Heat Considerations

This section describes the heat output of the Sun Datacenter Switch 3456 and its
potential safety hazard for personnel. This section also describes keeping an open
area at the exhaust side, and considerations for other systems and equipment in the
area.

Air Temperature

The calculated approximate air temperature output of the Sun Datacenter Switch
3456 is 36°F (20°C) hotter than the air going in. While this output temperature is not
hot enough to burn, this temperature is sufficient to dehydrate and render useless
any cooling device in the vicinity.
