Review the documentation that comes with your rack enclosure for
safety and cabling considerations. When installing your server in a
rack the following considerations should be made:
• The server should be installed in a maximum 35 degree C
environment.
• To ensure proper air flow, it is recommended that the air vents
not be blocked, usually 15 cm (6 inches) of air space is sufficient.
• To ensure stability, precautions should be taken to prevent
uneven loading of the rack. Loading of the rack should begin at
the bottom.
• When multiple devices are installed in a rack, precautions
should be taken to prevent overloading of power outlets.
• The server should always be connected to a properly grounded
outlet.
