Section 3 - Hardware Installation
• Ensure that proper airflow is provided to components in the rack.
• Do not step on or stand on any component when servicing other components in a rack.
CAUTION: Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground
conductor. Contact the appropriate electrical inspection authority or an electrician if uncertain that suitable grounding
is available.
CAUTION: The system chassis must be positively grounded to the rack cabinet frame. Do not attempt to connect power
to the system until grounding cables are connected. Completed power and safety ground wiring must be inspected
by a qualified electrical inspector. An energy hazard will exist if the safety ground cable is omitted or disconnected.
Please be aware of following safety instructions when installing rack-mountable products:
A. Elevated Operating Ambient Temperature - If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room temperature. Therefore, consideration should be given to
installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the
manufacturer.
B. Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required for safe
operation of the equipment is not compromised.
C. Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not achieved
due to uneven mechanical loading.
D. Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and the effect
that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
E. Reliable Grounding - Reliable grounding of rack-mounted equipment should be maintained. Particular attention should be
given to supply connections other than direct connections to the branch circuit (e.g. use of power strips).
