Option “4” Display IPMI EEPROM Information

This command displays the contents of the IPMI FRU EEPROM which holds the Part number and serial

number information as well as the full IPMI FRU header. Note: Although IPMI is not implemented in all

versions the IPMI EEPROM is always present.

Option “F” Force Software Reset

This command resets the PSOC device and restarts the firmware. As a result power will be toggled off then

on, effectively resetting the PMC and PLX controller. Re-initialization of the PXL and PMC may be

needed to continue operation. To prevent accidental execution the user is prompted to confirm this

command should be run.

Option “L” Load New Firmware via UART (Com Port)

This command updates the PSOC firmware over the serial interface. To prevent accidental execution the

user is prompted to confirm this command should be run.

Option “O” Force Secondary Power Off

This command turns off the 3.3V and 5V power to the PMC and the power to the PLX Bridge chip. The

+12V and -12V power is still supplied to the PMC. There is no command to turn power on. To prevent

accidental execution the user is prompted to confirm this command should be run.

Option “N” Resume Normal Fan Operation

This command returns the fan to normal operation after the fan override commands were executed. The fan

control algorithm will resume operation.

Option “–“ Override Fan – Decrease RPM

This command decreases the fan PWM by 10%, reducing the fan speed. This overrides the normal fan

operation and the fan control algorithm will not execute until command “N” is run.
