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 Site selection.

The cabinet must meet minimum size requirements. Airow 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.
