Heat Dissipation
Heat Dissipation
A significant amount of the electric energy that an equipment shelf consumes converts
into heat. Power draw and heat release from a shelf are dependent on the type of power
supplies and the type and the number of modules installed. To ensure the safety,
performance, and reliability of the system, excessive heat that modules generate must
dissipate into the surrounding air. Ventilation accelerates dissipation.
Your configuration might require an air conditioning system to cool the equipment to
acceptable operating temperatures. The capacity of the air conditioning system must be
large enough to sufficiently dissipate the heat that all equipment in the area generates. If
the temperature of the intake air flow is too high, an overtemperature condition occurs.
To estimate the heat flow volume that your cooling system must dissipate, calculate the
quantity of heat produced by each shelf when it consumes its required power.
CAUTION
Elevated Operating Ambient Temperature!
If installed in a cabinet or multi-rack assembly, the operating ambient
temperature of the rack environment may be greater than room
temperature. Be careful to install the equipment in an environment that is
compatible with the maximum ambient temperature (Tma) specified by
ADVA Optical Networking.
WARNING
To prevent the system from overheating, do not operate it in an area that
exceeds the maximum recommended ambient temperature of 104°F
(40°C).
