D3CM1604 DOCSIS 3.0 Cable Modem Administrator Manual

Basic Troubleshooting Procedures

The following covers basic troubleshooting procedures. Carefully review the sections to
make sure you follow the recommended procedures.

Always start your network using the following sequence

1. Unplug the cable modem and any other routers or switches.

2. Shut down connected computers.

3. Plug in the cable modem first and wait for the lights to cycle through the startup routine.

This prevents another device from taking the DHCP lease.

4. Plug in any other routers and switches.

5. Start up your computer.

Check basic Cable Modem functions

After you turn on power to the cable modem, check that the following LED sequences have
occurred

(and see “Front Panel” on page 13):

1. When power is first applied, verify that the

POWER

LED is ON.

2. After about a minute, verify the statuses of the following LEDs on the front panel of the

cable modem (see Figure 1-2 on page 13):



ONLINE

= ON (cable modem is operational)



DS

= ON (cable modem is connected to the Internet)



US

= ON (cable modem is connected to the Internet)

If this behavior does not occur, see Table 5-1. If the incorrect behavior persists, use the
Reset button to return the cable modem to its factory default configuration settings (see
“Using the Reset Button” on page 16).
