Problems solved by technology

When there are many servers in the data center, if the servers work in standby mode for a long time, the power consumption caused by non-business load will be a great waste
[0003] In addition, the BMC has a debugging serial port (UART) in the form of a USB interface. If the BMC network function or the entire BMC system hangs up, the operation and maintenance personnel will not be able to remotely manage the server. They must enter the computer room through the BMC serial port on the server. Perform function debugging, even restart BMC
BMC serial ports usually exist in the form of DB-9, earphone port, RJ45 interface, etc., which not only take up space, but also require special cables for debugging, which is very inconvenient

Embodiment 1

[0025] Such as figure 1 As shown, this embodiment provides a power management device, including the following structure:

[0026] A power line carrier communication module (PLC) is added to the alternating current (AC) side of the power supply module (PSU), and the power line carrier communication module outputs two GPIOs and a serial port (UART) to the direct current (DC) side. The GPIO and the serial port are both TTL level; the power line carrier communication module realizes the communication with the remote equipment interconnected with the power line by sending the carrier wave to the power line and detecting the power line carrier on the AC side.

[0027] Use an optocoupler (OC) between the power line carrier communication module and the system DC circuit, such as figure 2 As shown, two GPIOs (GPIO_1, GPIO_2) and one serial port of the power line carrier communication module are electrically isolated from the DC power of the system; on the DC side, two GPIOs of VR_EN ...

Abstract

The invention provides a power supply management device which comprises a power line carrier communication module which is arranged on the alternating current side in a power supply module, and the direct current side of the power line carrier communication module is provided with two GPIO ports and a serial port; and the power line carrier communication module is in communication connection with remote equipment through a power line. According to the power supply management device of the invention, remote control of a standby power supply is realized, power consumption of a system in a standby mode is avoided, and reduction of energy consumption of a data center is facilitated; meanwhile, when a BMC network function is abnormal, operation and maintenance personnel can carry out BMC remote serial port debugging through power line carrier communication; when a BMC is suspended, the operation and maintenance personnel can also perform remote reset operation of the BMC through power line carrier communication; and the power line carrier communication module is utilized to communicate with the remote equipment, so that machine room wiring does not need to be increased.

Description

technical field [0001] The invention belongs to the technical field of servers, and in particular relates to a power management device. Background technique [0002] The power system of the data center is generally divided into alternating current (AC) output by the transformer and direct current (DC) inside the server. The power supply unit (PSU) completes the conversion from alternating current to direct current; the direct current inside the server is divided into standby power (Standby Power) and system power supply (Core Power), the standby power supply is the working power supply of the management unit, and it will be powered on automatically when the AC power is turned on; the management unit mainly includes a baseboard management controller (BMC), a programmable logic device (CPLD), a chipset (PCH ) and onboard sensors, etc., are used to facilitate remote server management, monitoring, installation, restart and other operations. When there are many servers in the da...
