2.3.3.1 主机架的报警指示
当下列情况下,主机架电源模件的报警接点被触发:
—系统的配置不能和控制程序的配置匹配。
—数字输出(DO)模件之一中出现了LOAD/FUSE错误。
—系统中某个地方的模件缺失。(没有那个状态指示灯会报警您关于这个问题)。
—主机架内有一个主处理器或I/O模件故障。
—扩展机架中某个在线I/O模件故障。
如果在某一扩展机架内的某I/O模件内有着一支路故障但还能继续正确地运行或者把控制传递给了热备,则主机架报警不会发动。
—主处理器探测到有一系统故障。在此情况下,两个报警触点都可能被发动而没有相应的模件故障。
—机架之间的I/O总线电缆安装不正确—例如支路A的电缆不小心地被连到了支路B上。
当下列情况下,主机架电源模件的至少一个上的报警触点被发动:
—电源模件故障。
—通向电源模件的供电电源消失。
—电源模件上有一个“电池电压低”或“温度过高”的报警。
警告!
不要在危险区使用报警接点
2.3.3.2 扩展机架的报警情况
扩展机架上的两个电源模件的报警接点在当I/O模件失效时发动。当发生下列情况时,扩展机架的至少一个电源模件的报警接点被激动:
—有一个电源模件故障
—引入电源模件的输入电源丢失
—电源模件有一温度过高的报警
