Problems solved by technology

[0007] Lack of rigorous testing methods and procedures. Unlike single-node desktop servers, single-node servers are only connected to one monitor, so you can only observe the status of one node, while multi-node cabinets have more than 30 nodes, all connected to the It is unrealistic to observe the display at the same time, so the failure judgment of the electrostatic test has caused a big problem. It needs to be observed, so the grounding restart, disk drop, and blue screen waiting status

Embodiment Construction

[0024] The present invention will be described in further detail below according to the accompanying drawings.

[0025] 1) Improved grounding system

[0026] Use double grounding copper pillars and connect them with a copper plate to reduce the grounding impedance.

[0027] like figure 1 and figure 2 As shown, an aluminum plate with a thickness of 0.6cm, a length of 2.5m, and a width of 1.5m is used as the grounding reference plane, a copper core cable with an inner diameter of 4mm is used as the grounding wire, and the grounding stake uses two copper columns with a diameter of 2cm and a length of 40cm; Small grounding impedance, the two copper columns are fixed with a copper plate, and the distance between the two copper columns is 15cm. Each grounding copper column and the copper plate are pinned to a plane to increase the contact area and reduce the grounding impedance; the entire grounding copper column is buried 50cm into the soil; according to the electrostatic failu...

Abstract

The invention provides a static test method for a large-sized rack server and relates to the field of static testing for multi-node cabinet servers. Two copper ground posts and a copper plate are used for interconnection, and ground impedance is decreased; the copper ground posts are 15cm spaced; each of the copper ground posts and the copper plate is provided with a plane; a temporary failure state and a permanent failure state are provided according to static failure; a node discharging region and a non-node discharging region are separated; failure is judged by direct observation and network pin reading.

Description

technical field [0001] The invention relates to the field of electrostatic testing of multi-node cabinet servers, in particular to an electrostatic testing method for large-scale Rack servers. Background technique [0002] Static electricity is the most common cause of electronic equipment failure. The country has also formulated strict national standards for static electricity testing, which is also an important part of electromagnetic compatibility technology. It mainly studies the ability of IT equipment to resist electrostatic interference. [0003] At present, the electrostatic test of desktop equipment is very common, and a very careful test method and process have been formed, but the problems existing in the electrostatic test of multi-node rack-mounted servers are: [0004] Question 1: [0005] There are almost no static sites for floor-standing large-scale servers in each laboratory, even if it is difficult to fully meet the national standards; [0006] Question ...
