2.4.2 Environmental Considerations
As with any printed circuit board, make sure that the 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 2-22 Environmental Requirements
Requirement Operating Non-Operating
Temperature +5 ºC (+41 °F) to +40 ºC (+104 °F)
(normal operation) according to NEBS
Standard GR-63-CORE
-5 ºC (+23 °F) to +55 ºC (+131 °F)
(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 -

Standard GR-63-CORE +/- 0.5 ºC/min
Relative humidity 5% to 90% non-condensing according to
Artesyn Embedded Technologies-
