Connecting the HP NetServer to AC Power

When you connect the HP 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.
When preparing your site for installation, allow for the additional inrush current.
Follow these circuit breaker recommendations before installing the server at your
site:
In North America, use a 20-amp-minimum circuit with one NEMA AB1
class 14B breaker for each 16-amp Power Distribution Unit (PDU).
In Europe:
For a single NetServer in a rack, use a 15-amp-minimum circuit with
one IEC MCB C-type breaker for each 16-amp PDU.
For multiple NetServers in a rack, use a 15-amp-minimum circuit with
one IEC MCB D-type breaker for each 16-amp PDU.
