Before You Begin

Note: It is important that you have your serial number written down before you

install the 8-Port 10/100 Ethernet Switch. You can find your serial number on the
bottom label of the 8-Port 10/100 Ethernet Switch and on the side of the package. If
you ever need to call our Technical Support department, you will need this number
to receive assistance.

Connect your 8-Port 10/100 Ethernet Switch to
your Ethernet-ready device

Congratulations! The installation of your U.S. Robotics 8-Port 10/100 Ethernet Switch is

complete. As connections are established with the 8-Port 10/100 Ethernet Switch, the
corresponding LED lights will turn on. Repeat this step as needed for up to seven
additional devices.

This is one of many possible configurations.

Note: For networking information, refer to your operating system’s

documentation.

Troubleshooting

My 8-Port 10/100 Ethernet Switch is properly connected to my Ethernet-ready
device, but I still can’t establish a connection.

Possible Solution:

Verify you are using a known and reliable RJ-45 Category 5 Ethernet cable. An old or
unreliable RJ-45 Category Ethernet cable could disrupt your connection. It may be
necessary to replace your RJ-45 Category 5 Ethernet cable.

Possible Solution:

Check the LED status lights on your 8-Port 10/100 Ethernet Switch. A flashing yellow light
indicates you are receiving and transmitting data at 10 Mbps. A flashing green light
indicates you are receiving and transmitting data at 100 Mbps. If you don’t see any LEDs
lighted or blinking, it may be necessary to replace your RJ-45 Category 5 Ethernet cable.

Possible Solution:

The length of your Ethernet cable between your 8-Port 10/100 Ethernet Switch and your
workstation or computer should not exceed 328 feet. Some power sources with strong
electromagnetic fields may be causing interference.

Possible Solution:

It may be necessary to reconfigure the network settings of your operating system. Refer
to your operating system’s documentation regarding network configuration specifics.

My 8-Port 10/100 Ethernet Switch is properly connected to my Ethernet-ready
device, but my connection speed is slow.

Possible Solution:

Verify that your network adapter and/or additional Ethernet-ready device supports
100 Mbps. You may be using a 10 Mbps device. To achieve 100 Mbps speeds, replace any 10
Mbps devices you are using with 100 Mbps devices.

Possible Solution:

Check the LED status lights on your 8-Port 10/100 Ethernet Switch. A flashing yellow light
indicates you are receiving and transmitting data at 10 Mbps. A flashing green light
indicates you are receiving and transmitting data at 100 Mbps. If you only see blinking
LEDs, it may be necessary to replace your RJ-45 Category 5 Ethernet cable.

Possible Solution:

Verify you are using a known and reliable RJ-45 Category 5 Ethernet cable. An old or
unreliable RJ-45 Category Ethernet cable could diminish your link quality. It may be
necessary to replace your RJ-45 Category 5 Ethernet cable.

Possible Solution:

The length of your Ethernet cable between your 8-Port 10/100 Ethernet Switch and your
workstation or computer should not exceed 328 feet. Some power sources with strong
electromagnetic fields may be causing interference.

What kind of cables should I use?

Possible Solution:

The 8-Port 10/100 Ethernet Switch may be used with an RJ-45 Category 5 Ethernet cable.

Where is the uplink port?

Possible Solution:

Each port may be used as an uplink port since each supports auto-crossover. This means
that each port on the 8-Port 10/100 Ethernet Switch automatically allows for connecting
additional hubs, switches, or routers using an RJ-45 Category 5 Ethernet cable.
