Chapter 1 Cautions and Considerations 3
Chassis Activity Dimensions
TABLE 1-1
provides Sun Datacenter Switch 3456 chassis dimensions, and the
minimum dimensions needed for unpacking, moving, and the final location.
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.
