HP cc2300 Carrier Grade Server Quick Start Guide 11
Mains AC power disconnect: The AC power cord(s) is considered the
mains disconnect for the server and must be readily accessible when
installed. If the individual server power cord(s) will not be readily
accessible for disconnection then you are responsible for installing an
AC power disconnect for the entire rack unit. This mains disconnect
must be readily accessible, and it must be labeled as controlling power to
the entire rack, not just to the server(s). To remove all power, the
AC cord must be removed.
Grounding the rack installation: To avoid the potential for an electrical
shock hazard, you must include a third wire safety ground conductor
with the rack installation. If the server power cord is plugged into an
AC outlet that is part of the rack, then you must provide proper
grounding for the rack itself. If the server power cord is plugged into a
wall AC outlet, the safety ground conductor in the power cord provides
proper grounding only for the server. You must provide additional,
proper grounding for the rack and other devices installed in it.
Overcurrent protection: The server is designed for an AC line voltage
source with up to 20 amperes of overcurrent protection per cord feed. If
the power system for the equipment rack is installed on a branch circuit
with more than 20 amperes of protection, you must provide
supplemental protection for the server. The overall current rating of the
server is less than 4 amperes.
If a DC power supply is installed:
The DC source must be electrically isolated by double or reinforced
insulation from any hazardous AC or DC source. The DC source must
be capable of providing up to 300 mW of continuous power. Connection
with a DC source should only be performed by trained service
personnel.
Mains DC power disconnect: You are responsible for installing a
DC power disconnect for the entire rack unit. This mains disconnect
must be readily accessible, and it must be labeled as controlling power to
the entire unit, not just to the servers(s).
Grounding the rack installation: To avoid the potential for an electrical
shock hazard, you must include a third wire safety ground conductor
with the rack installation. The safety grounding conductor must be a
minimum 14AWG connected to the earth ground stud on the rear of the
server. The safety ground conductor should be connected to the chassis
stud with a two hole crimp terminal with a maximum width of 0.25 inch.
The nuts on the chassis studs should be installed with a 10 in/lbs torque.
The safety ground conductor provides proper grounding only for the
server. You must provide additional, proper grounding for the rack and
other devices installed in it.
