Site preparations
The S4200-ON Series (S4248FB-ON and S4248FBL-ON) 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 S4200-ON Series specifications, see Specifications.
NOTE: Install the switch into a rack or cabinet before installing any optional components.
Topics:
•Site selection
•Cabinet placement
•Rack mounting
•Switch ground
•Fans and airflow
•Power
•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.
●Environmental—switch location—continuous temperature range is from 0°C to 45°C (32°F 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.
●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 Specifications.
Cabinet placement
Install the S4200-ON Series (S4248FB-ON and S4248FBL-ON) switch only in indoor cabinets designed for use in a controlled
environment.
Do not install the switch 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.

6 Site preparations

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 S4200-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 S4200-ON Series has SKUs
that support the following configurations:
●AC PSU with fan airflow from the I/O to the PSU—normal
●AC PSU with fan airflow from the PSU to the I/O—reverse
●DC fan unit with airflow from the I/O to the PSU—normal
●DC fan unit with fan airflow from the PSU to the I/O—reverse
Be sure to order the fans suitable to support your site’s ventilation. Use a single type of airflow fan in your switch. Do not mix
reverse and normal airflows in a single switch.
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.
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.
Storing components
If you do not install your S4200-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°C to 70°C (-40°F to 158°F).
●Store on a dry surface or floor, 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 S4200-ON Series
switch and its components on an anti-static surface.

Rack or cabinet installation
You may either place the switch on a rack shelf or mount the switch directly into a 19" wide, EIA-310- E-compliant rack.
Rack mounting includes four-post, two-post, round threaded holes, or square holes. The ReadyRails system is provided for 1U
front-rack and two-post installations.
The ReadyRails system includes two separately packaged rail assemblies. To begin installation, separate each rail assembly by
sliding the inside rail out of the outside rail.
WARNING: This guide is a condensed reference. Read the safety instructions in your Safety, Environmental, and
Regulatory information booklet before you begin.
NOTE: The illustrations in this section are not intended to represent a specific switch.
NOTE: Do not the use the mounted ReadyRails as a shelf or a workplace.
Rack mount safety considerations
●Rack loading—Overloading or uneven loading of racks may result in shelf or rack failure, possibly damaging the equipment
and causing personal injury. Stabilize racks in a permanent location before loading begins. Mount the components starting at
the bottom of the rack, then work to the top. Do not exceed your rack’s load rating.
●Power considerations—Connect only to the power source specified on the unit. When you install multiple electrical
components in a rack, ensure that the total component power ratings do not exceed the circuit capabilities. Overloaded
power sources and extension cords present fire and shock hazards.
●Elevated ambient temperature—If you install the switch in a closed rack assembly, the operating temperature of the rack
environment may be greater than the room ambient temperature. Use care not to exceed the 45°C maximum ambient
temperature of the switch.
●Reduced air flow—Do not compromise the amount of airflow required for safe operation of the equipment. Install the
equipment in the rack so that the equipment constantly has the correct amount of airflow surrounding it.
●Reliable earthing—Maintain reliable earthing of rack-mounted equipment. Pay particular attention to the supply connections
other than the direct connections to the branch circuit, for example: use of power strips.
●Do not mount the equipment with the fan panel facing in the downward position.
ReadyRails installation
To easily configure your rack for switch installation, use the ReadyRails rack mounting system provided.
You can install the ReadyRails system using the 1U tool-less square-hole method or one of three possible 1U threaded round-hole
methods. The tooled installation methods include two-post flush mount, two-post center mount, or four-post threaded mount.
To begin installation, separate each rail assembly by sliding the inside rail out of the outside rail.
NOTE: For more installation instructions, see the installation labels attached to the rail assembly.
