Embodiment 1

[0017] Add a spare battery to the mainboard. When the mainboard is disconnected from the external AC power supply, the mainboard will automatically switch to the spare battery for power supply. The spare battery can ensure the normal power consumption of the control circuit of the fault indicator light on the mainboard, so that the mainboard fault indicator light will remain normal. On state; the main board is charging the backup battery under normal power supply state.

Embodiment 2

[0019] Add a spare battery to the motherboard, and set up AC power supply circuit, battery power supply circuit, automatic switching circuit, fault indicator light control circuit and fault indicator light; the AC power supply circuit is mainly responsible for supplying power to the fault indicator light control circuit when the main board is working normally and Each fault indicator light is powered, and at the same time, the battery is charged for the battery power supply line to ensure that the battery power is sufficient; the battery power supply line is mainly responsible for providing sufficient power to the fault indicator light control circuit and each fault indicator light when the main board fails; The switching line is mainly responsible for the automatic switching of the AC power supply line and the battery power supply line; the fault indicator control circuit is mainly responsible for monitoring the faults sent by the BMC control chip in the motherboard, and perfor...

Embodiment 3

[0021] Add two parallel spare batteries to the motherboard, and set up AC power supply circuit, battery power supply circuit, automatic switching circuit, fault indicator control circuit and fault indicator light; among them, the AC power supply circuit is mainly responsible for controlling the fault indicator light when the motherboard is in normal operation. Line power supply and power supply for each fault indicator light, and also charge the battery for the battery power supply line to ensure sufficient battery power; the battery power supply line is mainly responsible for providing sufficient power for the fault indicator light control line and each fault indicator light when the main board fails. Power; the automatic switching line is mainly responsible for the automatic switching of the AC power supply line and the battery power supply line; the fault indicator control circuit is mainly responsible for monitoring the faults sent by the BMC control chip in the motherboard,...

Abstract

The invention discloses an automatic electrifying method for keeping an alarm indicating lamp in a mainboard normally on, and belongs to the field of electronic equipment. The method comprises the following steps that a standby battery is additionally arranged in the mainboard, after an external AC power source is disconnected from the mainboard, the mainboard is automatically switched to the standby battery to be provided with power, and the standby battery guarantees normal electricity utilization of a control line of a fault indicating lamp in the mainboard. According to the automatic electrifying method for keeping the alarm indicating lamp in the mainboard normally on, compared with the prior art, it is guaranteed that the fault indicating lamp is normally on after the AC power source is disconnected, the defect that the fault indicating lamp can be only observed under the electrifying condition of the mainboard through a universal server is overcome, and an engineer is helped to quickly position faults and solve problems.

Description

[0001] technical field [0002] The invention relates to the field of electronic equipment, in particular to an automatic power-on method for ensuring that an alarm indicator light in a main board is always on. Background technique [0003] With the continuous expansion of the application scope of the Internet, many businesses in people's work and life are showing the development trend of informatization. The demand for network servers is also increasing, and various high-density cabinet servers have come out one after another. This type of server cabinet is composed of many computing nodes (that is, a single server) and related management units and monitoring units. This type of server cabinet maximizes the computing power of the system. However, due to the large number of computing nodes in this kind of high-density server system, once a failure occurs, it will also bring great difficulties to the positioning and analysis of engineers. [0004] Common servers also have f...
