Rack mount safety considerations
• Elevated Ambient Temperature: If the equipment is installed in a closed rack
assembly, the operation temperature of the rack environment may be greater than
room ambient. Use care not to exceed the rated maximum ambient temperature of
the equipment.
• Reduced Air Flow: Installation of the equipment in a rack should be such that the
amount of airfl ow required for safe operation of the equipment is not compromised.
• Mechanical Loading: Mounting of the equipment in the rack should be such
that a hazardous condition is not achieved due to uneven mechanical loading.
• Circuit Overloading: Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of circuits might
have on overcurrent protection and supply wiring. Consider equipment name-
plate ratings for maximum current.
• Reliable Earthing: Reliable earthing of rackmounted equipment should be
maintained. Pay particular attention to supply connections other than direct
connections to the branch circuit (for example, use of power strips).
