Electrical requirements
Line voltage
Line voltage (AC) at the wall power outlet is a function of the local power
utility and your building power distribution network. Voltages outside of
the operating range of the disk array can cause intermittent system errors or
a complete system shutdown. If required, an HP representative and your
electrician can determine the current line voltage and make
recommendations. See Appendix A for specific AC line voltage
requirements.
Avoid the use of a line voltage conditioner.
Make sure that a power distribution unit (if used) provides the correct
voltage to support your entire system.
Branch circuit breakers
See Appendix A for specific branch circuit requirements for your power
situation.
Single-phase branch circuit breakers
The power cords supplied are specified for connection to a single-phase,
20-amp circuit.
Frequency
Usually, AC line frequency is determined by your local power providers. In
some cases, electrical power is supplied by generators. Shifts in AC line
frequency can cause system errors. An HP representative can monitor the
frequency of the input AC line power and make recommendations, if
necessary. The disk array requires that the line frequency be within 0.5 Hz
of the rated line frequency (50 Hz or 60 Hz). See Appendix A for more
information.
