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.
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 TBD Watts of continuous power
per feed pair. Connection with a DC source should only be performed
by trained service personnel. If the DC power supply is installed in the
unit and the unit is not located in a Restricted Access Location, then
the DC source must be supplied from the secondary of a Listed
regulated power supply located within the same rack as the
equipment.
If DC power supplies are installed:
Main 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). The circuit breaker
of a centralized DC power system may be used as a disconnect
device when easily accessible.
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.
