LED Sequences
The LEDs on the Switch Module help to indicate problems that
occur.
During the power-up sequence, the DEFINITY Extender 1100
System performs a self-test, indicated by a sequence of 1 yellow,
and 8 red flashes, followed by 1 green flash, fast blinking red
flashes for about 6 seconds, 3 green flashes and 1 red flash. That
series of flashes is followed by 3 sets of 8 yellow flashes.
Table 4-1 and Table 4-2 illustrate a detailed description of the LED
sequences.
If your Switch Module power up LED sequence repeats itself, the
last sequence displayed represents the test failure that occurred.
See Table 4-1 for failure description. Power down the unit, and
retry. If error persists, contact the Lucent Technologies Helpline.
