HP cc3300 Carrier Grade Server 11
Quick Start Guide
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 a
server configured with two power supplies is less than 4 amperes.
If DC power supplies are 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 W of continuous power per feed pair.
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.
Overcurrent protection: Overcurrent protection circuit breakers must
be provided as part of each host equipment rack and must be installed
between the DC source and the server. The server is designed for a
DC line voltage power source with up to 10 amperes of overcurrent
protection per feed pair. If the DC power system for the equipment rack
is installed with more than 10 amperes of protection, you must provide
supplemental protection for the server. The overall current rating of a
server configured with two power supplies is less than 7 amperes.
