Online UPS unit must be operated according to the product manual and instructions. Otherwise, improper use of the UPS may cause safety risks. The contact resistance caused by the virtual connection of the cable connector is too large, and the contact surface is seriously oxidized after the temperature rises, which will cause the contact resistance to become larger, and eventually lead to electrical ignition or even arc pulling, igniting combustible materials nearby, causing fire. After receiving the purchased UPS power supply product, the user will see the complete and detailed UPS installation requirements and precautions provided by the manufacturer. Only when the requirements are met can the UPS power supply system work properly. Of course, the user can also contact the buyer to provide online guidance service to ensure the normal operation of the online UPS unit.
Recently, extreme heat in California cost Twitter a key data center. As data centers become more and more dependent, temperature control and security at these centers is especially important. Once considered "redundant," data centers can come in handy at special times like this. Twitte, like all major social media platforms, relies on data centers, which are basically huge warehouses filled with computers, including servers and storage systems. Controlling the temperature of these centres is crucial to ensuring that computers do not overheat and fail. And on September 5, Twitter experienced a loss of its Sacramento (SMF) data center area due to extreme weather. This unprecedented event resulted in a complete shutdown of SMF's physical equipment. Large tech companies often have multiple data centers, in part to ensure that their services can stay online in the event of a center failure, known as redundancy. Twitter is in a "non-redundant state" due to the Sacramento outage. Fortunately, Twitter's data centers in Atlanta and Portland are still up and running, but Twitter warns that if it loses one of those remaining data centers, it may not be able to provide traffic to all Twitter users.
As the center of data storage, the importance of the computer room is self-evident. If the computer room fails, all the data may be lost, causing irreparable consequences. The security of the computer room has become a concern of many people. And the room temperature is too high in addition to external involvement, its own causes will be what? What are the solutions and countermeasures?
Normally, the temperature in the equipment room is about 23 ° C and the humidity is about 45%. If the air conditioner in the equipment room is faulty, the temperature in the equipment room will rise to more than 28 ° C. In this case, it is very likely that the server in the machine room will break down due to high temperature.
Vibration resistance of uninterruptible power supply and maintenance space vibration resistance of uninterruptible power supply products and equipment, horizontal is 0.5G, vertical is about 0.25G. The maintenance space of the UPS is at least 1200mm in the front, 100mm in the back, and 500mm in the top. Uninterruptible power supply products after such careful transportation and installation, and then installed to a suitable position, in order to better play its role, to provide more stable and reliable power for our electronic equipment.
Power consumption (or power rating) is usually indicated on the equipment. In this case, the rated power of all connected UPS unit should not exceed the output power of the UPS. This approach is often referred to as matching the power output of the UPS to the power consumed by the load. However, the starting power of some devices is 3-5 times of the rated power (for example, the rated power of the printer is 200W, so the load matching calculation needs to be converted to 5 x 200W = 1000W). With the exception of the printer, the starting power of other external computer devices is usually slightly higher than the rated power. Therefore, it is recommended that the load match 80% of the UPS output power.
