Abstract
The invention provides a static test method for a large Rack server, which relates to the field of static test of a multi-node Rack server.
Description
Technical field
It is specifically a kind of to be used for large-scale Rack the present invention relates to the electrostatic test field of multinode Cabinet-type server
The static electricity testing method of server.
Background technology
Electrostatic phenomenon is most common reason in electronic failure, and country also formulates electrostatic test strict country's mark
Standard, is also a pith in electromagnetic compatibility technology, and main research information technoloy equipment supports antistatic ability.
At present, the electrostatic test of table top device is very common, and forms very careful method of testing and flow, still
The problem of electrostatic test of multinode Cabinet-type server is present be：
Problem 1：
Each laboratory almost electrostatic place without console mode large server, is difficult to comply fully with national mark even if having
It is accurate；
Problem 2：
Lack careful method of testing and flow, different from single node desktop server, single-unit point server is only connected
One display, so the state of a node can only be observed, and more piece point cabinet has more than 30 nodes, all shows in connection
Show device, observe simultaneously, but it is unrealistic, so the problem of judging just to generate very big to the failure of electrostatic test, since it is desired that seeing
Restarting for all nodes is examined, falls disk, blue screen waits situation.Accordingly, it would be desirable to a careful ineffectiveness determination methods；
Problem 3：
To reduce testing time and reduction testing expense, the testing process for setting up a pool is very important.
The content of the invention
The problem of in order to solve in background above technology, the present invention proposes a kind of electrostatic test side of large-scale Rack racks
Method.
Fundamental novel features are：
1）, improved earthed system
We are interconnected using double ground connection copper posts, then with one piece of copper coin, reduce impedance ground.We are thick using 0.6cm, long
2.5m, wide 1.5m aluminium sheet are as ground reference plane, using internal diameter 4mm copper core cable as earth lead, and ground stud
Use two diameter 2cm, long 40cm copper post.To reduce impedance ground, two copper posts are fixed using one piece of copper coin, two copper posts
Spacing 15cm.Each ground connection copper post and the ground square cotter of copper coin contact go out a plane, and enlarged contact areas reduces impedance ground.
Whole ground stud buries 50cm；
2）, careful electrostatic failure determination methods
Rack racks are different from the rack server of single node, when doing electrostatic test, show if we only connect one
Show device, we can only observe the state of a node, and more than 30 nodes are all connected upper display, observe simultaneously, again
It is unrealistic.The situation that we fail according to electrostatic is divided into two states, temporary failure and eventual failure, and node type is put
Electricity and the electric discharge of not a node type are distinguished, by the way of directly observation and network pin are read, and carry out ineffectiveness judgement.
In testing, it is related to atmospherical discharges and contact discharge, multiple grades is designed into again, we uses the side planned as a whole
Method, sequencing of cleverly arranging can reach the purpose for saving testing time and testing expense.
The beneficial effects of the invention are as follows：
1）, the present invention propose a kind of static electricity testing method for grounding multinode large server rack, reach simultaneously
Far superior to national standard；Reduce testing time and reduction testing expense；
2）, the present invention propose a kind of ineffectiveness judgement of electrostatic test for grounding multinode large server rack
Method, is easily realized, and meet national standard.
Brief description of the drawings
Accompanying drawing 1 is the earthed system schematic diagram of the present invention.
Accompanying drawing 2 is the right view of copper post work.
Accompanying drawing 3 is the schematic diagram that careful electrostatic failure determination methods are divided into two states.
Accompanying drawing 4 is the test flow chart planned as a whole.
Embodiment
The present invention is described in further detail below according to accompanying drawing.
1）, improved earthed system
Interconnected using double ground connection copper posts, then with one piece of copper coin, reduce impedance ground.
As depicted in figs. 1 and 2, it is thick using 0.6cm, long 2.5m, wide 1.5m aluminium sheet is as ground reference plane, using interior
Footpath 4mm copper core cable is as earth lead, and ground stud uses two diameter 2cm, long 40cm copper post；To reduce ground connection resistance
Anti-, two copper posts are fixed using one piece of copper coin, two copper post spacing 15cm.Each ground connection copper post and the ground square cotter of copper coin contact go out
One plane, enlarged contact areas reduces impedance ground；Whole ground connection copper post is buried 50cm；The situation point failed according to electrostatic
Into two states, temporary failure and eventual failure, and node type electric discharge and the electric discharge of not a node type are distinguished, using directly sight
The mode read with network pin is examined, ineffectiveness judgement is carried out.
2）, careful electrostatic failure determination methods.
As shown in figure 3, in testing, being related to atmospherical discharges and contact discharge, multiple grades are further related to, pool is used
Method, sequencing of arranging can reach the purpose for saving testing time and testing expense.
In testing, it is related to atmospherical discharges and contact discharge, multiple grades is designed into again, we uses the side planned as a whole
Method, sequencing of cleverly arranging can reach the purpose for saving testing time and testing expense.As shown in figure 4, the present invention is used
First atmospherical discharges, rear contact discharge, first low-voltage, rear high voltage, and combine failure determination methods, and accidental phenomenon determination methods
Etc., integrate, form the testing process of a pool.
