CAUTION!
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 it on slide assemblies. The equipment rack must be installed
according to the manufacturer's instructions. 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 labeled 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.
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 1840 Btu's per hour for a fully loaded SX220 server.
It is important to note that this is the maximum, and a minimum or typical system
could be much less. You may want to calculate the BTU/hr more accurately for your
configuration. An extra 500 BTU/hr over many systems would translate into a large
error calculating air conditioning capacity.
