Typically used for fires only since instantaneous removal of power from all system components can result in damage or alteration to electrical and mechanical parts, disk, or tape file. (Normally, a system “power off" results in sequenced removal of power from components effected by timing circuits.) 在大多数的设备面板或控制台上都有一专用控制开关,只要按下这一开关,计算机系统的 全部电源立即断开。该开关通常只在火灾情况下使用,因为瞬时切断全系统电源易导致电气 和机械部件、磁盘或磁带文档的破坏(通常系统断电通过定时电路实现有序地去掉各部件的 电源)。 |
