ADTRAN TSU 120e user manual Power Up Testing, Self-Test, Initialization, Set User Passcode

Chapter 2. Installation

Power Up Testing

When shipped from the factory, the TSU 120 is set to factory default conditions. At the first application of power, the unit automatically executes a memory self-test. A full self-test can be run from the front panel. A passcode and Unit ID may be set using the UTIL MENU.

Self-Test

Upon a power-up, the LCD displays MEMORY TEST NOW TESTING and the Test LEDs are illuminated. When the self-test is com- pleted with no failures detected, the OK LED lights up and the LCD momentarily displays MEMORY TEST(S) PASSED. If a fail- ure is detected, a list of failures is displayed in the LCD win- dow.

Initialization

Set User Passcode

The TSU 120 is designed to operate with or without the use of a passcode. The default condition is without a passcode.

If the unit is to be remotely accessed using T-WATCH Pro, you must enter a passcode. When managing a number of units, the passcode can be the same for all the units.

The passcode should be a number easily remembered. Once entered, the passcode is required to access any operation other than viewing. See Change/Set a Passcode on page 6-4for details.

Set Unit Identification

The Unit ID sets the unit to respond to remote control (con- trolled by a device other than the front panel or terminal). If no Unit ID is recorded it is not possible to operate from any remote control device, including the local PC for T-WATCH Pro or SNMP. See Unit ID on page 6-4for details.
