Basic Functioning
After you turn on power to the modem, the following sequence of events should occur:
1. When power is first applied, verify that the Power LED initially displays red to indicate that
the self-test procedure is running (see “The Front Panel” on page 2 for an illustration and
explanation of the LEDs).
2. After approximately 10 seconds, verify that:
a. The Power LED changes color from red to green.
b. The LAN port LED is lit to indicate that the modem is connected to your PC or router.
