Warning
This equipment has been tested and found to comply with the limits for Class B digital devices, pursuant
to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a residential installation. This equipment generates, uses,
and can radiate radio frequency energy and if not installed and used in accordance with the instruction
manual may cause harmful interference to radio communications. However, there is not guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the equipment on and off, 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 the receiver is
connected.
Consult the dealer or an experienced radio technician for help.
Notice: The changes or modifications not expressly approved by the party responsible for compliance
could void the user authority to operate the equipment.

1. Introduction
This 8-port Fast Ethernet switch series provides seven 10/100 TP ports and one 100BaseFX fiber
port, each capable of transmitting or receiving information simultaneously at full wire speed to
control and allocate the network bandwidth.
The key features of this switch unit are:
.Optimized Bandwidth: Combining eight 10/100Mbps-based Fast Ethernet switched ports, the
switch delivers a high network bandwidth for your Fast Ethernet network.
.Easy Migration: With 10BaseT support on each 10/100 port, the switch provides a non-
disruptive and smooth migration path from Ethernet to a Fast Ethernet network.
.Fiber Uplink Support: With 100BaseFX port, the switch provides connectivity to a Fast
Ethernet network via fiber cable.
.Easy Installation: With the functions of auto-speed-sensing and auto-negotiation on each port,
the switch supports plug-and-play installation which eliminates configuration problems.

1.1 Features
Designed for resolving congestion problems caused by bandwidth-hungry devices and
bandwidth-intensive applications as well as a high number of users, the switches not only adhere
to the IEEE 802.3 10BaseT, 802.3u 100BaseTX and 100BaseFX standards, but also feature:
.Seven 10/100BaseTX auto-negotiation switched ports and one 100BaseFX port for flexible
connections to desktop PCs, servers and Fast Ethernet devices.
. 10/100BaseTX switched ports that support:
- auto-negotiation with auto-negotiation devices
- full-duplex or half-duplex operation
- automatic MDI/MDI-X configuration
. For the 100BaseFX fiber port, the switch series support a variety of fiber connectors for
different application needs. The fiber connectors include ST or SC for multimode fiber cables
and SC for single mode fiber cables.
. Supports duplex mode selector for the 100BaseFX fiber port.
. Self-learning for active MAC addresses and address aging
. Store and forward switching to ensure only good packets are forwarded
. Forwarding and filtering at full wire speed
. Supports IEEE 802.3x flow control for full-duplex operation
. Supports back-pressure flow control for half-duplex operation
. Comprehensive LED indicators provide quick, easy to read port and switch information

2. Installing the Switch
2.1 Unpacking
Check to see that you have everything before you start the installation.
. Installation guide
. The switch unit
. One AC power adapter for the unit
2.2 Checking AC Power
Before you begin the installation, check the AC voltage of your area. The AC power adapter
used to supply the DC power for the unit should have the AC voltage matching the commercial
power voltage in your area. The specifications of the AC power adapter are:
. AC input power: AC power voltage of your area
. DC output power: +7.5VDC 1A min.
. DC plug type:
The DC power socket for the AC power adapter is located on the rear of the switch as shown
below:

2.3 Installing the Switch
1. Install the switch with the AC power adapter provided.
2. Connect the power adapter cable to the switch before connecting the adapter to the AC outlet.

3. Making Network Connections
3.1 Switched Ports
The following figure shows the location of the switched ports:
3.2 Making UTP Connections
10/100 TP Port Configuration
All 10/100 TP ports support configuration as follows:
Auto-negotiation capable
Highest capability: 100M Full duplex
Speed: auto-sensing for 100Mbps or 10Mbps
Duplex: Full duplex, half-duplex
Auto MCI-X function
The following table lists the configuration used for the 10/100 port when it connects to different
devices:
Connected Device Configuration Used
10BaseT hub port 10Mbps, half-duplex
100BaseTX hub port 100Mbps, half-duplex
Auto-negotiation port Determined by auto-negotiation process
Non-auto*1 half-duplex port auto-speed-sensing *2, half-duplex
Non-auto full-duplex port Not supported
*1 Non-auto: non-auto-negotiation
*2 speed is determined by auto-sensing function
Cables
Depending on the connection speed, use the proper UTP cables:
Speed Cables used Distance
100M Cat. 5, 5e, or higher grade 100 meters
10M Cat. 3, 4, 5, 5e or higher grade 100 meters
Auto-MDI-X Function
An Auto-MDI-X function will automatically detect if a crossover is required and make the swap
of Tx pair and Rx pair internally. With this function, straight-through cable can be used for any
connection. MDI to MDI-X connection rule is not necessary anymore. You can use just straight-
through type cable for all your connections.
