Cabinet placement
Install the S4112-ON Series switch only in indoor cabinets designed for use in a controlled
environment.
Do not install the S4112-ON Series switch in outside cabinets. For cabinet placement
requirements, see

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.
Rack mounting
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.
Switch ground
Dell EMC recommends grounding your switch. Use the S4112-ON Series switch in a CBN.

Fans and airflow
Fan installation is done as part of the factory install based on stock keeping unit (SKU)
type. The S4112-ON Series switch has SKUs that support the following configurations:
•
AC PSU with PSU fan and system fans normal airflow
•
AC PSU with PSU fan and system fans reverse airflow
•
DC PSU with PSU fan and system fans normal airflow
•
DC PSU with PSU fan and system fans reverse airflow
For proper ventilation, position the switch in an equipment rack or cabinet with a minimum
of 5 inches (12.7 cm) of clearance around the exhaust vents. The fan speed varies based
on internal temperature monitoring. The switch never intentionally turns off the fans.
