RCU黄色LED黄色LED具有两种功能。
正常:表示存在RCU服务数据

PMs中的RCU。
故障:表示上部/下部有问题
交换机,RCU数据链路(光纤)断开
或者RCU控制链路断开。
当没有故障时,LED将显示
如果RCU服务数据是否流动。如果有
LED上方的一个或多个故障条件
将改变行为并眨眼数次
以指示故障。这是在三秒钟内完成的
间隔,每个故障有一个间隔。这
当任何故障仍然存在时,它仍然存在。
-1闪烁=上/下开关处于相同位置
-2次闪烁=RCU数据链路关闭(光链路)

C1 or C2 LED OFF despite
accessing CEX-units
CEX-Bus units using no interrupt, no action is
needed.
RCU Yellow LED The yellow LED serves two functions.
Normal: indicates that there is RCU service data
traffic flowing in both directions between the
RCUs in the PMs.
Fault: indicate problem with UPPER/LOWER
switches, that RCU data link (fibre optical) is down
or that RCU control link is down.
When there is no fault condition the LED will show
if RCU service data is flowing or not. If there is
one or more of the fault conditions above the LED
will change behavior and blink a number of times
to indicate the fault. This is done in three seconds
intervals with one interval for each fault. This
persists while any fault remains.
- 1 blink = up/lo switches in same position
- 2 blinks = RCU data link down (opto link)
- 3 blinks = RCU control link down

Neither R(un) nor F(ault) LEDs
are ON
The SM810/SM811/SM812 board is in the
process of being restarted or configured. Allow
time for this to finalize.
If the condition persists, and no other unit LED on
the CEX-Bus is lit:
• Check the Log File
• Check the CEX-Bus fuse inside the CPU unit.
• Initiate a reset signal (INIT) from the CPU
unit.
• Replace the SM810/SM811/SM812 unit.
F(ault) LED is ON Unit error. R
