Server System SR1690WB Service Guide 93
Rack Mount Installation Guidelines
Anchor the equipment rack: The equipment rack must be anchored to an unmovable
support to prevent it from falling over when one or more servers are extended in front of
the rack on slides. You must also consider the weight of any other device installed in the
rack. A crush hazard exists should the rack tilt forward which could cause serious injury.
Temperature: The temperature, in which the server operates when installed in an
equipment rack, must not go below 5 °C (41 °F) or rise above 40 °C (104 °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. The rack must also include ventilation sufficient to exhaust a
maximum of 1023 BTUs (British Thermal Units) 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.
If AC power supplies are installed:
Mains AC power disconnection: 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 main
disconnect must be readily accessible, and it must be labeled as controlling power to the
entire rack, 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 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.
If DC power supplies are installed:
Connection with a DC (Direct Current) source should only be performed by trained
service personnel. The server with DC input is to be installed in a Restricted Access
Location in accordance with articles 110-16, 110-17, and 110-18 of the National Electric
Code, ANSI/NFPA 70. The DC source must be electrically isolated by double or
reinforced insulation from any hazardous AC source.
