Note: Your model number is 7931. It is important that you have your serial number
written down before you install the 24-Port 10/100/1000Mbps Switch. You can find your
serial number on the bottom label of the 24-Port 10/100/1000Mbps 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.
Step 1. Connect the power supply
100-240VAC
Step 2. Connect your 24-Port 10/100/1000Mbps Switch to your Ethernet-
ready device

Congratulations!
The installation of your U.S.Robotics 24-Port 10/100/1000Mbps Switch is
complete. As connections are established with the 24-Port 10/100/1000Mbps Switch, the
corresponding LED lights will turn on. Repeat this step as needed for up to twenty-three
additional devices.

Troubleshooting
My 24-Port 10/100/1000Mbps 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 1000 Mbps.
You may be using a 10/100 Mbps device. A blinking orange light indicates you are receiving and
transmitting data at 10/100 Mbps. A blinking green light indicates you are receiving and transmit-
ting data at 1000 Mbps. To achieve 1000 Mbps speeds, replace any 10/100 Mbps devices you are
using with 1000 Mbps devices.
Possible Solution:
Verify you are using a known and reliable RJ-45 Category 5 Ethernet cable. An old or unreliable RJ-
45 Category 5 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 24-Port 10/100/1000Mbps Switch and your
workstation or computer should not exceed 328 feet. Some power sources with strong
electromagnetic fields may be causing interference.
