随着电子计算机技术的迅猛发展,局域网及其应用越来越普及,但对局域网的供电系统和电源配置尚未引起足够的重视。据有关部门调查表明,局域网最容易发生的问题往往是由于电源停电以及电源异常造成的各种故障。经专业机构测试统计,平均一台计算机每月要遭受到120多次各种电源问题所带来的影响。因此,局域网如何合理正确配置和选择不间断电源装置(UPS)已成为局域网正常运行的关键因素之一。 With the rapid development of computer technology, LANs and their applications are becoming more and more popular. However, the power supply system and power supply for LANs have not been given enough attention. According to relevant departments survey shows that the most prone to LAN problems are often due to power blackouts and power failures caused by a variety of failures. The professional organizations test statistics, on average, a computer every month to suffer more than 120 times the impact of various power problems. Therefore, LAN how reasonable and correct configuration and selection of uninterruptible power supply (UPS) has become one of the key factors in the normal operation of the LAN.
