Modem Power-Up

Once your modem is properly connected to the DTE, dial and/or leased lines, and ac outlet, press the modem's rear panel power switch to the ON position. The modem begins a power-up self-test. This test takes several seconds to perform, and verifies the operation of most hardware components within the modem. If successful, the LCD displays Power On Selftst Passed and continues to the Top-Level menu screen.

If a failure occurs during the self-test, the LCD may

display Power On Selftst Failed for several seconds. The LCD then may display the Top-Level menu screen with the message Power on Fail appearing on the top line of the LCD. Although a failure has occurred, the modem may attempt to operate. If it does, you can activate a more thorough self-test using the Test branch. Refer to Chapter 6, Test Branch.
