this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following
measures:

 Reorient or relocate the receiving antenna.
 Increase the separation between the equipment and receiver.
 Connect the equipment into an outlet on a circuit different from that to which

Introduction

Power-over-Ethernet (PoE) eliminates the need to run VAC power to other devices on

a wired LAN. Using Power-over-Ethernet system installers needs 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 significantly decreasing
installation costs in many cases.

There are two system components in PoE—the Power Sourcing Equipment (PSE)
initiates the connection to the second component, and the Powered Device (PD). 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 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 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 8 10/100TX + 2 10/100/1000T / 100/1000Mini-GBIC Combo with 8 PoE Managed
Switch is the multi-port switches that can be used to build high-performance switched
workgroup networks. Any one of the switch is a store-and-forward device that offers low
latency for high-speed networking. It also features a ―store-and-forward ―switching
scheme. This allows the switch to auto-learn and store source address in an 8K-entry
MAC address table. The switch is targeted at workgroup, department or backbone
computing environment.

Hardware Description

This section mainly describes the hardware of the PoE Managed Switch and gives a

physical and functional overview on the certain switch.

Physical Dimension

The physical dimensions of 8 10/100TX + 2 10/100/1000T / 100/1000Mini-GBIC Combo

with 8 PoE Managed Switch are 217mm(W) x 43mm(H) x 140mm(H).

Front Panel

The front panel of the 8 10/100TX + 2 10/100/1000T / 100/1000Mini-GBIC Combo with 8

PoE Managed Switch consists of 8 x 10/100Base-TX RJ-45 Ethernet ports (Auto

MDI/MDIX), 2 Gigabit combo ports involve 2 10/100/1000Mbps Ethernet RJ-45 port

(automatic MDI/MDIX) and 2 100/1000 Mini-GBIC ports. The LED Indicators are also

located on the front panel of the switch.

The Front panel of the 8 10/100TX + 2 10/100/1000T / 100/1000Mini-GBIC Combo with 8 PoE Managed

Switch

 RJ-45 Ports: There are 8 10/100 N-way auto-sensing for 10Base-T or 100Base-TX

connections and 2 10/100/1000Mbps auto-sensing for 1000Base-T connection
RJ-45 ports. The 8 10/100 ports also can supply power to PDs.
In general, MDI means connecting to another Hub or Switch while MDIX means
connecting to a workstation or PC. Therefore, Auto MDI/MDIX would allow
connecting to another switch or workstation without changing non-crossover or

12

crossover cabling.

 Mini-GBIC port: The appropriate replaceable Mini-GBIC port is available with a

variety of different transmitter and receiver types, allowing users to select the
appropriate transceiver for each link to provide the required optical reach over
the available optical fiber type.

will work with AC in the voltage range of AC 100-240V with Frequency of 50-60Hz.

The Rear Panel of 8 10/100TX + 2 10/100/1000T / 100/1000Mini-GBIC Combo with 8 PoE Managed Switch

14

Desktop Installation

Set the switch on a sufficiently large flat space with a power outlet nearby. The surface

where you put the switch should be clean, smooth, level and sturdy. Make sure there is

enough space around the switch to allow air circulation.

Attaching Rubber Pads

A. Make sure mounting surface on the bottom of the switch is grease and dust free.

B. Remove adhesive backing from your Rubber Pads.

C. Apply the Rubber Pads to each corner on the bottom of the switch. These footpads

can prevent the switch from shock/vibration.

Power On

Connect the DC jack to the power socket on the rear panel of the switch. Connect the

other side of power plug to the power outlet. The power adaptor works with voltage range

of AC in the 100 -240VAC/Frequency of 50~60Hz for 8 10/100TX + 2 10/100/1000T /

100/1000Mini-GBIC Combo with 8 PoE Managed Switch. Check the power indicator on

the front panel to see if power is properly supplied.

15

Network Application

This section provides a few samples of network topology in which the switch is used. In

general, the PoE Managed Switch is designed as a segment switch which has large

address table (8k MAC addresses) and high performance to deal with interconnecting

networking segments.

Using the uplink port (Giga Combo port), the switch can connect with another switch or

hub to interconnect other small-switched workgroups to form a larger switched network.

Besides, the PoE switch also injects power into the UTP cables for supplying the power

that PDs (Power Devices) need.

The Power over Ethernet Switch can provide power to PDs that follow the IEEE 802.3af

standard in the network. It can solve the problem of position limitation. The network

devices can be installed in more appropriate position for better performance. The

following figure is an example of network application for Power over Ethernet Switch.

Small Workgroup

The PoE managed switch can be used as a standalone switch to which personal

computers, server, printer server, are directly connected to form a small workgroup.

Small Workgroup application

16

Segment Bridge

For enterprise networks where large data broadcasts are constantly processed, this

switch is an ideal solution for department users to connect to the corporate backbone.

In the illustration below, two managed PoE switches with PCs, print server, local server,

wireless AP (IEEE 802.3af compliant), and IP camera (IEEE 802.3af compliant) attached

are both connect to the core switch. All the devices in this network can communicate with

each other through the core switch.

Segment Bridge application

17

Console Management

Login in the Console Interface

When the connection between switch and PC is ready, turn on the PC and run a terminal

emulation program or Hyper Terminal and configure its communication parameters to

match the following default characteristics of the console port:

Baud Rate: 9600 bps

Data Bits: 8

Parity: none

Stop Bit: 1

Flow control: None

The settings of communication parameters

After having finished the parameter settings, click ―OK―. When the blank screen shows

up, press Enter key to bring forth the login prompt. Key in the ‗root‘ (default value) for

both User name and Password (use Enter key to toggle), then hit Enter key and the

console management appears right after. Please see the figure below for login screen.

Console login screen

CLI Management

The system supports console management—CLI command. After you log in to the

system, you will see a command prompt. To enter CLI management interface, enter

―enable‖ command. The following table lists the CLI commands and description.
