Appendix E Superdome Configurations

Table E-1 “Typical Superdome Configurations” shows Superdome power requirements by configuration (i.e. number of cell boards, amount of memory per cell, and number of I/O chassis). This requirement applies to 32-way-capable systems with PA8600 or PA8700 processors.

There are two columns of power numbers (Watts). The Power Breaker column shows the power used to size the wall breaker at the installation site. The Typical Power column shows typical power. Typical power numbers are for PA8600 systems and may be used to assess average utility cost of cooling and electrical power. Expect these typical numbers to be about 18% less for PA8700 systems. Table E-1 “Typical Superdome Configurations” also shows the recommended breaker sizes for 4-wire and 5-wire sources.

^[1]These numbers are valid only for the specific configurations shown. Any upgrades may require a change to the breaker size. A 5-wire source utilizes a 4 pole breaker and a 4-wire source utilizes a 3 pole breaker. The PE (Protective Earth) ground wire is not switched. ^[2]An input power source supplied from a 3-pole plus protective earth (PE), 4-wire system will always be wired as 240 volts phase-to-phase, no neutral or common, plus a PE ground. Three phase input voltage (240VAC) to the equipment is connected phase-to-phase. Examples of 4 wire: 200-volt phase-to-phase, 208-volt phase-to-phase, 240-volt phase-to-phase ^[3]An input power source supplied from a 4-pole +PE, 5 wire system may be wired as either: 208VAC phase-to-phase voltage with a common, plus a PE ground. Three phase input voltage (208VAC) to the equipment is connected phase-to-phase. The common is not connected to the PDCA neutral terminal. 415VAC phase-to-phase voltage with a neutral return, plus a PE ground. Three phase input voltage (230-240VAC) to the equipment is connected phase-to-neutral. The neutral is connected to the PDCA neutral terminal. Examples of 5 wire: 208-volt phase-to-phase, 380-volt phase-to-phase, 415-volt phase-to-phase
