Introduction
Utilities board
SMUC environmental monitoring
The following environmental conditions are monitored:
• ASIC installation error sensing
• FPGA configuration and status
• Thermal sensing
• Fan Sensing
• Power failure sensing
• 48-V failure
• 48-V maintenance
• Ambient air temperature sensing.
• Power-on
