Problems solved by technology

[0005] Because the existing technology only controls the power-on sequence, it often causes the entire system to work in a power overload state and restart due to insufficient power, which is unacceptable for core equipment

Embodiment Construction

[0022] Throughout the specification, the preferred embodiment and examples shown should be considered as exemplifications of the invention and not as limitations.

[0023] The system structure diagram of the preferred embodiment of the present invention is shown in Figure 1, the system includes a power supply module, a monitoring unit, a memory and a power-on control circuit,

[0024] After the newly inserted board is powered on, the memory storing the power consumption information of the inserted slot is powered on first, and the monitoring unit can read the power consumption parameters from the newly inserted board, and compare it with other power-on sheets read previously. The power consumption of the board is summed to check whether the required power of the system is greater than the rated power of the power supply. If not, a power-on command is issued to the power-on control circuit of the corresponding slot; otherwise, no power-on command is issued and an alarm message i...

Abstract

This invention discloses a single board and a method for controlling it to be electrified, in which, a single board is plugged and a monitor unit reads power loss information of the board and sums it and that of the single board to get the system power loss requirement, which is compared with the rating output power of the supply to present related control signals to the electrified control circuit based on the compared result. If the requirement is not greater than the rating power of the supply, the board is electrified.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a single board and a method for controlling its power-on. Background technique [0002] With the continuous improvement of network bandwidth requirements, we have higher and higher requirements for the processing capabilities of high-end equipment in the backbone core network. Taking high-end routers as an example, the port capacity is getting bigger and bigger. From the original 64K port to the current 10G port, the total switching capacity of the system has reached the T-bit level. The increase in bandwidth means that the power consumption of the system increases. The power supply of general carrier-grade products is subject to various restrictions, and it is impossible to increase it without limit, which has a great impact on the power supply of the system. [0003] High-end network equipment generally includes a motherboard and multiple boards. The pluggable bo...
