BPD（电源分布器）

BulkPowerforModels590and595

BPR（电源调节器）

BPC（电源控制器）

每个系统即（595/590）有两个BPA（大容量电力集成模块），一个在前面，一个在背面。

它们是互相冗余的。

分别有两条电源线路接入，

前机的组件部分使用的是奇数号Px，背面的使用的是隅数号Px。

BPD（大容量电力分布器）是BPA最上面的部件，可以有1到3个，第一个是Px-C3，

正面和背面的BPA通过有相同数量的BPD。

每个BPD有10个连接口，

BPC（大容量电力控制器）是BPA的核心通信部件，每个BPA只有一个控制器。

T1至T4是RJ45型的HUB

T5和T6是Dshell连接

T7只用于BPF（bulkpowerfan）

BPR（大电力调节器），一个BPA最多少3个，Px-E1是第一个，

每个BPR在中间位置有一个连接口，用于连接IBF（内部电池功能模块）。

系统不一定需要IBF。
