Additional precautions for the equipment rack
Use only the rack mounting assemblies that have been designed and tested for the FT5000 server.
Other mountings may be unstable or unable to withstand the server weight when it is extended
from the normal position for maintenance.
WARNING
Mitsubishi Electric PC Division accepts no responsibility for any damage or injury resulting from
the improper installation of rack-mountable components into rack units.
Important points to note:
Anchor the equipment rack: The equipment rack must be anchored to an non-movable support to
prevent it from falling over should one or more servers be extended in front of it on their slide
assemblies. The anchors must be able to withstand a force of up to 113 kg. You must also consider
the weight of any other device installed in the rack.
Main AC power disconnect: You are responsible for installing an AC power disconnect for the
entire rack unit. This main disconnect must be readily accessible, and it must be labelled as
controlling power to the entire unit, not just to the server(s).
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 server power cords are
plugged into AC outlets that are part of the rack, then you must provide proper grounding for the
rack itself. If server power cords are plugged into wall AC outlets, the safety grounding conductor
in each power cord provides proper grounding only for the server. You must provide additional,
proper grounding for the rack and other devices installed in it.
Over-current protection: The server is designed for an AC line voltage source with up to 20
amperes of over-current 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 amps.
CAUTION
If the rack unit is provided with any power distribution control circuitry, ensure that the circuits
are not overloaded. It is also important that you do not overload the main AC outlet that provides
power to the rack.
Temperature: The operating temperature of the server, when installed in an equipment rack, must
not go below 5°C or rise above 35°C. Extreme fluctuations in temperature can cause a variety of
problems or permanent damage within 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 approximately
1200W of heat 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.
