The management power is used to directly power the devices connected to the front-blade I2C
bus, namely for serial EEPROM, temperature sensors and I/O extender device.
+12 V payload power is the source for the onboard DC to DC converters needed for the RTM
payload.
4.8.1 Power-good Indication
The RTM FPGA includes logic to generate an overall power-good signal to the front-blade based
on the state of the various power supplies. Since this signal comes from the FPGA, it also serves
as an indication that the FPGA configuration has completed.
4.8.2 Power Requirements
The table below summarizes the power requirements of the RTM-ATCA-F125.
