Abstract
An information handling system having a plurality of blade server modules (BSMs) and power supply units (PSUs) uses a module monitor board (MMB) to monitor and control a power budget of the PSUs by each individual BSM requesting authorization from the MMB in order to power ON and boot-up. A blade management controller (BMC) may communicate with the MMB over a communications bus. However, if the firmware application controlling the BMC has been corrupted the BMC it may run in a 'boot block' mode and not contain the intelligence necessary to obtain power ON authorization from the MMB. A single, existing input-output (I/O) line from the MMB to the BMC may be utilized to indicate power ON authorization for the respective BSM. The MMB and BMC may be adapted for preventing the BSM from powering ON without proper authorization from the MMB and that the BMC will always power ON the BSM when enough power is available from the PSU. A dual-use of the I/O line may be used for providing a pseudo-communications channel between the MMB and the BMC when the BMC may be in the BOOT BLOCK mode.
