The invention relates to a remote automatic alarm system for internal hardware operation faults of servers. The system comprises the servers to be monitored, a condition monitoring server, an alarm information sending device and a mobile phone, wherein the servers to be monitored, the condition monitoring server, the alarm information sending device and the mobile phone are in a local area network. A method of the system comprises the steps that (1) the devices of the whole system are debugged and connected; (2) a plurality of hardware scanning modules, a hardware scanning feedback data analysis module and fault information remote sending module are set in the condition monitoring server; (3) all the servers to be monitored are encoded, and all panel lamp condition data under the encoding are grouped; (4) the data are collected for analysis and judgment, and an alarm level is determined; (5) an alarm signal is sent; (6) alarm information is presented on the mobile phone. According to the remote automatic alarm system for the internal hardware operation faults of the servers, the abnormal condition of the hardware devices of the servers can be found and processed in time, so that the operation efficiency and maintenance efficiency of the servers are enhanced, and the disruption risk of the servers is lowered.
