Abstract
A power control system for a server is disclosed. The power control system includes a power supply device, configured to provide a main power source and a standby power source; at least a hot swap controller, coupled to the power supply device; at least a peripheral unit, coupled to the power supply device via the hot swap controller; and a motherboard, coupled to the power supply device via the hot swap controller, and includes a logic unit, configured to disable or enable the hot swap controller; and a baseboard management controller, coupled to the logic unit, configured to transmit an AC power cycle signal to the logic unit to disable the hot swap controller, and to transmit a reboot signal to the logic unit to enable the hot swap controller.
Claims12
A power control system, for a server, comprising:
- a power supply device, configured to provide a main power source and a standby power source;
- at least a hot swap controller, coupled to the power supply device;
- at least a peripheral unit, coupled to the power supply device via the hot swap controller;
- and
- a motherboard, coupled to the power supply device via the hot swap controller, and comprising:
- a logic unit, configured to disable or enable the at least a hot swap controller;
- and
- a baseboard management controller, coupled to the logic unit, configured to transmit an AC power cycle signal to the logic unit to disable the hot swap controller, and to transmit a reboot signal to the logic unit to enable the hot swap controller;
- wherein the power supply device is utilized for providing the standby power source to the logic unit and the at least a hot swap controller is enabled after the AC power cycle of the motherboard is finished.
A power control method, for a server, comprising:
- transmitting an AC power cycle signal, by a baseboard management controller, to a logic unit;
- disabling, by the logic unit, at least a hot swap controller;
- and
- enabling the hot swap controller, by the logic unit, when the baseboard management controller transmits a reboot signal to the logic unit;
- wherein the hot swap controller is coupled to a power supply device to control a main power source and a standby power source from the power supply device;
- wherein the power supply device is utilized for providing the standby power source to the logic unit and the at least a hot swap controller is enabled after the AC power cycle of the motherboard is finished.
