Turning on the Modem

The power cable connects the rear of the modem to a standard 115V outlet. After making other connections, plug the power cable into the modem, and then plug it into an outlet. Turn the rear panel power switch to the On (up) position.

When powered on, the modem automatically performs a self-test of internal circuits. The "Automatic Self-Test" section, next, describes this test and the front panel displays that can follow it.
