Server rack predictive maintenance method

A server rack predictive maintenance method, comprising:

• supplying, by a fan, air to a server and a network equipment installed in an internal space of a server rack;
• detecting that the server rack is in a normal operating state when internal temperature and humidity of the server rack are maintained constant while supplying, by the fan, the air to the server and the network equipment;
• supplying, by a main wire, power to the fan, the server, and the network equipment;
• collecting a power value consumed in the main wire for supplying the power to the fan, the server, and the network equipment when the server rack is in the normal operating state;
• collecting a vibration value generated by the server rack when the server rack is in the normal operating state;
• setting an average current value of the server rack based on the collected power value and setting an alarm current value to be smaller than the set average current value;
• setting an average vibration value of the server rack based on the collected vibration value and setting an alarm vibration value to be larger than the set average vibration value;
• measuring real-time power values consumed by the main wire while supplying, by the fan, the air to the server and the network equipment;
• measuring real-time vibration values of the server rack while supplying, by the fan, the air to the server and the network equipment;
• detecting that the server rack is in an abnormal state when at least one measured real-time power value among the measured real-time power values is less than the alarm current value or when at least one measured real-time vibration value of the server rack among the measured real-time vibration values of the server rack exceeds the alarm vibration value;
• detecting that the server rack is in a risk state when the at least one measured real-time power value is less than the alarm current value and the at least one measured real-time vibration value of the server rack exceeds the alarm vibration value;
• and
• alarming that the server rack is in the abnormal state of the server rack or in the risk state of the server rack.
