双LED亮起。当CI872
模块以冗余配置运行。模块
双LED是否亮起？是否为主要[激活]
模块处于冗余配置。
注：即使备份CI872模块运行时出现错误或
冗余配置失败，双LED仍亮起
冗余配置的主CI872模块。
当出现以下任一情况时，双LED熄灭：黄色双LED熄灭：
满足以下条件：
•CI872以单一配置运行。
•CI872在冗余配置中运行，但它作为
备份模块。
所有LED均关闭可能原因1：CI872在
硬件树（在控件生成器中）与
CEX总线上的CI872位置。
纠正措施1：检查并纠正
硬件树中的CI872模块符合
CEX总线上的位置，反之亦然。
可能原因2：CI872模块热插入，并且
配置不会下载到控制器。
纠正措施2：确保模块已配置
在硬件树中（在控件生成器中）
位置，并将配置下载到
控制器。
可能原因3：CI872刚刚热插拔，它处于
配置过程。
纠正措施3：为模块初始化留出时间 8520-4APA1 85204APA1 壳处理器模块控制数据输入输出 A-B

g in the MOD5 communication interface, type - CI872.
Table 44. MOD5 Communication Interface, Type CI872 - Indications and Fault Finding
Indication Possible Causes, and Corrective Actions (for faults)
Both R(un) and F(ault)
LED's are OFF
Possible Cause 1: The CI872 module is connected to the
controller and the configuration is not downloaded to the
controller for that position.
Corrective Action 1: Ensure that the CI872 module is
configured in the Hardware Tree (in the Control Builder) for
that position, and that the configuration is downloaded to
controller.
Possible Cause 2: The CI872 module is just powered up or
it is being configured and downloaded.
Corrective Action 2: Allow time for the module to initialize.
Corrective Action 3: If the indication persists after
performing the corrective actions 1 and 2, then one of the
following corrective actions is recommended:
• Remove and insert the CI872 module to the CEX-Bus
and allow time for it to initialize.
• If the CEX-Bus already contains other communication
modules and all the LED's on those modules are OFF,
or if this CI872 is the only module on the CEX-Bus,
then check the CEX-Bus fuse inside the PM85x/PM86x
Processor Unit.
Corrective Action 4: If the indication still persists after
performing the corrective actions 1 to 3, replace the CI872
module.
MOD5 Interface - CI872 Section 5 Maintenance
240 3BSE036351-600 A
F(ault) LED is ON Possible Cause 1: The CI872 module is in the process of
upgrading the firmware (if the upgrade is in progress).
Corrective Action 1: Wait for the firmware to be upgraded.
Possible Cause 2: Fault in the CI872 module.
Corrective Action 2: Hot remove and hot insert the CI872
module.
Corrective Action 3: If the indication persists after
performing the corrective actions 1 and 2, then replace the
CI872 module.
R(un) LED is ON The green R(un) LED indicates that CI872 is operational.
Rx/Tx1, Rx/Tx2, and
Rx/Tx3 LEDs are flashing
There is one LED corresponding to each port on the CI872
module. When the LED corresponding to a port flashes, it
indicates that communication is happening on that particular
port.
Rx/Tx1, Rx/Tx2, Rx/Tx3
LED is OFF
Possible Cause 1: The fiber optic cable is not connected or
it is not connected properly to the port.
Corrective action 1: Do any of the following:
• Check the corresponding optical cable connections,
that is, the connections for reversed transmitter and
receiver optical cables for that particular port, and the
connections on the DOW MOD5 controller.
• Check the Network Controller Board (NCB) on the
MOD5 Controller connected to that particular port.
Possible Cause 2: The configuration is not downloaded
from the Hardware Tree (in the Control Builder) to the
controller.
Corrective Action 2: Ensure that the module is configured
in the Hardware Tree for the correct position and the
configuration is downloaded to controller.

DUAL LED is ON The yellow DUAL LED is illuminated when the CI872
module is run in redundant configuration. The module that
has the DUAL LED illuminated is the primary [active]
module in a redundant configuration.
Note: Even if the backup CI872 module runs with errors or
fails in redundant configuration, the DUAL LED is still ON in
primary CI872 module in redundant configuration.
DUAL LED is OFF The yellow DUAL LED is OFF when any of the following
conditions are met:
• CI872 is run in single configuration.
• CI872 is run in redundant configuration, but it acts as a
backup module.
All LED's are OFF Possible Cause 1: Difference in the CI872 position in the
Hardware Tree (in the Control Builder) as compared to the
CI872 position on the CEX-Bus.
Corrective Action 1: Check and correct the position of
CI872 module in the Hardware Tree in accordance with the
position on CEX-Bus, or vice-versa.
Possible Cause 2: The CI872 module is hot inserted and
the configuration is not downloaded to the controller.
Corrective Action 2: Ensure that the module is configured
in the Hardware Tree (in the Control Builder) for that
position, and that the configuration is downloaded to
controller.
Possible Cause 3: The CI872 is just hot inserted and it is in
the process of configuration.
Corrective Action 3: Allow time for the module to initialize | 8520-4APA1 85204APA1 壳处理器模块控制数据输入输出 A-B | | | |
