GE 12A0-0103-A3 PLC模块卡件
1.产 品 详 情 资 料：
R（un）和F（ault）指示灯均不亮。GE 12A0-0103-A3装置正在配置中。等待配置完成。如果这种情况持续存在，并且CEX总线上没有其他单元指示灯亮起：•检查PM8xx处理器单元内的CEX总线保险丝。•从PM8xx处理器单元启动复位信号（INIT）。•更换GE 12A0-0103-A3装置。故障指示灯亮起GE 12A0-0103-A3装置正在重新启动过程中。等待重新启动操作完成。如果情况依然存在，请更换单元。RxTx1/RxTx2（1）LED熄灭，各以太网信道无接收或发送活动。RxTx1/RxTx2（1）LED闪烁各个以太网通道的接收或传输活动正常。双LED亮起GE 12A0-0103-A3模块在冗余配置中运行。Prim（ary）LED亮起。GE 12A0-0103-A3模块在冗余配置中运行，它起到主模块的作用。注意：即使备份GE 12A0-0103-A3模块在冗余配置中出现错误或故障，冗余配置中主GE 12A0-0103-A3的Prim LED仍亮起。（1） 可以通过禁用CH2通道来关闭LED。GE 12A0-0103-A3支持热插拔。
Neither R(un) nor F(ault) LEDs are ON The GE 12A0-0103-A3 unit is in the process of being configured. Wait until the configuration is complete. If the condition persist, and no other unit LED on the CEX-Bus is ON: • Check the CEX-Bus fuse inside the PM8xx processor unit. • Initiate a reset signal (INIT) from the PM8xx processor unit. • Replace the GE 12A0-0103-A3 unit. F(ault) LED is ON The GE 12A0-0103-A3 unit is in the process of being restarted. Wait until the restart operation is complete. Replace unit if the condition persists. RxTx1/RxTx2(1) LED is OFF No Receive or transmit activity for respective Ethernet channels. RxTx1/RxTx2(1) LED is flashing Receive or transmit activity for respective Ethernet channels is normal.Dual LED is ON The GE 12A0-0103-A3 module is run in redundant configuration. Prim(ary) LED is ON The GE 12A0-0103-A3 module is run in redundant configuration, and it functions as the primary module. Note: Even if the backup GE 12A0-0103-A3 module runs with errors or fails in redundant configuration, the Prim LED is still ON in the primary GE 12A0-0103-A3 module in redundant configuration. (1) LED can be switched off by disabling CH2 channel. GE 12A0-0103-A3 supports hot swap.
