Technical Reference Guide
In general, the LEDs operate as follows:
•
after the card is plugged in, the LEDs (a-e) are turned on by the power-
up circuit. The clock controller LED is independently controlled by its
own microprocessor
•
after initialization, the LEDs (a-e) flash three times (0.5 seconds on, 0.5
seconds off) and then individual LEDs will go into appropriate states, as
shown in Table •.
