Connecting the HP NetServer to AC Power

When you connect the NetServer to an AC power source, the server temporarily
draws additional current. This occurs even when the system is in standby mode.
This "inrush current" is much greater than the server's normal operating needs.
Generally, your external AC power source can handle the inrush current.
If you install several HP NetServers on one circuit, precautions are necessary. If
there is a power failure and power is then restored, all the servers immediately
begin to draw inrush current at the same time. If the circuit breakers on the
incoming power line have insufficient capacity, they may trip and thus prevent the
servers from powering up.
