connect a computer to the Switch's port, the Link/ACT LED turns on, but
the 100Mbps LED remains off.
When the 100Mbps LED is off, the computer's connection speed is 10Mbps.
3> After I connect my PCs to the Switch, I am unable to share files.
1. Check the LEDs on the Switch. Make sure the Link/ACT LED is on.
2. Check the network cable. The minimum length of the cable is 1.5 meters and the
maximum length of the cable is 100 meters.
3. Disable any software firewall program.
4. Verify that you have file sharing enabled. Please contact your Operating System
support for more information.
4> After I connect my PCs to the Switch, I can only get onto the Internet from one
computer.
The Switch is not designed to share Internet between multiple computers. You need to
get an Internet route.
5> Where is the uplink port located on the Switch?
Since all the ports on the Switch are Auto-MDIX, any of the ports can be used as an
uplink port. If you still encounter problems or have any questions regarding the PoE
switch please contact local Technical Support Department.
