6、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 RegulatorA 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 (

17、connections are required._ One cable from the P1 RIO-2 Riser card J0 to CEC I/O card 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 memorycards and the I/O drawers (Figure 2-11)._ A cable is also added bet

18、ween P1 RIO-2 Riser card J1 and P2 RIO-2 Risercard J0 in each drawer.This cable ensures that each side of the drawer (P1 and P2) can be accessedby 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 itsown uses

19、 or on behalf of the other side of the drawer.There is an identifier (ID) in the cable plugs which gives the length of the cable tothe 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 aredifferent RIO-2 cable

20、s, because we use CEC frame, powered 24 inch A frame,and unpowered 24 inch Z frame for the I/O drawer. With the cable ID we calculatethe length and the link speed for the RIO-2 cable.Half-drawer cablingAlthough I/O drawers will not be built in half-drawer configurations, they can becabled to, and addressed by the CEC, in half drawer increments (Figure 2-12).Both STI connectors on one CEC I/O card Px-Cx-T1 and Px-Cx-T2 will be cabledto 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 bo
