Site preparations
The S4112-ON Series (S4112F-ON and S4112T-ON) switch is suitable for installation as part
of a common bond network (CBN).
You can install the switch in:
• Network telecommunication facilities
• Data centers
• Other locations where the National Electric Code (NEC) applies
For more information about the S4112-ON Series switch specications, see Specications.
NOTE: Install the switch into a rack or cabinet before installing any optional
components.

• Storing components
Site selection
Install your 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 your 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.

Site preparations 7

• Environmental—switch location—continuous temperature range is from 5° to 40°C
(50° to 104°F).
• Operating humidity is from 5 to 85 percent non-condensing, 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.
• Positioned 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.
For more information about switch storage and environmental temperatures, see
Specications.
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.
For more information, see Ground cable.
8Site preparations

Fans and airow
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 congurations:
• AC PSU with PSU fan and system fans normal airow
• AC PSU with PSU fan and system fans reverse airow
• DC PSU with PSU fan and system fans normal airow
• DC PSU with PSU fan and system fans reverse airow
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 o the fans.
Power
To connect the switch to the applicable power source, use the appropriate power cable. An
AC power cable is included with the switch.
When installing AC or DC switches, follow the requirements of the National Electrical Code
ANSI/NFPA 70, where applicable.
The switch is powered-up when the power cable is connected between the switch and the
power source.
CAUTION: Always disconnect the power cable before you service the power supply
slots. The switch has multiple power cords. Before servicing, ensure all power cords
are disconnected.
CAUTION: On the AC switch, use the power supply cable as the main disconnect
device. Ensure that the socket-outlet is located/installed near the equipment and is
easily accessible.
NOTE: Module power is software controlled. You do not see module LEDs when the
switch powers up in ONIE.
Site preparations 9

Storing components
If you do not install your S4112-ON Series switch and components immediately, properly
store the switch and all optional components following these guidelines:
• Storage location temperature must remain constant. The storage range is from -40° to
65°C (-40° to 149°F).
• Store on a dry surface or oor, away from direct sunlight, heat, and air conditioning
ducts.
• Store in a dust-free environment.
NOTE: ESD damage can occur when components are mishandled. Always wear an
ESD-preventive wrist or heel ground strap when handling the switch and its
accessories. After you remove the original packaging, place the S4112-ON Series
switch and its components on an anti-static surface.
