sufficient number of helpers. Remove obstacles such as cables and other objects from
the floor.
• To prevent the rack from tipping, and to minimize personnel injury in the event of a
seismic occurrence, securely anchor the rack to a wall or other rigid structure that is
attached to both the floor and to the ceiling of the room.
B.2.4
Electrical guidelines
• These enclosures work with single-phase power systems having an earth ground
connection. To reduce the risk of electric shock, do not plug an enclosure into any other
type of power system. Contact your facilities manager or a qualified electrician if you
are not sure what type of power is supplied to your building.
• Enclosures are shipped with a grounding-type (three-wire) power cord. To reduce the
risk of electric shock, always plug the cord into a grounded power outlet.
• Do not use household extension cords with the enclosures. Not all power cords have the
same current ratings. Household extension cords do not have overload protection and
are not meant for use with computer systems.
B.2.5
Ventilation requirements
Refer to
B.5 "Environmental Requirements"
for detailed environmental
requirements.
• Do not block or cover ventilation openings at the front and rear of an enclosure. Never
place an enclosure near a radiator or heating vent. Failure to follow these guidelines can
cause overheating and affect the reliability and warranty of your enclosure.
• Leave a minimum of 6 inches (15.2 cm) at the front and back of each enclosure to ensure
adequate airflow for cooling. No cooling clearance is required on the sides, top, or
bottom of enclosures.
• Leave enough space in front and in back of an enclosure to allow access to enclosure
components for servicing. Removing a component requires a clearance of at least 15
inches (38.1 cm) in front of and behind the enclosure.
B.2.6
Cabling requirements
• Keep power and interface cables clear of foot traffic. Route cables in locations that
protect the cables from damage.
• Route interface cables away from motors and other sources of magnetic or radio
frequency interference.
• Stay within the cable length limitations.
