A. There is a fire hazard potential if a power outage occurs.B. The last system plugged into the UPS will not be provided any power.C. The UPS will draw more power from the circuit to compensate.D. The runtime of the UPS will be insufficient if a power outage occurs.
考题
在主从同步并联冗余UPS中，指定其中一台单机UPS为主UPS，其余的为从UPS。在正常情况下，有市电时，主UPS同步于市电，无市电时，同步于自己的内部晶振；所有“从UPS ”（可编号为1，2，3„）都同步于主UPS。如主UPS 故障，1号“从UPS ”自动变为主UPS。以此类推，2号、3号„等UPS也可为主UPS。
考题
在无主从同步并联冗余UPS中，不指定主UPS，任何一个单机UPS都可以为主UPS也可以为从UPS。一般按开机情况随机确定主UPS，例如哪一台先启动完毕，即为主UPS，此主UPS 故障时，由从UPS 替代原主UPS。
