Abstract
The invention discloses a method for solving fan electrification maintenance, which belongs to the field of rack cabinet systems. The method comprises the following steps: firstly, determining a fan power supply input end of a fan control panel, and connecting the fan power supply input end with a power supply copper bar through a power supply adapting cable; installing a total overcurrent protection module at the fan power supply input end, and ensuring that an overcurrent point is 1.5 times of the total rated currents of nine fans; dividing 9 power supply branches from the output end of the total overcurrent protection module, connecting a branch overcurrent protection module onto each power supply branch, ensuring that the overcurrent point of the overcurrent protection module of each branch is less than 1.5 times of the rated current of the fan, connecting an output end of the overcurrent protection module of each branch with a fan connecting port, and connecting the output end of the overcurrent protection module of each branch with the corresponding fan through a fan adapting wire. By utilizing the method, the fan electrification maintenance is realized, and the maintainability is strengthened; when one fan on a fan wall is damaged, a fan main body and surrounding circuits cannot be influenced in an electrification changing process.

Concentrated radiating mode is to dispose a fan wall at the rear portion of whole rack, fan by fan wall is in the rear of cabinet exhausting, the anterior air draught of rack, thus form an air channel at the front and rear of computing node, heat is taken out of by distinguished and admirable, guaranteed the normal operation of node.Because the fan on fan wall is more, generally adopt 9 fans to form one group.When service time, extend, the situation of abnormal work may appear in fan, in order to guarantee the normal heat radiation of node, just need under charged condition, abnormal fan be taken off, and changes the fan of normal operation.But in general charged for replacement fan process, have hot-swappable action, can cause damage to circuit and fan body on every side.
Summary of the invention
But technical assignment of the present invention is to provide a kind of method that solves the fan power-on serving.
Technical assignment of the present invention realizes in the following manner, and the method step is as follows: at first, determine the fan of fan control board for electrical input, be connected with the copper bar of powering by the power supply cable of transferring; Then at the fan control board input end, a total overcurrent protection module is installed, guaranteed that flow point was 1.5 times of 9 total specified electric currents of fan; Separate 9 power supply branch roads at total overcurrent protection module output terminal; connect a branch road overcurrent protection module on each power supply branch road; the mistake flow point that guarantees each branch road overcurrent protection module is no more than 1.5 times of fan rated current; the output terminal of each branch road overcurrent protection module connects a fan connectivity port, by the fan patchcord, is connected on corresponding fan.
Described total overcurrent protection module is the ISL6115 chip.
Described branch road overcurrent protection module is the TPS2491 chip.
But a kind of method that solves the fan power-on serving of the present invention compared to the prior art, realizes the power-on serving of fan, strengthens maintainable.Certain fan on fan wall damages, and in the charged for replacement process, can guarantee in hot-swappable process, can not impact fan body and All other routes on every side.
The accompanying drawing explanation
But accompanying drawing 1 is a kind of enforcement status architecture schematic diagram that solves the method for fan power-on serving;
In figure: 1, fan control board, 2, total overcurrent protection module, 3, fan is for electrical input, 4, the branch road overcurrent protection module, 5, fan.
