Bulk Power for Models 590 and 595
BPD(电源分布器)
BPC(电源控制器)
BPR(电源调节器)
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。
Each system will have 2 Bulk Power Assemblies (BPA) a front and a rear.
Front components will have odd numbers for their Px. Rear components will have even numbers for their Px. The bulk power components have a Unit type of 9458.100
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，
Bulk Power Distributor Bulk Power Assembly
Bulk Power Distributors (BPD) are the top most components in the BPA. The system can have from 1 to 3 components. The first to be installed will be Px-C3, filling upward. The front and rear BPA's will have the same number of BPD's
Each BPD will have 10 connection points as shown. The components that plug into these 10 connectors will change depending on which BPD you are using.
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D shell连接
T7只用于BPF(bulk power fan) T8用于MDA1 T9用于MDA2 T10用于MDA3 T11用于MDA4 T12用于DCA00 T30用于DCA01
Bulk Power Controller
The Bulk Power Controller (BPC) is the central communications component of the BPA. Each BPA will have just 1 controller.
The connections on the BPC are:
T1 through T4 are RJ45 style for its hub T5 and T6 are D shell connectors
T7 is a connection always for Bulk Power Fan T8 goes to Motor Drive Assembly (MDA) 1
T9 goes to MDA 2 T10 goes to MDA 3 T11 goes to MDA 4 T12 goes to DCA 00 T13 goes to DCA 01
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。 Bulk Power Regulator
A Bulk Power Regulator (BPR) will come with each BPA. The BPA can have up to 3 BPRs. Px-E1 will be the first BPR installed, filling downward.
Each BPR has one connection point in the middle for a possible connection to an Internal Battery Feature (IBF). Systems do not need to have IBFs.
