CHAPTER 3: PREPARING THE SITE
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 EMS10G12 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 continuous temperature range from 50 to 104° F (5 to 40° C).
Operating humidity is from 5 to 85 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.
Inside the restricted access area, positioned in a rack or cabinet, or on a desktop with adequate space in the front, rear, and sides for
proper ventilation and access.
Install the switch in information technology rooms in accordance with Article 645 of the National Electric Code and NFPA 75.
For more information about switch storage and environmental temperatures, see the Specifications chapter in this manual.

3.2 CABINET PLACEMENT
Install the EMS10G12 only in indoor cabinets designed for use in a controlled environment.
Do not install the EMS10G12 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.
3.4 SWITCH GROUND
Black Box recommends you ground your switch. Use the EMS10G12 in a common bond network (CBN).
Connect the grounding cables as described in Install the Switch.
NOTE: For this AC-powered switch, although the third conductor of the AC power cord provides a ground path, we recommend
grounding your switch with a dedicated ground wire.
