Notes
The external power supply connectors are a 24-pin (J6) and an 8-pin (J5) molex connector as described
in Table 2.5 and Table 2.6. The +12V3 is used to power PES64H16 and downstream ports 1 through 5. The
+12V1 is used to power downstream ports 6 through 10. The +12V2 is used to power downstream ports 11
through 15.
The power on switch located at S3 can be used to control the supply power from the external power
supply connector. Add a shunt to W19 to enable power on switch.
Power Supply Minimum Load Connectors
To provide the minimum load requirement for each rail of the EPS12V supply, a 2-pin fan connector is
provided for connecting to an external power resistor for each rail.
