Introducing the SA7x Enclosure
1.1 SA7x Enclosure Overview

The fan assembly circulates cooling air throughout the frame of the SA7x

enclosure. The air is drawn in through holes in the front panel on the enclosure

and is exhausted through holes in the rear panel.
The SA7x enclosure meets the following environmental and safety standards:
• DEC Standard 102 for environment
• DEC Standard 103 for electromagnetic emissions
• DEC Standard 104 for computer room noise level
• DEC Standard 119 for product safety
• National and international regulatory agency requirements, including FCC,

UL, IEC, CSA, and VDE

Your Digital sales representative can answer specific questions related to the

various environmental and safety standards.
