1.5.2 Bulk Power and Control Assembly
Each Bulk Power and Control Assembly (BPCA) is a modular unit that includes the following
features:
Bulk Power and Control Enclosure (BPCE)
Contains two 125A 3-phase AC couplers, six BPR bays, one BPCH and one BPD bay.
Bulk Power Regulators (BPR), each rated at 27 KW@-360 VDC
One to six BPRs are populated in the BPCE depending on CEC drawers and storage
enclosures in frame, and the type of power cord redundancy that is wanted.
Bulk Power Control and Communications Hub (BPCH)
This unit provides rack-level control, storage enclosures, and water conditioning units
(WCUs), and concentration of the communications interfaces to the unit level controllers
that are in each server node, storage enclosure, and WCU.
Bulk Power Distribution (BPD)
This unit distributes 360 VDC to server nodes and disk enclosures.
