冗余配置中的控制器重置
按照以下步骤执行冗余配置中的控制器重置：
1.执行备份CPU的控制器重置。系统将采用单CPU
状态
2.等待几秒钟，然后在主CPU上执行控制器重置。
自动切换到备份CPU
在冗余配置中，从主CPU到
备份CPU在以下情况下发生，前提是它们处于同步状态
状态（双LED点亮）：
•主CPU内存错误。
•主CPU中的其他硬件错误，导致CPU崩溃。
•控制网络上的严重通信错误，即两种情况都丢失
主CPU中的网络端口。
•模块总线上的严重通信错误（如果模块总线是
HW配置），即主CPU中的群集丢失。
请注意，ModuleBus上存在严重通信错误的备份CPU
将被拒绝（如果ModuleBus是硬件配置的一部分），并且
只要错误仍然存在，就永远不会达到同步状态。

n three seconds) until the Run LED begins to flash. A Controller Reset must be
performed if the system is in an undefined position and consequently unavailable to
the user.
Controller Reset in Redundant Configuration
Follow the steps below to perform a Controller Reset in redundant configuration:
1. Perform a Controller Reset of the backup CPU. The system will go single CPU
state.
2. Wait a few seconds and then perform a Controller Reset on the Primary CPU.
Automatic Switch-Over to Backup CPU
In a redundant configuration an automatic switch-over from the Primary CPU to the
Backup CPU occurs in the following situations, provided they are in synchronized
state (DUAL LED is lit):
• Memory error in the Primary CPU.
• Other HW-error in the Primary CPU, which causes CPU crash.
• Severe communication errors on the Control network, that is, loss of both
network ports in the Primary CPU.
• Severe communication errors on the ModuleBus (if ModuleBus is part of the
HW configuration) that is, loss of clusters in the Primary CPU.
Note that a Backup CPU with severe communication errors on the ModuleBus
will be rejected (if ModuleBus is part of the HW configuration) and
synchronized state will never be reached as long as error remains.

To affirm, following start-up, that the AC 800M Controller and all associated units
are operating correctly, see Table 22 on page 194.
Verification of Single CPU
Check the status of each LED indicator and compare it against the criteria listed in
the table. If the status is other than that listed, see Fault-Finding Procedures on page
