11. Heat radiation data
When in use, all Cisco gateway units and radio transceivers generate
heat
as a by-product of electrical activity.
Heat
radiated
by
a
Cisco
device
may
be
of
concern
in
confined
locations such as server rooms (where the cumulative heat generated by
a
collection
of
electrical
and
electronic
devices
may
cause
damage
to
sensitive
electronic
components)
and
outdoor
equipment
enclosures
(in
which electronic components may overheat if the enclosure is not properly
ventilated).
WARNING
The outer surfaces of some Cisco units may become hot
during
normal
operation.
Such
units
have
a
'Hot
Surfaces'
warning triangle on their outer enclosures.
During
normal
operation,
do
not
touch
or
handle
such
unit
enclosures without personal protective equipment.
The following table shows nominal heat-radiation figures for all Cisco
devices under idle conditions, and under full-load conditions.
All
heat-radiation
figures
are
given
in
British
Thermal
Units
(BTU)
per
hour.
