Site selection
Install Dell EMC equipment in restricted access areas.
A restricted access area is one where service personnel can only gain access using a special tool, lock, key, or other means of security. The
authority responsible for the location controls access to the restricted area.
Ensure that the area where you install switch meets the following safety requirements:
• Near an adequate power source. Connect the switch to the appropriate branch circuit protection according to your local electrical
codes.
• S4128F-ON, S4148F-ON, S4148FE-ON, S4128T-ON, S4148T-ON: Environmental—switch location—continuous temperature range is
from 5° to 40°C (50° to 104°F).
• S4148U-ON: Environmental—switch location—continuous temperature range is from 5° to 45°C (50° to 113°F).
• Operating humidity is from 5 to 85 percent noncondensing, continuous.
• In a dry, clean, well-ventilated, and temperature-controlled room, away from heat sources such as hot cooling vents or direct sunlight.
• Away from sources of severe electromagnetic noise.
• Inside the restricted access area, position in a rack or cabinet, or on a desktop with adequate space in the front, back, and sides for
proper ventilation and access.
• Install the switch in Information Technology Rooms in accordance with Article 645 of the National Electrical Code and NFPA 75.
