and four on the right). If a single-phase UPS is used, the four extension bars on the left are connected
to the UPS instead of two modular PDUs.
For information about modular PDU input and output characteristics, see “North America and
Japan: 200 to 240V AC, Modular Single-Phase PDU Power” (page 192).
PDUs for NonStop NS2200 System Three-Phase Power Configurations in G2 Racks
Two power distribution units (PDUs) are installed to 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 site's power feed needs.
For information about specific PDU input and output characteristics for PDUs factory-installed in
modular cabinets, see “AC Input Power for Modular Cabinets in G2 Racks” (page 190).
Each three-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 three-phase PDU options are available to receive power from the site AC power source:
• 200V to 240V AC, three-phase delta for North America and Japan
• 380V to 415V AC, three-phase wye for International
Each PDU distributes site three-phase power to 39 single-phase 200 to 240V AC outlets for
connecting the power cords from the components mounted in the modular cabinet.
AC Power Feeds for NonStop NS2200 Systems in G2 Racks
Power can enter the NonStop NS2200 system from either the top or the bottom rear of the modular
cabinets, depending on how the cabinets are ordered from HP and how the AC power feeds are
routed at the site. NonStop NS2200 system 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.
Depending on your power configuration, your NonStop NS2200 system uses one of these
configurations:
AC Power Feeds Without UPS and ERM
• “Bottom AC Power Feed Without UPS and ERM (Single-Phase or Three-Phase)” (page 183)
• “Top AC Power Feed Without UPS and ERM (Single-Phase or Three-Phase)” (page 183)
AC Power Feeds With UPS and ERM, Single-Phase
• “Top AC Power Feed With UPS and ERM Installed, Single-Phase” (page 184)
• “Bottom AC Power Feed With UPS and ERM Installed, Single-Phase” (page 184)
AC Power Feeds With UPS, Single-Phase Modular PDUs
• “Top AC Power Feed With UPS and Single-Phase Modular PDUs” (page 185)
• “Bottom AC Power Feed With UPS and Single-Phase Modular PDUs” (page 186)
