Method for testing output switching capability of power supply units of smart rack

Abstract

The invention discloses a method for testing the output switching capability of power supply units (PSU) of a smart rack. Scripts are compiled in the expect language, a rack manage controller adjusts the voltage threshold from DC to AC, the threshold is lower than the present DC voltage, and the condition for automatically switching to AC output is met. After switching, a normal threshold is recovered, power output of the PSU is switched back to DC, so that repeated test in the next step can be carried out. The method is rapid, convenient, easy to operate and capable of avoiding manual mistakes, and can be used in the RACK to automatically test the output switching capability of power supply units for a long time, the testing accuracy and stability can be effectively ensured, test can be carried out under the unmanned on duty state, and labor and time are saved.

Description

technical field [0001] The invention relates to the technical field of server power supply, in particular to a method for testing the output switching capability of a power supply module of a high-density server cabinet, a method with strong practicability, high stability, and the ability to repeatedly verify RMC (rack management controller) control in a short period of time. A test method for the power supply mode switching capability of the power supply module. Background technique [0002] As all walks of life rapidly enter the era of big data, high-density cabinets have the advantages of small footprint, accommodating a large number of nodes, and carrying more data services at the same time, and are more and more applied in various industries. [0003] A high-density server cabinet Smart Rack usually contains 4 to 10 power supply modules (Power Supply Unit, PSU) of the same model, which form different modules according to the functions of the PSU. It is generally divide...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is: Aiming at the long discharge time of the power supply battery in the computer room, which is not easy to operate repeatedly, the present invention provides a method that can detect the ability of the RACK cabinet RMC to switch the power supply mode, and repeatedly adjust the power supply mode through the script written based on the Expect tool. Set the DC input voltage threshold to achieve the effect of simulating the battery discharge voltage drop. The switching capability of the RMC can be repeatedly tested and verified in a short period of time, and the stability of the switching power supply mode of the RMC can be verified.
