How to detect the cause of the problem in UPS Power supply
UPS power supply system plays an important power guarantee effect in various professional data centers. In order to provide uninterrupted power supply for the load, it must have the function of electric energy storage. Therefore, the battery has become an important part of the UPS power supply system. However, due to the handling of the battery itself, there are many UPS problems caused by the battery.Therefore, it is necessary to strengthen the understanding of the characteristics of the battery, correctly select and use the battery, and extend the service life of the battery as much as possible. At the same time, how to deal with the battery has become a key issue for various UPS manufacturers and professional users.
UPS is easy to occur, such as non-inverter, unstable voltage, no charging, unable to use municipal electricity, unable to start normally, unable to switch normally after start-up, frequent switching to bypass power supply mode in operation, damage of inverter drive tube and immediate shutdown of UPS when municipal power is interrupted, etc., and puts forward the measures that should be taken.
Fault analysis and maintenance of UPS power supply: first of all, repeated installation of WIN95, Windows3.2, DOS failed to solve, scanning found and cleared GRAVE virus, made many adjustments to the options in BIOSSETUP, but the fault still exists. Second, consider hardware failures. Consider the new parts first, because only the CPU and the motherboard are newly replaced, so two motherboards of the same model are replaced, and the fault still exists.
Replace memory CPU found, all normal. And replaced with the Asustek TXP4 motherboard, not only not, but also can not boot from the hard drive. The hard drive has been replaced, indicating that the IDE interface of the motherboard is normal. The hard drive works fine on other machines. So far, it seems that every part is normal, but assembled together is not normal. After careful observation, it was found that the mainframe power supply was 200 watts. After replacing the 230 watt power supply, the Asustek motherboard started normally.
To confirm, replace the VXPro motherboard and find that there is still a fault. Another 200-watt power supply also broke down. Explain that the cause is indeed a problem with the power supply and the motherboard. Summary: first of all, the reason for the failure of this example is that the power of the old 200W power supply is too low and the MMXCPU needs more current. In addition, the VXPro motherboard does not support multi-functional Pentium very well. As a result, it comes to mind that when upgrading a computer, it is necessary to comprehensively consider the interrelationship of various components and comprehensively design the upgrade plan. In addition to giving the computer a Pentium "core", it is also necessary to prevent the phenomenon of a pony pulling a cart.
