16 Site Preparations
• In a dry, clean, well-ventilated and temperature-controlled room, away from heat sources such as hot
air vents or direct sunlight.
• Away from sources of severe electromagnetic noise.
• Positioned in a rack or cabinet, or on a desktop with adequate space in the front, rear, and sides of the
unit for proper ventilation, and access.
Cabinet placement
The S4810 should be installed only in indoor cabinets designed for use in a controlled environment as
described in the Site Selection heading. The S4810 should not be installed in outside plant cabinets.
The cabinet must meet the following criteria:
• Minimum cabinet size and airflow are according to the EIA standard.
• Minimum of 5 inches (12.7 cm) between the intake and exhaust vents and the cabinet wall.
Rack mounting
When you prepare your equipment rack, ensure that the rack is earth ground. The equipment rack must be
grounded to the same ground point used by the power service in your area. The ground path must be
permanent.
Grounding
The S4810 is for use in a Common Bond Network. You must connect grounding cables as described in
Chapter 3, Install the S4810 .
Fans and airflow
The S4810 system fans support with 2 air flow options. Be sure to order the fans suitable to support your
site’s proper ventilation. Use a single type of fan in your system. Do not mix Reverse and Normal airflows
in a single chassis.
• Normal is airflow from I/O panel to power supply
• Reversed is airflow from power supply to I/O panel
For proper ventilation, position the S4810 chassis in an equipment rack (or cabinet) with a minimum of
five inches (12.7 cm) of clearance around exhaust vents. When two S4810 systems are installed near each
other, position the two chassis at least 5 inches (12.7 cm) apart to permit proper airflow. The acceptable
ambient temperature ranges are listed in
