Power Requirements
The most important installation considerations are for power requirements. The basic power
requirements for the HP 3000 and HP 9000 Enterprise Servers are listed in Table 2-2. (Additional
power specifications are contained in Appendix B of this manual.) Also, refer to Section 3 of the
Computer Products Site Preparation Resource Guide. Your Hewlett-Packard Sales Representative and
CE can assist you in determining peripheral power requirements.
NOTE
Some systems require single-phase power. Single-phase power may be
obtained by making power connections in one of the following ways:
• Line-to-neutral: 200-240 Volts (One hot (phase) wire and a neutral).
• Line-to-line: 200-240 Volts. Connect across two phase (hot) wires.
