要在冗余CPU配置中交换RCU链路电缆，请执行
以下步骤：
1.关闭备用CPU的电源。（主CPU上电必须：
仍然打开。）
2.断开RCU链路电缆与备份CPU的连接。
3.断开RCU链路电缆与主CPU的连接。
4.将新的RCU链路电缆连接到主CPU，注意上部
电缆方向。
不要在5.0之前的版本中在线更换RCU链路电缆
对在线更换的支持也取决于硬件产品版本
水平。请参阅发行说明（参见已发行的用户手册和发行版
详见第31页的注释）。
请勿在5.0之前的版本中在线更换光缆。支持
在线更换也取决于硬件产品版本级别。请
请参阅发行说明（请参阅上的已发行用户手册和发行说明
第31页）。
新的电缆端必须连接到中的冗余CPU（）
与更换的电缆相同。因此，电缆端部的上部标记
必须位于与交换前相同的CPU上。

ame control network, might cause control network problems due to the MAC
and IP address handling. See MAC and IP Address Handling in Redundant
Configuration on page 53. Such reuse should not be fulfilled unless both the
replaced module and the module previously acting together with it in redundant
configuration are known to be restored from the previous mutual address swap.
It is recommended to set up an IP-config session and use the “Restore factory
settings” option subsequently followed by reassignment of the IP address or
assignment of a new IP address.

To exchange a RCU link cable in a redundant CPU configuration, perform the
following steps:
1. Switch OFF the Power for the backup CPU. (Power on the primary CPU must
still be On.)
2. Disconnect the RCU link cable from the backup CPU.
3. Disconnect the RCU link cable from the primary CPU.
4. Attach the new RCU link cable to the primary CPU, note the UPPER
orientation on the cable.
Do not replace the RCU link cable online in a previous version than 5.0. The
support for online replacement also depends on hardware Product Revision
levels. Please refer to the Release Notes (see Released User Manuals and Release
Notes on page 31) for detailed information.
Do not replace the optical cable online in a previous version than 5.0. The support
for online replacement also depends on hardware Product Revision levels. Please
refer to the Release Notes (see Released User Manuals and Release Notes on
page 31) for detailed information.
The new cable-ends must be connected to the redundant CPUs (exactly) in the
same way as the replaced cable was. Thus, the UPPER mark on the cable-end
must be located to the same CPU as before the exchange.

To exchange a TK857V0003 cable in a redundant CPU configuration, perform the
following steps:
1. Switch OFF or disconnect Power for the backup CPU.
2. Switch OFF or disconnect Power for the BC820, if external power is
connected.
3. Disconnect the cable from the backup CPU.
4. Disconnect the cable from the BC820.
5. Attach the new cable to the backup CPU
6. Attach the other end of the cable to the BC820.
7. Switch ON or reconnect the Power to the backup CPU and the BC820. 803456-4T 可分布式现场电源模块PlC电源 Reliance
