NonStop NS2400 Series Planning Guide

F Power Configurations for NonStop NS2400 Series
Systems in G2 Racks
This appendix describes power distribution and AC power inputs for NonStop NS2400 series
systems in G2 Racks.
For power configurations of systems shipped in Intelligent racks starting with the J06.14 RVU, see
“Power Distribution for NonStop NS2400 Series Systems In Intelligent Racks” (page 52).
Power Distribution for NonStop NS2400 Series Systems in G2 Racks
This subsection describes the power distribution units (PDUs), “AC Power Feeds” (page 60), and
PDU Strapping Configurations (page 66) for NonStop NS2400 series systems in G2 racks before
J06.14.
Depending on your NonStop NS2400 power configuration, your system uses one of these PDU
types:
• “PDUs for NonStop NS2400 Series System Single-Phase Power Configurations in G2 Racks”
(page 171)
• “PDUs for NonStop NS2400 Series System Three-Phase Power Configurations in G2 Racks”
(page 172)
PDUs for NonStop NS2400 Series System Single-Phase Power Configurations in G2
Racks
There are two implementations of single-phase PDUs:
• “Monitored Single-Phase PDUs” (page 171)
• “Modular Single-Phase PDUs (North America and Japan Only)” (page 172)
Monitored Single-Phase PDUs
Two single-phase power distribution units (PDUs) provide redundant power outlets for the components
mounted in the modular cabinet. The PDUs are oriented inward, facing the components within the
rack. Each PDU is 60 inches long and has 39 AC receptacles, three circuit breakers, and an AC
power cord. The PDU is oriented with the AC power cord exiting the modular cabinet at either the
top or bottom rear corners of the cabinet, depending on the sites power feed needs.
For information about specific input and output characteristics for factory-installed monitored PDUs,
see “North America and Japan: 200 to 240V AC, Monitored Single-Phase PDU Power” (page 183)
and “International: 200 to 240V AC, Monitored Single-Phase PDU Power” (page 183).
Each single-phase PDU in a modular cabinet has:
• 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
• 3 circuit-breakers
These single-phase PDU options are available to receive power from the site AC power source:
• 200V to 240V AC, single-phase for North America and Japan
• 200V to 240V AC, single-phase for International
Each PDU distributes site single-phase power to single-phase 200 to 240 V AC outlets for connecting
the power cords from the components mounted in the modular cabinet.
Figure 14 (page 61) shows the power feed cables on PDUs with AC feed at the bottom of the
cabinet and the AC power outlets along the PDU. These power outlets face in toward the cabinet.
