Safety Guidelines
Grounding the rack installation: To avoid the potential for an electrical
shock hazard, you must include a third wire safety grounding 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 grounding 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. 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. If more than one server is installed in the
rack, the power source for each server must be from a separate branch
circuit. The overall current rating of a server configured with three
power supplies is under 12 amperes.
CAUTION
Temperature: The operating temperature of the server, when installed in an
equipment rack, must not go below 5 °C (41 °F) or rise above 35 °C (95 °F).
Extreme fluctuations in temperature can cause a variety of problems in your
server.
Ventilation: The equipment rack must provide sufficient airflow to the
front of the server to maintain proper cooling. It must also include
ventilation sufficient to exhaust a maximum of 3,150 Btu's per hour for the
server. The rack selected and the ventilation provided must be suitable to
the environment in which the server will be used.
