2.3.4 Bulk power regulators (BPR)
The redundant BPRs interface to the bulk power assemblies to help ensure proper power is
supplied to the system components. Figure 2-22 on page 62 shows four BPR assemblies.
The BPRs are always installed in pairs in the front and rear bulk power assemblies to provide
redundancy. One to four BPRs are installed in each BPA. A BPR is capable of supplying 8 KW
of 350 VDC power. The number of bulk power regulators required is configuration dependent,
based on the number of processor MCMs and I/O drawers installed. Figure 2-22 on page 62
details the BPR assembly.
