Site Preparation
Required tools:
• #2 Phillips screwdriver
• flathead screwdriver
• anti-static bags, mats, and packaging
• ESD wrist strap
Chassis Location Requirements
Allow at least 3 in. (7.6 cm) clearance on the sides of the chassis for proper airflow and at
least 2.5 in. (6.4 cm) in front for cable management. See Figure 12 .
Warning: Failure to comply with the location requirements outlined in
Installation Locations on page 58
and Chassis Location Requirements on page 59
will impede proper airflow and will result in thermal failure.
Note: The Fan module provides 120 CFM of airflow through the 7705 SAR-8 (8 fans at
14.8 CFM/fan).
Observe the following requirements when installing the system.
• Ensure that the chassis is located in an area that can provide an average inlet air temperature (bulk air temperature averaged over 1 year) no greater than 104°F
(40°C) under full system power loading combined with worst-case environmental deployment conditions per GR-63.
• Ensure that the 7705 SAR-8 system intake is not located immediately adjacent to the exhaust of another chassis such that preheated air above 40°C long term or 55°C short term (per GR-63) is drawn into the system.
• Ensure that the 7705 SAR-8 system intake is not located immediately adjacent to the intake of another chassis such that 7705 SAR-8 airflow is restricted in any way.
• Ensure that the inlet and exhaust of the chassis is free of obstructions from cabling,
mounting hardware, or other electronic equipment in the areas shown in Figure 12 .
