Purpose
The UPM Diagnostic reads the power supply information from the UPM board.
The I/O Status test checks for the status of the chassis power supply, temperature of the chassis power supply, isolated 5 volts, FPGA initialization, flash power, RF NB board presence, RF MNS board presence, RF NB cable presence, RF MNS cable presence, unblank cable presence, RF NB negative 12 volt status, and RF MNS negative 12 volt status.
The Analog Data test reads the power supply information from the UPM board every 5 seconds for the specified test duration (maximum 300 seconds). No error messages are logged for failing power supplies, because the applications software logs these errors automatically.
