CHAPTER 3: PREPARING THE SITE
The EMS100G-32 is suitable for installation as part of a common bond network (CBN).
You can install the switch in:
Network telecommunications facilities
Data centers
Other locations where the National Electric Code (NEC) applies
NOTE: Install the EMS100G-32 switch into a rack or cabinet before installing any optional components.
3.1 SITE SELECTION
Install this equipment in restricted access areas.
A restricted access area is one in which service personnel can only gain access using a special tool, lock, key or other means of
security. Also, access is controlled by the authority responsible for the location.
Ensure that the area where you install your EMS100G-32 switch meets the following safety requirements:
Near an adequate power source. Connect the switch to the appropriate branch circuit protection as defined in your codes.
Environmental temperature range i from 32 to 113° F (0 to 45° C).
The switch operating ambient temperature range is from 50 to 95° F (10 to 35° F).
Operating humidity is from 5 to 85 percent noncondensing.
Storage humidity is from 5 to 95 percent noncondensing.
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 for proper ventilation and access.
3.2 CABINET PLACEMENT
Install the EMS100G-32 only in indoor cabinets designed for use in a controlled environment.
Do not install the S3048–ON in outside cabinets. For cabinet placement requirements, see Site Selection.
The cabinet must meet minimum size requirements. Airflow must be in accordance with the Electronic Industries Alliance (EIA)
standard. Ensure that there is a minimum of 5 inches (12.7 cm) between the intake and exhaust vents and the cabinet wall.
3.3 RACKMOUNTING
When you prepare your equipment rack, ensure that the rack is grounded.
Ground the equipment rack to the same ground point the power service in your area uses. The ground path must be permanent.

Black Box recommends you ground your switch. Use the EMS100G-32 in a common bond network (CBN).
Connect the grounding cables as described in Install the Switch.
