11. Heat radiation data
When in use, all Cisco gateway units and radio transceivers generateheat
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.
