Electrical Specifications

The following specifications are based on HP Environmental Class C2. Class C2 is a controlled computer room environment where products are subject only to controlled temperature and humidity extremes. Throughout this chapter each specification is defined as thoroughly as possible to ensure that all data is considered to ensure a successful site preparation and system installation.

Grounding

The site building shall provide a safety ground/protective earth for each AC service entrance to all cabinets.

This equipment is CLASS 1 and requires full implementation of the grounding scheme to all equipment connections. Failure to attach Protective Earth results in loss of regulatory compliance and creates a possible safety hazard.

Circuit Breaker

Each cabinet using a three-phase, four-wire input requires dedicated circuit breaker to support the Marked Electrical current of 44A per phase. The facility electrician and local service codes will determine proper circuit breaker selection.

Each cabinet using a three-phase five-wire input requires a dedicated circuit breaker to support the Marked Electrical current of 24A per phase. The facility electrician and local service codes will determine proper circuit breaker selection.




	NOTE: When using the minimum sized breaker, always choose circuit breakers with the maximum allowed trip delay to avoid nuisance tripping.

Power Options

Table 4-6 “Available Power Options” describes the available power options. It may be unusual to list Options 6 and 7 and not 1 and 2. The options listed are consistent with previous options for earlier Superdome systems.

Table 4-6 Available Power Options

Option	Source Type	Source Voltage (nominal)	PDCA Required	Input Current Per Phase 200-240 VAC ^[1]	Power Receptacle Required
6	3-phase	Voltage range 200-240 VAC, phase-to-phase, 50 Hz / 60 Hz	four-wire	44A Maximum per phase	Connector and plug provided with a 2.5-meter power cable. Electrician must hard-wire receptacle to 60A site power.
7	3-phase	Voltage range 200-240 VAC, phase-to-neutral, 50 Hz / 60 Hz	five-wire	24A Maximum per phase	Connector and plug provided with a 2.5-meter power cable. Electrician must hard-wire receptacle to 32A site power.
^[1]A dedicated branch circuit is required for each PDCA installed.

Table 4-7 Option 6 and 7 Specifics

PDCA Part Number	Attached Power Cord	Attached Plug	Receptacle Required
A5201-69023 (Option 6)	OLFLEX 190 (PN 600804) is a 2.5 meter multi conductor, 600 volt, 90 degree C, UL and CSA approved, oil resistant flexible cable. (8 AWG 60 A capacity)	Mennekes ME 460P9 (60 A capacity)	Mennekes ME 460R9 (60 A capacity)
A5201-69024 (Option 7)	H07RN-F (OLFLEX PN 1600130) is a 2.5 meter heavy duty neoprene jacketed harmonized European flexible cable. (4 mm² 32A capacity)	Mennekes ME 532P6-14 (32A capacity)	Mennekes ME 532R6-1500 (32 A capacity)




	NOTE: A qualified electrician must wire the PDCA receptacle to site power using copper wire and in compliance with all local codes.

Each branch circuit used within a complex must be connected together to form a common ground.

When only one PDCA is to be installed in a system cabinet, it must be installed as PDCA0. Refer to Figure 4-1 “PDCA Locations” for PDCA0 location.




	NOTE: When wiring a PDCA, phase rotation is unimportant. When using two PDCAs, however, the rotation must be consistent for both.

Figure 4-1 PDCA Locations

System Power Requirements

Table 4-8 “Power Requirements (without Support Management Station)” and Table 4-9 “Component Power Requirements (without Support Management Station)” list the AC power requirements for a Superdome and hp 9000 Superdome systems. These tables provide information to help determine the amount of AC power needed for your computer room.

I/O Expansion Cabinet Power Requirements

The I/O expansion cabinet requires a single phase 200-240VAC input. Table 4-10 “I/O Expansion Cabinet Power Requirements (without Support Management Station)” lists the AC power requirements for the I/O expansion cabinet.




	NOTE: The IOX accommodates two AC inputs for redundancy
