Front panel cable for Supermicro SC512L chassis to a Via EPIA M10000 motherboard
The Supermicro chassis comes with a 16 way straight through cable from the front panel to the motherboard. The layout for this is not pin for pin compatible with a EPIA M10000 motherboard. This document describes a hand made replacement cable.
The Supermicro SC512L chassis comes with a front panel with a FP512 v3.0 front panel board.
This board provides:
- a power button
- a reset button
- a power LED
- a disk activity LED
- two NIC LEDS
- a fault LED
The EPIA M10000 motherboard can directly utilise the power/reset buttons, the power LED, and the disk activity LED. I chose to wire the 'stand-by' LED functionality onto the fault LED. The EPIA motherboard provides no headers for driving NIC LED's. Both NIC LEDS are not used.
Cable
Construct the cable using a short length of ribbon cable and two 16 pin IDC headers (with strain relief).
