Model 392xPlus Modem Power-Up
Once your modem is properly connected to the power supply, leased and/or dial lines, and the DTE, press the
modem's back panel power switch to the ON position. The modem begins a power-up self-test, in which all DCP
LEDs light. 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 displays Power On Selftst Failed for several seconds. The LCD
then displays 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 will attempt to operate. This allows you to activate a more thorough
self-test using the Test branch. Refer to Chapter 8, Test Branch, in Document No. 3920-A2-GH30.

Selecting Factory Configuration Options

After the modem passes the power-up self-test, configure it for operation using one of the six factory preset
configurations.
The Model 392xPlus modems have six factory preset templates that contain the most commonly used
configuration options (straps) for Synchronous Leased (Answer or Originate), Asynchronous Leased (Answer or
Originate), Trellis Multipoint (Control or Tributary), Asynchronous Dial, Synchronous Dial, and UNIX Dial
hardware network configurations. Your modem ships from the factory with the Synchronous Leased (Answer)
default configuration options stored in memory. If Synchronous Leased (Originate), Asynchronous Leased
(Answer or Originate), Trellis Multipoint (TMp) (Control or Tributary), Async Dial, Sync Dial, or UNIX Dial is
more appropriate for your configuration, then you must change the factory setting using either the modem's DCP
(as described in the following sections) or the AT command set.
The purpose of having preset configurations is so that you can have a "head start" in getting your modem
operating and reducing the amount of time required to configure your modem. For a better understanding of DCP
operation and factory preset configuration options, refer to Chapter 5, Configure Branch, in Document No.
3920-A2-GH30.
