3BHE022455R1101耦合器,3BHE022455R1101控制卡输入/输出总线终端为便于更换故障RCM，应位于扩展总线末端，并使用专用终端电缆连接-目录号IC697CBL803（3英尺（0.9米））。可以在对扩展总线中断最小的情况下移除此电缆，KSD211B 3BHE022455R1101耦合器尤其是当系统中包含一个或多个扩展机架时。使用电缆IC600WDXXX（其中XXX为表3所示的英尺长度）
连接扩展机架CPU机架中的总线发送器模块（BTM）连接到扩展机架中的BRM。（适用于FIP单机架冗余系统以外的系统）。其他扩展机架通过BRM之间的菊花链布线添加，RCM始终最后连接。卸下模块D时，用拇指放在板盖的前部，手指放在板盖背面的塑料夹子上，牢牢抓住板盖的顶部和底部。KSD211B 3BHE022455R1101耦合器D用手指挤压盖背面的齿条夹，使其与齿条导轨分离
I/O Bus Termination
To allow for easy replacement of a faulty RCM, it should
be located at the end of the expansion bus and connected
using a special terminated cable - catalog number
IC697CBL803 (3 feet (0.9 meters). This cable can be
removed with minimal disruption of the expansion bus,
especially when one or more expansion racks are included
in the system.
Expansion Rack Attachment
Using cable IC600WDXXX (where XXX is length in feet
as shown in Table 3) a Bus Transmitter Module (BTM) in
the CPU rack connects to a BRM in an expansion rack.
(Appliocable if used in a system other than the FIP single
rack redundant system). Additional expansion racks are
added by daisy-chaining cabling between BRMs with the
RCM always connected last.
Removing a Module
D
Grasp the board firmly at the top and bottom of the
board cover with your thumbs on the front of the
cover and your fingers on the plastic clips on the back
of the cover.
D
Squeeze the rack clips on the back of the cover with
your fingers to disengage the clip from the rack rail
