+3.3 V and +5 V dc monitor LEDs on A50/A60 CPU Module as shown in Figure 2-4
•
LEDs on DSP module as shown in Figure 2-5

To check all the outputs of the power supply, measure the dc voltages at the output lead
connectors with a DMM. The dc output voltages and lead color information is provided in
the module cover label of the power supply.
