1. Introduction
1.1.Product Overview
The 5/8 Port Fast Ethernet Switch can significantly increase your network traffic speed. A switch serves
the same function as a hub in a network - tying your network equipment together. However, unlike a
simple hub which divides the network’s bandwidth among all the attached devices by indiscriminately
sending data from all ports to all ports to be accepted or rejected and causing collisions or being slowed
down when more than one device is sending information, a switch makes maximum use of available
bandwidth by only distributing data where it is needed and through multiple simultaneous and
independent paths. Installing this cost-effective 5/8 Port Fast Ethernet Switch can potentially increase
your network speed by five or eight times! It's the perfect way to integrate 10Mbps Ethernet and
100Mbps Fast Ethernet devices, too. All ports are auto speed negotiating, and have automatic
MDI/MDI-X crossover detection, so installation is worry free. 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 in the network. The new,
ultra-compact case design is sure to fit into your work group environment. Let the 5/8 port Fast Ethernet
switch kick your 10/100 network into high gear.

2. Installation
2.1.Before Installation
Take note of the following conditions before using your switch:
¾Install the 5/8 port Fast Ethernet switch in a fairly cool and dry place. See Working Environment for
the acceptable operating temperature and humidity ranges
¾Install the switch in a site free from strong electromagnetic sources, vibration, dust, and direct
sunlight.
¾Leave at least 10cm of space to both the left and right of the switch for ventilation.
¾Visually inspect the DC power jack and make sure the power adapter cord is securely connected.
¾Do not place items on top of switch
2.2.Connecting the 5/8 Port Fast Ethernet Switch to Your
Network
Description Function
PWR Connect to power adapter provided with unit. Don’t use other
power adapters as your switch could be damaged.
LAN1-5/8
These ports support network speeds of 10Mbps or 100Mbps, and
can operate in half and full-duplex transfer modes. These ports also
support automatic MDI/MDIX detection, which gives the Switch
true ‘plug and play’ capabilities. Just connect any network cable
from a device to the switch, and the switch will automatically
detect the settings of the device and adjust itself accordingly.
2.3.LED Indicators
The LED Indicators will allow you to monitor, diagnose and troubleshoot any potential problem with the
switch, connection or attached devices.

3. Troubleshooting
1. The Power LED is not lit
¾Check if the AC power cord is well connected. Try to unplug and plug back in the power cord to
the LAN Switch or try another power outlet.
2. The Link LED is not lit
¾Make sure the network configuration of connecting device is correct, and network card and drivers
are installed correctly.
¾Check the cable connections.
¾Make sure the cable distance between the switch and other IEEE802.3 compatible network device
does not exceed 100 meters.
3. Performance is bad
¾Check the status of Ethernet switching. If Ethernet switching is set to full-duplex on one device but
a partner is set to half-duplex, then performance will be poor.
¾Make sure the cable between the switch and other IEEE802.3 compatible network device is
Category 5 UTP or better.
4. Some devices can’t talk to other devices on the network
¾Check status of the Link LEDs to make sure devices are linked.
¾Make sure that the devices' network configurations are correct.
¾Reset the switch if needed.
