1、IBM小型机Power595结构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) 每个系统即有两个BPA，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 component
2、s will have even numbers for their Px. The bulk power components have a Unit type of 9458.100 BPD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
3、 1 to 3 components. The first to be installed will be Px-C3, filling upward. The front and rear BPAs will have the same number of BPDs 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B
4、PA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
5、 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，一个BPA最多少3个，Px-E1是第一个， 每个BPR在中
6、间位置有一个连接口，用于连接IBF。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 (I
7、BF). Systems do not need to have IBFs. 595/590 CEC PU BOOK(CPU,内存,IO通信卡等) System VPD FSP0 FSP1 DCA(给PU BOOK,供电) Node 0 P2 in front DCA 00 = E10 DCA 01 = E11 DCA 02 = E12 Node 1 P3 in front DCA 10 = E7 DCA 11 = E8 DCA 12 = E9 Node 2 P4 in front DCA 20 = E4 DCA 21 = E5 DCA 22 = E6 Node 3 P5 in front D

9、housing with single blower rear left A6-A1 is a housing with single blower rear right P1 is the backplane in the middle of the enclosure. The nodes, DCAs, FSPs, osilators and the system VPD plug into this backplane. P6 is in the front, it is a light strip used to identify components associated with
10、the front of the system. P7 is in the rear, it is the light strip used to identify components associated with the rear of the system. On the rear of the system you have connections for: System VPD - located on the system backplane above and between the osilators, location code is C5 FSP 0 is the rig

12、mporary line disturbances. The IBFs are connected to the BPA but physically reside in an I/O drawer slot Each book in the CEC cage and each I/O drawers have n+1 DCAs to convert the bulk voltage to logic level voltage Concurrent maintenance of all Power FRUs Power Cage Each A frame in the configurati
13、on has a single redundant BPA which contains (per side) 1 AC line input cord 1-3 BPRs to convert AC to 350v DC 1 BPC which controls the BPA and distributes 350v DC to some of the logic 1-3 BPDs distributes 350v DC to some of the logic 1 BPF for air-cooling the BPA CEC Cage Power 3 DCAs per node book
14、 provide N+1 logic DC levels The DCA trio located on the CEC cage back, behind the node they support Node books are isolated into their own power planes which allows the system to poweron/off individual nodes within the CEC cage Logic board mounted DCAs Each installed node has 3 DCAs on CEC board ba

16、or BPR pair (non-redundant mode) can have one battery installed to keep power up in case of temporary line disturbance CEC A Frame Note: Power components are in Red Full-drawer cabling For an I/O drawer, the following connections are required. _ One cable from the P1 RIO-2 Riser card J0 to CEC I/O c
17、ard Px-Cx-T1. _ One cable from the P2 RIO-2 Riser card J1 to CEC I/O card Px-Cx-T2. These cables provides a data and communication path between the memory cards and the I/O drawers (Figure 2-11). _ A cable is also added between P1 RIO-2 Riser card J1 and P2 RIO-2 Riser card J0 in each drawer. This c
18、able ensures that each side of the drawer (P1 and P2) can be accessed by the CEC I/O (RIO-2 adapter) card, even if one of the cables are damaged. Each half of the I/O drawer can communicate with the CEC I/O card for its own uses or on behalf of the other side of the drawer. There is an identifier (I
19、D) in the cable plugs which gives the length of the cable to the Inter-Integrated Circuit (I2C) bus and the service processor. The cable ID is the function that verifies the length of the RIO-2 cable. There are different RIO-2 cables, because we use CEC frame, powered 24 inch A frame, and unpowered
20、24 inch Z frame for the I/O drawer. With the cable ID we calculate the length and the link speed for the RIO-2 cable. Half-drawer cabling Although I/O drawers will not be built in half-drawer configurations, they can be cabled to, and addressed by the CEC, in half drawer increments (Figure 2-12). Bo
21、th STI connectors on one CEC I/O card Px-Cx-T1 and Px-Cx-T2 will be cabled to both ports on P1 RIO-2 Riser card. Both STI connectors on a different CEC I/O card Px-Cx-T1 and Px-Cx-T2 (possibly on a different processor book) will be cabled to both ports on P2 RIO-2 Riser card. However, to simplify th
22、e management of the server we strongly recommend that I/O loops be configured as described in the IBM Sserver Information Center, and to only follow a different order when absolutely necessary. In any case, it becomes extremely important for the management of the system to keep an up-to-date cabling
23、 documentation of your systems, because it may be different from the cabling diagrams of the installation guides. The I/O drawers provide internal storage and I/O connectivity to the system. Figure 2-13 shows the rear view of an I/O drawer, with the PCI-X slots and riser cards that connect to the RIO-2 ports in the I/O books.
