T1 ESF CSU ACE User Manual Chapter 2. Installation

POWER-UP TESTING AND INITIALIZATION

When shipped from the factory, the T1 ESF CSU ACE is set to factory default conditions. When power is applied, the unit automatically executes self test, followed by an initialization sequence that sets up the unit.

Self Test

Upon a power-up or self test, the LCD displays ADTRAN T1 ESF CSU ACE INITIALIZING and the LEDs illuminate momentarily. When the self test is completed with no failures detected, the LCD momentarily displays ALL TESTS PASSED. If a failure is detected, it is displayed in the LCD window. The automatic self test procedure consists of the following steps:

1.Board level tests - RAM tests; EPROM checksum

2.Unit level tests - Front panel LED verification
