Introduction

The device is a powerful, high-performance Fast Ethernet Switch, with all
8 ports capable of 10 or 100Mbps auto-negotiation operation (NWay),
which means this switch could automatically negotiate with the connected
partners on the network speed and duplex mode. It is ideal for
micro-segmenting large networks into smaller, connected subnets for
improved performance, enabling the bandwidth demanding multimedia
and imaging applications. Moreover, the 10/100Mbps auto-sensing ability
provides an easy way to migrate 10Mbps to 100Mbps network with no
pain.
This switch supports PoE, which supplies power for connected devices
via CAT 5 and above twisted cables. By integrating the data transmitting
cable and power cord, it eliminates the effort constructing your network.
You could easily connect a Wireless AP or a VoIP phone to this switch
without looking outlets for them. Over current protection and circuit
shorting protection are also supported to ensure the safety.
The switch is plug-n-play without any software to configure and also fully
compliant with all kinds of network protocols. Moreover, the rich
diagnostic LEDs on the front-panel provide the operating status of
individual port and whole system.

RJ-45 Ports

All the RJ-45 ports in the device are auto-negotiating and auto-crossover.
An auto-negotiating port can detect and adjust to the optimum Ethernet
speed (10/100 Mbps) and duplex mode (full duplex or half duplex) of the
connected device.
An auto-crossover (auto-MDI/MDI-X) port automatically works with a
straight-through or crossover Ethernet cable.

802.3az ON/OFF button

Press in the 802.3az ON/OFF button on the device to turn on the EEE
(Energy efficient Ethernet) feature. Disable it if the remote side doesn’t

support EEE or you don’t want the network performance to be impacted

due to the latency from the additional time required for the sleep and
wake transition.

Rear Panel

The rear panel consists of one power receptacle and a push button to
turn on and off.

Power Receptacle

To be compatible with the electric service standards around the world, the
switch is designed to afford the power supply in the range from 100 ~
240VAC, 50/60Hz. Please make sure that your outlet standard to be
within this range.
To power on the switch, plug the female end of the power cord firmly into
the receptacle of the switch and the other end into an electric service
outlet. After the power cord installation, please check if the power LED is
illuminated for a normal power status.

Installation

This switch can be placed on your desktop directly, or mounted in a rack,
or mount on wall. The installation is a snap. Users can use all the
features of the switch with simply attaching the cables and turning the
power on.
Before installing the switch, we strongly recommend:

1. The switch is placed with appropriate ventilation environment. a
minimum 25mm space around the unit is recommended.

2. The switch and the relevant components are away from sources of
electrical noise such as radios, transmitters and broadband
amplifiers

3. The switch is away from environments beyond recommend
moisture

Desktop Installation

1. Install the switch on a level surface that can support the weight of
the unit and the relevant components.

2. Plug the switch with the female end of the provided power cord
and plug the male end to the power outlet.

Wall mount Installation

1. Screw the two provided screws into the wall 150 mm apart

8

horizontally. Leave a small gap between the head of the screw and
the wall. The gap should be big enough for the screw heads to
slide into the screw slots and the connection cables to run down
the back of the switch.

2. Align the holes on the back of the switch with the screws on the
wall. Hang the switch on the screws.

Warning!

Do not wall mount the product vertically or it will be dangerous. Please
attach the product on the wall horizontally! See the image below for
reference:

Rack-mount Installation

The switch can be mounted on an EIA standard size, 19-inch rack or in a
wiring closet with other equipment. Follow the steps below to mount your
switch on a standard EIA rack using a rack-mounting kit.

Rack-mounted installation requirements

1. Two mounting brackets

2. Eight M3 flat head screws and #2 philips screwdriver.

3. Four M5 flat head screws and #2 philips screwdriver.

Procedures to Rack-Mounting the Switch in the rack:

1. Disconnect all the cables from the switch before continuing.

2. Place the unit the right way up on a hard, flat surface with the front
facing you.

3. Locate a mounting bracket over the mounting holes on one side of
the unit.

4. Insert the screws and fully tighten with a suitable screwdriver.

5. Repeat the two previous steps for the other side of the unit.

6. Insert the unit into the rack and secure with suitable screws.

7. Reconnect all the cables.

Network Cables

In making a switch interconnection, you could use any port to connect
another switch with straight or crossover cable. As all the ports support
auto MDI / MDI-X function, using a straight cable to make a
switch-to-switch connection is allowed.

1. Crossover or straight-through cable: All the ports on the switch
support Auto-MDI/MDI-X functionality. Both straight-through or
crossover cables can be used to connect the switch with PCs as
well as other devices like switches, hubs or router.

2. Category 3, 4, 5, 5e or 6 UTP/STP cable: To make a valid
connection and obtain the optimal performance, appropriate
cables corresponding to different transmitting/receiving speed is
required. To choose a suitable cable, please refer to the following
table.
