AC Input Power for Modular Cabinets
This subsection provides information about AC input power for modular cabinets and covers
these topics:
• “North America and Japan: 208 V AC PDU Power”
• “International: 400 V AC PDU Power”
• “Branch Circuits and Circuit Breakers”
• “Enclosure AC Input” (page 45)
• “Enclosure Power Loads” (page 46)
Power can enter the NonStop BladeSystem from either the top or the bottom rear of the modular
cabinets, depending on how the cabinets are ordered from HP and the AC power feeds are routed
at the site. NonStop BladeSystem cabinets can be ordered with the AC power cords for the PDU
installed either:
• Top: Power and I/O cables are routed from above the modular cabinet.
• Bottom: Power and I/O cables are routed from below the modular cabinet
For information on the modular cabinets, refer to “Modular Cabinets” (page 37). For information
on the PDUs, refer to “Power Distribution Units (PDUs)” (page 42).
North America and Japan: 208 V AC PDU Power
The cabinet includes two power distribution units (PDU). The PDU power characteristics are:
• 208 V AC, 3-phase delta, 24A RMS, 4-wire
• 50/60Hz
• NEMA L15-30 input plug
• 6.5 feet (2 m) attached power cord
PDU input characteristics
• 3 circuit-breaker-protected 13.86A load segments
• 36 AC receptacles per PDU (12 per segment) - IEC 320
C13 10A receptacle type
• 3 AC receptacles per PDU (1 per segment) - IEC 320
C19 16A receptacle type
PDU output characteristics
International: 400 V AC PDU Power
