The city power is normal, people can surf the Internet, but UPS always jump to the battery power supply mode. And in this mode there is always a beep. We immediately organized the staff to check the circuit and analyze the cause of the failure. Finally it linked to the vertical air-conditioning room, every time start the air conditioning for a while, it automatically converted into battery powered. Obviously this is due to the impact of high power air conditioning to the city power output. But they are separated in two power supply, from the switchboard of different distribution room, how will interfere with each other?
With this question, the electrician followed the wire to open the ceiling, floor, junction boxes, etc.. in order to figure out that if there is a place where the circuit is falsely connected, and finally found that the zero line and the ground wire are connected together. So fuzzy interference can have an impact on the high frequency online UPS, it really is a precision device.
We decided to separate the ground wire of the air condition. After separating the zero line and the ground wire, and then start the air conditioning, found the UPS never jump again. So why this problem did not appear before? We believe that is the weather is too hot, air conditioning full load operation, which increased power consumption.
The quality of power supply is very important to the stability and security of the enterprise network. However, there are many properties of network power security, such as high performance, scalability, reliability, functionality, accuracy and availability, etc.. In order to make the enterprise network power supply can continue to run steadily, in addition to the usual use of norms, the periodic use of a variety of testing tools for the implementation of maintenance testing of the network environment is necessary. The entire room power supply safety system, need technical personnel to maintain seriously, and to do a good job of routine investigation, timely detect the problems, analysis of the impact caused by unplanned downtime.
