Power Dissipation

Table 4-15 “Typical Superdome Configurations” and Table 4-16 “Typical hp 9000 Superdome Configurations” show the power requirements by configuration (i.e. number of cell boards, amount of memory per cell, and number of I/O chassis) for the Superdome and the hp 9000 Superdome, respectively.

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 may be used to assess average utility cost of cooling and electrical power. These tables also show 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, 220-volt phase-to-phase, 230-volt phase-to-phase, 240-volt phase-to-phase.

^[3]An input power source supplied from a three-pole plus PE, four-wire system may be wired as either:

200VAC phase-to-phase, plus a PE ground. The three phase input voltage to the equipment is connected phase-to-phase. The neutral terminal in the PDCA is not connected.
208VAC phase-to-phase, plus a PE ground. The three phase input voltage to the equipment is connected phase-to-phase. The neutral terminal in the PDCA is not connected.

208VAC phase-to-neutral, with a neutral return, plus a PE ground. Three phase input voltage to the equipment is connected phase-to-neutral. The neutral wire is connected to the PDCA neutral terminal.
220VAC phase-to-neutral, plus a PE ground. The three phase input voltage to the equipment is connected phase-to-neutral. The neutral wire is connected to the PDCA neutral terminal.
230VAC phase-to-neutral, plus a PE ground. The three phase input voltage to the equipment is connected phase-to-neutral. The neutral wire is connected to the PDCA neutral terminal.
240VAC phase-to-neutral, plus a PE ground. The three phase input voltage to the equipment is connected phase-to-neutral. The neutral wire is connected to the PDCA neutral terminal.

415VAC phase-to-neutral, plus a PE ground. The three phase input voltage to the equipment is connected phase-to-neutral. The neutral wire is connected to the PDCA neutral terminal.




	WARNING! Do not connect a 380 to 415VAC supply to a four-wire PDCA. This is a safety hazard and will result in damage to the product. Line-to-line or phase-to-phase voltage measured at 380 to 415VAC must always be connected using a 5-wire PDCA.

Acoustic Noise Specification

The acoustic noise specifications are as follows:

8.2 bel (sound power level)
65.1 dBA (sound pressure level at operator position)

The above levels are appropriate for dedicated computer room environments, not office environments.

Care should be taken to understand the acoustic noise specifications relative to operator positions within the computer room or when adding Superdome or hp 9000 Superdome systems to computer rooms with existing noise sources.

Air Flow

Superdome or hp 9000 Superdome systems require the cabinet air intake temperature to be between 20^ο C and 30^ο C at 2400 CFM. Any cooling system layouts described in Chapter 2 can be adapted to cool the system.

Figure 4-2 “Airflow Diagram” illustrates the location of the inlet and outlet airducts on a single cabinet.
