Chapter 1 Introduction
Congratulations on your purchase of this 10/100Mbps switch. Instructions for installing
and configuring this product can be found in this manual. Before you install and use this
product, please read this manual carefully for full exploiting the functions of this product.
The 10/100Mbps switch is the perfect way of integrating 10Mbps Ethernet and 100Mbps
Fast Ethernet devices. All eight ports are auto speed negotiating, and have automatic
MDI/MDI-X crossover detection, so you don't have to worry about the cable type. Each
port independently negotiates for best speed and half- or full-duplex mode, for up to
200Mbps of bandwidth per port. Fast store-and-forward switching prevents damaged
packets from being passed on into the network.
1.1 Features
Eight 10/100BASE-T Ethernet Ports
Support Auto-Negotiation for 10/100Mbps
Support Auto-MDI/MDIX for each port
Support Full/Half duplex transfer mode for 10/100Mbps
Complies with IEEE 802.3, IEEE 802.3u
Perform forwarding and filtering at non-blocking, full-wire speed
Built-in high-efficiency SRAM for packet buffer and 1K-entry look-up table
Supports IEEE 802.3x for full-duplex flow control and back pressure for
half-duplex flow control
Support packet lengths up to 1536 bytes
Support Store-and-Forward switching method
Support Broadcast Storm Filtering Control

Chapter 2 Installation
2.1 Front Panel LEDs
Power LED
This red indicator illuminates when the Switch is receiving power.
Link/Act (1- 8)
This blue indicator illuminates steadily when a port is connected to a station successfully,
If this blue indicator is blinking, it indicates that a port is transmitting or receiving data on
the network.
2.2 Back Panel and Side Panel Features
This network ports are located on the back panel of the switch. The Power port is located
on the side of the switch
1- 8
These ports are connection points for PCs and other network devices, such as
additional switches
Power
The power port is where you will connect the included power adapter

2.3 Connecting Network Devices
To connect network devices to the Switch, follow these instructions.
1. Make sure all the devices you will connect to the Switch are powered off
2. Connect a Category 5 Ethernet network cable to one of the numbered ports on
the Switch
3. Connect the other end to a PC or other network devices
4. Repeat steps 2 and 3 to connect additional devices
5. Connect the supplied power adapter to the power port on the Switch’s back panel
Note: Make sure you use the power adapter included with the Switch. Using a
different power adapter may result in damage to the Switch.
6. Plug the other end of the adapter into an electrical outlet
7. Power on the devices connected to the Switch. Each active port’s corresponding
LED will light up on the Switch
Note: If wrongly installed or improperly used in the living area, the device can cause interference in radios
and other electronic devices. Appropriate use is when the device, as far as feasible, is operated with
shielded connection cables (with network products in addition to category 5 shielded cables and higher).
The device has been tested and falls within the limits of class B computing equipment according to the
requirements of EN 55022.
Warning: This device conforms with test category B - it can cause radio interference in the living area; in
this case the operator may demand that appropriate measures are implemented and arise for this reason.
Declaration of conformity: The device fulfills the EMV requirements according to EN 55022 for ITE and EN
55024. Devices with external or integrated power supply furthermore fulfill the requirements of EN
61000-3-2 and EN 61000-3-3. In this way, the fundamental protection requirements of the
EMV-2004/108/EC guideline are fulfilled. The CE conformity has been proven. The pertinent declarations
are deposited with the manufacturer.
