1Introduction
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 need to run only a single Category 5 Ethernet cable that carries both power and data
to each device. This allows greater flexibility in the locating of network devices and, in many cases, significantly
decreases installation costs.
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 (End-span configuration). or it may be a separate device located between the switch and the
PD (Mid-span 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 is at the other end of the cable. It also continues
to monitor the channel. If the 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 to the PSEs exactly how much power they need.
The PoE switch is a multi-port fast Ethernet switch that can be used to build high-performance switched workgroup
networks. This switch is a store-and-forward device that offers low latency for high-speed networking. It also
features a ‘store-and-forward switching’ scheme that 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.

The switch can be mounted in an EIA standard size 19-inch rack; which can be placed in a wiring closet with other
equipment. To install, attach the mounting brackets to the switch’s side panels (one on each side) and secure them
with the screws provided.
Then, use the screws provided with the equipment rack to mount the switch in the rack.
Please be aware of following safety instructions when installing:
n Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room temperature. Therefore, consideration should
be given to installing the equipment in an environment compatible with the maximum ambient temperature
(Tma) specified by the manufacturer.
n Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required
for safe operation of the equipment is not compromised.
n Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
n Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit
and the effect that overloading of the circuits might have on over current protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
n Reliable Grounding - Reliable Grounding of rack-mounted equipment should be maintained. Particular
attention should be given to supply connections other than direct connections to the branch circuit (e.g. use of
power strips)."
3.3 Grounding the Switch
The section describes how to connect the switch to ground. You must complete this procedure before powering your
switch.
Required Tools and Equipment
l Ground screws: One M4 x 6mm (metric) pan-head screw
l Ground cable: The grounding cable should be sized according to local and national installation requirements.
Depending on the power supply and system, a 6 to 12 AWG copper conductor is required for U.S installation.
Commercially available 6 AWG wire is recommended. The length of the cable depends on the proximity of
the switch to proper grounding facilities.
l A screwdriver

The following steps let you connect the switch to a protective ground:
Step 1: Verify if the system power is off.
Step 2: Use the ground cable to place the #8 terminal lug ring on top of the ground-screw opening, as
seen in the figure below.
Step 3: Insert the ground screw into the ground-screw opening.
Step 4: Using a screwdriver, tighten the ground screw to secure the ground cable to the switch.
Step 5: Attach the terminal lug ring at the other end of the grounding cable to an appropriate grounding
stud or bolt on rack where the switch is installed.
Step 6: Verify if the connections at the ground connector on the switch and the rack are securely
attached.
3.4 Plugging in the AC Power Cord
Users may now connect the AC power cord into the rear of the switch and to an electrical outlet (preferably one that
is grounded and surge protected).
Power Failure
As a precaution, the switch should be unplugged in case of power failure. When power is resumed, plug the switch
back in.

4Troubleshooting
This section is intended to help solve the most common issues with the PoE Switch
Incorrect connections
Every port on this switch can automatically detect either straight or crossover cables when you link it with other
Ethernet devices but other devices may demand a specific cable type (depending on the device). Choose the
appropriate cable to connect between the units. The RJ-45 connector should use correct UTP or STP cable,
10/100Mbps port use 2-pairs twisted cable. If the RJ-45 connector is not correctly pinned then the link will fail.
Faulty or loose cables
Look for loose or obviously faulty connections. If they appear to be OK, make sure the connections are snug. If that
does not correct the problem, try a different cable.
Non-standard cables
Non-standard and miss wired cables may cause numerous network collisions and other network problems, and can
seriously impair network performance. A cable tester is the recommended tool for network installation.
RJ-45 ports: Use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cable for RJ-45 connections: 100Ω
Category 3, 4 or 5 cables for 10Mbps connections, 100ΩCategory 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 (328 feet). We suggest using Category 5e cable when connection to power a device.
Improper Network Topologies
It is important to make sure that you have a valid network topology. Common topology faults include excessive
cable length and too many repeaters (hubs) between end nodes. In addition, you should make sure that 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 that will severely impact your network performance.
Diagnosing LED Indicators
To assist in identifying problems, the switch 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 then plug in the cable again.
If the power indicator does not light when the power cord in 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 dealer for assistance.
5 Getting Started
This chapter introduces the management interface of the switch.

5.1 Management Options
The Switch can be managed through any port on the device by using the Web-based Management
Each switch must be assigned its own IP Address, which is used for communication with Web-Based Management.
The PC’s IP address should be in the same range as the switch. Each switch can allow only one user to access the
Web-Based Management at a time.
Please refer to the following installation instructions for the Web-based Management.
5.2 Using Web-based Management
After a successful physical installation, you can configure the switch, monitor the network status, and display
statistics using a web browser.
Connecting to the Switch
You will need the following equipment to begin the web configuration of your device:
n A PC with a RJ-45 Ethernet connection
n A standard Ethernet cable
Connect the Ethernet cable to any of the ports on the front panel of the switch and to the Ethernet port on the PC.
Login Web-based Management
In order to login and configure the switch via an Ethernet connection, the PC must have an IP address in the same
subnet as the switch. For example, if the switch has an IP address of 192.168.2.1, the PC should have an IP address
of 192.168.2.x (where x is a number between 2 ~ 254), and a subnet mask of 255.255.255.0. Open the web browser
and enter 192.168.2.1 (the factory-default IP address) in the address bar. Then press <Enter>.
When the following logon dialog box appears, enter the username and password then click OK. The default
username is admin and password is system.

6.2 Administrator
Administrator -> Authentication Configuration
Here you can enter a new Username/Password and confirm it.
The factory default
IP address: 192.168.2.1
Username: admin
Password: system
Administrator -> System IP Configuration
There are two ways for the switch to obtain an IPaddress: Static and DHCP (Dynamic Host Configuration Protocol).
When using static mode, the IP address, Subnet Mask and Gateway can be manually configured. When using
DHCP mode, the Switch will first look for a DHCP server to provide it with an IP address (including network mask
and default gateway) before using the default or previously entered settings. By default the IP setting is static mode
