POWER-UP TESTING AND INITIALIZATION
When shipped from the factory, the T1 ESF CSU ACE is set to
factory default conditions; it is not initialized. At the first
application of power, 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
