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
The present invention relates to the electrostatic test field of multinode Cabinet-type server, specifically a kind of static electricity testing method for large-scale Rack server.
Background technology
Electrostatic phenomenon is modal reason in electronic failure, and country also formulates strict national standard to electrostatic test, 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 defines very careful method of testing and flow process, but the electrostatic test Problems existing of multinode Cabinet-type server is:
Problem 1:
Each laboratory does not almost have the electrostatic place of console mode large server, is difficult to meet national standard completely even if having;
Problem 2:
Lack careful method of testing and flow process, different from single node desktop server, single node server only connects a display, so can only observe the state of a node, and multinode rack has more than 30 nodes, all connect display, observe simultaneously, unrealistic again, so judge just to create very large problem to the inefficacy of electrostatic test, need to observe so restarting of ground connection, fall dish, blue screen waits for situation.Therefore, the ineffectiveness determination methods that careful is needed;
Problem 3:
For reducing the test duration and reducing testing expense, set up a testing process planned as a whole and be very important.
Summary of the invention
In order to solve the problem in above background technology, the present invention proposes a kind of static electricity testing method of large-scale Rack rack.
Fundamental novel features is:
1) earthed system, improved
We use two grounding copper post, then use one piece of copper coin interconnected, reduce impedance ground.We use 0.6cm thick, long 2.5m, and the aluminium sheet of wide 1.5m, as ground connection reference planes, use the copper core cable of internal diameter 4mm as earth lead, and ground stud uses two diameter 2cm, the copper post of long 40cm.For reducing impedance ground, two copper posts use one piece of copper coin to fix, two copper intercolumniation 15cm.The ground square cotter that each grounding copper post contacts with copper coin goes out a plane, enlarged contact areas, reduces impedance ground.Whole ground stud buries 50cm;
2), careful electrostatic inefficacy determination methods
Rack rack is different from the posture server of single node, and when doing electrostatic test, if we only connect a display, we can only observe the state of a node, and more than 30 nodes are all connected upper display, observe simultaneously, unrealistic again.The situation that we lost efficacy according to electrostatic is divided into two states, temporary inefficacy and eventual failure, and node type electric discharge and the electric discharge of not a node type are distinguished again, the mode that employing is directly observed and network pin reads, carries out ineffectiveness judgement.
In testing, relate to atmospherical discharges and contact discharge, be designed into again multiple grade, we use the method for pool, sequencing of arranging cleverly, can reach the object of saving test duration and testing expense.
The invention has the beneficial effects as follows:
1), the present invention proposes a kind of static electricity testing method for grounding multinode large server rack, reaches and is far superior to national standard; Reduce the test duration and reduce testing expense;
2), the present invention proposes a kind of method of the ineffectiveness judgement of electrostatic test for grounding multinode large server rack, easily realizes, and meets national standard.
Accompanying drawing explanation
Accompanying drawing 1 is earthed system schematic diagram of the present invention.
Accompanying drawing 2 is right views of copper post work.
Accompanying drawing 3 is schematic diagram that careful electrostatic inefficacy determination methods is divided into two states.
Accompanying drawing 4 is the test flow charts planned as a whole.
Embodiment
With reference to the accompanying drawings the present invention is described in further detail below.
1) earthed system, improved
Use two grounding copper post, then use one piece of copper coin interconnected, reduce impedance ground.
As depicted in figs. 1 and 2, use 0.6cm thick, the aluminium sheet of long 2.5m, wide 1.5m, as ground connection reference planes, use the copper core cable of internal diameter 4mm as earth lead, and ground stud uses two diameter 2cm, the copper post of long 40cm; For reducing impedance ground, two copper posts use one piece of copper coin to fix, two copper intercolumniation 15cm.The ground square cotter that each grounding copper post contacts with copper coin goes out a plane, enlarged contact areas, reduces impedance ground; Whole grounding copper post buries 50cm; Be divided into two states, temporary inefficacy and eventual failure according to the situation that electrostatic lost efficacy, node type electric discharge and the electric discharge of not a node type are distinguished again, the mode that employing is directly observed and network pin reads, carries out ineffectiveness judgement.
2), careful electrostatic inefficacy determination methods.
As shown in Figure 3, in testing, relate to atmospherical discharges and contact discharge, relate to again multiple grade, use the method planned as a whole, arrangement sequencing, can reach the object of saving test duration and testing expense.
In testing, relate to atmospherical discharges and contact discharge, be designed into again multiple grade, we use the method for pool, sequencing of arranging cleverly, can reach the object of saving test duration and testing expense.As shown in Figure 4, this patent adopts first atmospherical discharges, rear contact discharge, first low-voltage, rear high voltage, and in conjunction with inefficacy determination methods, and accidental phenomenon determination methods etc., integrate, form a testing process planned as a whole.
Claims (4)
1. for a static electricity testing method for large-scale Rack server, it is characterized in that improving earthed system, use two grounding copper post, then use one piece of copper coin interconnected, reduce impedance ground; Situation about losing efficacy according to electrostatic is again divided into two states, temporary inefficacy and eventual failure, and node type electric discharge and the electric discharge of not a node type are distinguished again, the mode that employing is directly observed and network pin reads, carries out ineffectiveness judgement.
2. method according to claim 1, is characterized in that, uses 0.6cm thick, and the aluminium sheet of long 2.5m, wide 1.5m, as ground connection reference planes, use the copper core cable of internal diameter 4mm as earth lead, and ground stud uses two diameter 2cm, the copper post of long 40cm; For reducing impedance ground, two copper posts use one piece of copper coin to fix, two copper intercolumniation 15cm; The ground square cotter that each grounding copper post contacts with copper coin goes out a plane, enlarged contact areas, reduces impedance ground; Whole grounding copper post buries 50cm.
3. method according to claim 1 and 2, is characterized in that in testing, relates to atmospherical discharges and contact discharge, relates to again multiple grade, uses the method planned as a whole, and arrangement sequencing, can reach the object of saving test duration and testing expense.
4. method according to claim 3, is characterized in that adopting first atmospherical discharges, rear contact discharge, first low-voltage, rear high voltage, and in conjunction with inefficacy determination methods, and accidental phenomenon determination methods, integrate, form a testing process planned as a whole.
