The exact power requirements for the ATCA-9305 circuit board depend upon the specific
configuration of the board, including the CPU frequency and amount of memory installed on
the board. Please contact Artesyn Technical Support at 1-888-412-7832 if you have specific
questions regarding the board’s power requirements.

Environmental Considerations

As with any printed circuit board, be sure that air flow to the board is adequate. Chassis
constraints and other factors greatly affect the air flow rate. The environmental requirements
are as follows:

Table 2-3 Environmental Requirements

Requirement

Non-Operating

Temperature

+5 ºC (+41 °F) to +40 ºC (+104 °F)
(normal operation) according to NEBS
Standard GR-63-CORE

(exceptional operation) according to
NEBS Standard GR-63-CORE

-40 ºC (-40 °F) to +70 ºC (+158 °F)
(may be further limited by installed
accessories)

Airflow

The blade is designed to operate in a
chassis that provides 35 CFM across the
blade for the stated temperature range.
