Appendix G. Cabling Information
This appendix provides information about the location of the pSeries 655 cables.
Note: The cables tied along the cable raceway may settle during shipment and might be tight when
reconnecting to the BPA. The cable ties may need to be loosened and cable slack pulled back up
in order to be reconnected.
Power Cabling
The following illustrations and table provide detailed information about power connectors and cables.
Bulk Power Subsystem Connector Locations
The following illustration shows front (A) and rear (B) connector locations on the BPD and BPC. The
illustration also shows the order in which the connectors are to be plugged. To determine cable locations,
connections, and part numbers, use this illustration, the illustration shown in "Rack Configuration Drawer
Assignments," and the table in "Power Cable Part Numbers" on page 156.
BPD 1 A or B
BPC A or B
EPO UPS
P00
The designation shown in the illustration for BPD and BDC A or B indicates the A side (front) or B side
(rear) of the BPD or BPC.
Power cables from the BPC and BPD connect to the processor subsystems DCAs or to the I/O
subsystems. See "Power Cable Part Numbers" on page 156 for cable connections.
Rack Configuration Drawer Assignments
The following illustration shows the rack configurations, placement code sequence, and assigned BPC and
BPD connections. Use this illustration and the following table to determine the part numbers for power
cables and the required connections.
