Heat Dissipation
A. General Information
AT&T utilizes both the nominal (normal operating) and maximum heat values
(use Watts vs. BTU) for equipment when designing equipment space
infrastructures. The nominal heat value is the primary driver of cooling
requirements. Heat values are documented on the ESP form and, where
required, on the ATIS charts.
ATIS heat reporting charts provide five (5) points of heat. This information
provides a more detailed understanding of the overall equipment cooling
demand.
• Values entered into ESP and ATIS forms may be measured and/or
calculated values.
The configuration of equipment deployed in OSP/CELL-SITE cabinets must be
approved by OSP/CELL-SITE staff prior to approval for use.
