If you install several HP NetServers on one circuit, however, precautions are
necessary. For instance, 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 capability, they may
trip and thus prevent the servers from powering up.
When preparing your site for installation, allow for the additional inrush current.
Consider the following before installing the server in your environment:
In North America, a 20-amp-minimum circuit is to be used with one
NEMA AB1 class 14B breaker for each 16-amp Power Distribution Unit
that is to be connected to an HP NetServer LXr 8500.
In Europe:
For a single LXr 8500 unit in a rack, use a 16-amp-minimum circuit
with one IEC MCB C-type breaker for each 16-amp Power Distribution
Unit.
For multiple LXr 8500 units in a rack, use a 16-amp-minimum circuit
with one IEC MCB D-type breaker for each 16-amp Power
Distribution Unit.
NOTE
Some local codes do not allow a 16-amp device to be
connected to a 16-amp service. Consult a qualified electrician
or local regulatory authority before beginning electrical site
preparation.

Unterminated Power Cords Require Licensed Electrician
In some cases in the 230/240V environment, the Uninterruptible Power Supply
(UPS) is shipped with a power cord that is unterminated. The reason is that the
current demand of a fully loaded rack may exceed the demand for the normal
circuit in some countries. Therefore, you should have a qualified electrician or
electrical engineer analyze the current demand for each branch circuit used by
rack mounted equipment. Proper wiring and cord termination are part of the same
process.
