可能原因1：CI869模块已连接
到控制器，但配置不是
下载到该位置的控制器。
纠正措施1：确保CI869模块
在硬件树（控件中）中配置
构建器），并且配置为
下载到控制器。
可能原因2：CI869模块只是
通电或正在配置，并且
下载。
纠正措施2：允许模块有时间
初始化。
纠正措施3：如果指示在
执行纠正措施1和2，然后
建议采取以下纠正措施：
•取下CI869模块并将其插入
CEX总线，并为其初始化留出时间。
•如果CI869是上的模块
CEX总线，或者如果CEX总线已经包含
其他通信模块和所有LED
在这些模块关闭时
建议采取以下纠正措施：
-从PM8xx启动复位信号（INIT）
处理器单元。
-检查PM8xx内的CEX总线保险丝
处理器单元
纠正措施4：如果指示仍然存在
执行纠正措施1至3后，更换
CI869模块。

F（故障）指示灯亮起可能原因1：CI869模块位于
固件升级过程（如果升级为
正在进行中）。
纠正措施1：等待固件
升级。
可能原因2：CI869模块故障。
纠正措施2：热移除和热插入
CI869模块。
纠正措施3：如果指示在
执行纠正措施1和2，然后
更换CI869模块。
接收LED亮起（无
闪光）
CI869模块正在运行，并且正在接收

当CI869模块以冗余配置运行时，双LED亮起。
当CI869模块以冗余配置运行时，Prim（ary）LED亮起，
并且它作为主模块起作用。
注：即使备份CI869模块运行
冗余配置中的错误或故障，Prim
中的主CI869模块中的LED仍亮起

Possible Cause 1: The CI869 module is connected
to the controller, but the configuration is not
downloaded to the controller for that position.
Corrective Action 1: Ensure that the CI869 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 CI869 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 CI869 module to the
CEX-Bus and allow time for it to initialize.
• If this CI869 is the only module on the
CEX-Bus, or if the CEX-Bus already contains
other communication modules and all the LED's
on those modules are OFF, then one of the
following corrective actions is recommended:
- Initiate a reset signal (INIT) from the PM8xx
processor unit.
- Check the CEX-Bus fuse inside the PM8xx
processor Unit
Corrective Action 4: If the indication still persists
after performing the corrective actions 1 to 3, replace
the CI869 module.

236 3BSE036351-600 A
F(ault) LED is ON Possible Cause 1: The CI869 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 CI869 module.
Corrective Action 2: Hot remove and hot insert the
CI869 module.
Corrective Action 3: If the indication persists after
performing the corrective actions 1 and 2, then
replace the CI869 module.
Rx LED is ON (without
flashing)
The CI869 module is operational, and it is receiving
and transmitting data.
Rx LED is flashing with
less frequency
Possible Cause 1: The twisted wire pair (TWP) is
not connected or it is not connected properly to the
4-pin contact.
Corrective action 1: Check the TWP connections.
Rx LED is flashing with
50% more frequency than
when the TWP is not
connected
Possible Cause 1: The configuration is not
downloaded from the Hardware Tree (in the Control
Builder) to the controller.
Corrective Action 1: Ensure that the CI869 module
is configured in the Hardware Tree for the correct
position and the configuration is downloaded to
controller.
Rx LED is flashing with
75% more frequency than
when the TWP is not
connected
Possible Cause: At least one of the configured
DSPs does not respond when polled.
Corrective Action: Configure the DSPs correctly.

Dual LED is ON The CI869 module is run in redundant configuration.
Prim(ary) LED is ON The CI869 module is run in redundant configuration,
and it functions as the primary module.
Note: Even if the backup CI869 module runs with
errors or fails in redundant configuration, the Prim
LED is still ON in the primary CI869 module in
redundant configuration | AGILENT 安捷伦 5517B 激光头 376uW分频 2.11MHz | | | |
