Front Panel LEDs
The Cable Modem’s LEDs are located on the front panel.
Figure 2-2: Front Panel
Power Green. The Power LED lights up when the Cable Modem is powered on. It stays solid after the
self-test. If the LED lights up red, the self-test has failed.
Internet, Online Green. The Online LED flashes when the Cable Modem is establishing a connection to your
cable ISP. It is solidly lit when the Cable Modem is synchronized with your cable ISP.
Internet, DS Green. The DS (Downstream) LED lights up and flashes when the Cable Modem is trying to
lock on a downstream signal. The LED stays solid when it has locked on the signal.
NOTE: If the US and DS LEDs are flashing, the
modem is still operating, but your Internet service
has been disabled by your Internet Service
Provider.
Internet, US Green. The US (Upstream) LED lights up and flashes when the Cable Modem is trying to lock
on an upstream signal. The LED stays solid when it has locked on the signal.
Ethernet Green. The Ethernet LED lights up when the Cable Modem is connected to your computer or
network through the Ethernet port. It flashes when there is activity on the Ethernet port. The
LED will light up orange when there is a data collision.
USB Green. The USB LED lights up when the Cable Modem is connected to your computer or
network through the USB port. It flashes when there is activity on the USB port. The LED will
light up orange when the USB is connected and before the driver is installed.

Chapter 3: Connecting the Cable Modem
Overview
You can connect the Cable Modem to your PC using either the Ethernet port or the USB port. If you use the USB
port, you will also have to install a USB driver on your PC. If you are using the Cable Modem’s Ethernet port,
proceed to the “Connection Using the Ethernet Port” section. If you are using the Cable Modem’s USB port,
proceed to the “Connection Using the USB Port” section.
Connection Using the Ethernet Port
1. Power off your PC. If you have an existing cable modem that you are replacing, disconnect it at this time.
2. Connect the coaxial cable from your Internet Service Provider (ISP) or cable company to the Cable port on
the back panel of the Cable Modem. (The other end of the coaxial cable should be connected according to
the ISP or cable company’s instructions.)
3. Connect the included Ethernet network cable to the Ethernet port on the back panel of the Cable Modem.
4. Connect the other end of the Ethernet network cable to the RJ-45 port of your PC’s Ethernet network adapter
or a network device, such as a router, switch, or hub.
NOTE: Make sure that you have TCP/IP installed on
your computer. For more information, refer to
“Appendix B: Windows Help.”
Figure 3-1: Connect the Coaxial Cable
5. Connect the included power adapter to the Power port on the back panel of the Cable Modem. Connect the
other end to a standard electrical outlet.
6. The Power LED on the front panel of the Cable Modem should light up and remain lit.
7. Power on your PC.
8. Contact your cable ISP to activate your account. Your cable ISP will need the MAC address for the Cable
Modem in order to set up your account. The 12-digit MAC address is printed on a bar code label on the bottom
of the Cable Modem. Once you have given them this number, your cable ISP should be able to activate your
account.
Congratulations! The installation of the Cable Modem is complete.
