Site selection
Install Dell EMC equipment in restricted access areas.
A restricted access area is one in which 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 S4200-ON Series 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.
● Switch environmental temperature range is from 0° to 45°C (32° to 113°F).
● Relative humidity is from 5 to 90 percent noncondensing.
● In a dry, clean, well-ventilated and temperature-controlled room, away from heat sources such as hot air vents or direct
sunlight.
● Away from sources of severe electromagnetic noise.
● Inside the restricted access area, 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.
Site preparations 13
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.
Connect the grounding cables as described in S4200–ON Series Installation.
Fans and airflow
The S4200-ON Series (S4248FB-ON and S4248FBL-ON) switch fans support two airflow options: normal and reverse.
Fan combinations
Installation of the fans 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 or DC PSU with fan airflow from the I/O to the PSU—the red indicator is the normal airflow.
● AC or DC PSU with fan airflow from the PSU to the I/O—the blue indicator is the reverse airflow.
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 S4200-ON Series 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. When you install two S4200-ON Series switches near each other, to permit proper airflow, position
the two switches at least 5 inches (12.7 cm) apart. The fan speed varies based on internal temperature monitoring. The S4200ON Series never intentionally turns off the fans.
For more information, see Fans.
Power
Use the appropriate power cord with the S4200-ON Series (S4248FB-ON and S4248FBL-ON) when connecting the switch to
the power source. An AC power cord is included with each PSU.
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 cord is connected between the switch and the power source. For more information,
see Power Supplies.
CAUTION:
multiple power cords. Before servicing, ensure all power cords are disconnected.
CAUTION: Use the power supply cord as the main disconnect device on the AC switch. 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.
Always disconnect the power cable before you service the power supply slots. The switch has
Component storage
If you do not install your S4200-ON Series (S4248FB-ON and S4248FBL-ON) switch and components immediately, properly
store the switch and all optional components by following these guidelines:
● Storage location temperature must remain constant. The storage range is from -40°C to 70°C (-40°F to 158°F).
14
Site preparations
● Store on a dry surface or floor, away from direct sunlight, heat, and air conditioning ducts.
● Store in a dust-free environment.

To be NEBS compliant, orient your switch in the rack so that the air inlet is from the front aisle and the air exhaust is to the
back aisle.
Topics:
• Important information
• NEBS-compliant ground installation
Important information
WARNING: The SFP+, QSFP, QSFP28, console, Ethernet management, and universal serial bus (USB) ports are
suitable for connection to intrabuilding or unexposed wiring or cabling only. You MUST NOT metallically connect
the ports to interfaces that connect to the out side plant (OSP) or its wiring. Use these interfaces as
intrabuilding interfaces only (Type-2 or Type-4 ports as described in GR-1089-CORE, Issue 6) and they require
isolation from the exposed OSP cabling. Adding primary protectors is not sufficient protection to connect these
interfaces metallically to OSP wiring.

Safety, Environmental,
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 downward.
ReadyRails Installation
To easily configure your rack for installation of your S4200-ON Series (S4248FB-ON and S4248FBL-ON) switch, 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—2-post flush mount, 2-post center mount, or 4-post mount.
CAUTION:

Power supplies
The S4200-ON Series (S4248FB-ON and S4248FBL-ON) switch ships with two AC or DC power supplies.
The S4200-ON Series switch supports AC or DC power supplies with two air-flow directions, normal and reverse. Normal is from
the I/O to the PSU side. Reverse is from the PSU side to the I/O side. Two PSUs are required for full redundancy, but the
switch can operate with a single PSU.
The PSUs are field replaceable. When running with full redundancy—two power supplies installed and running, you can remove
and replace one PSU without disrupting traffic.
CAUTION: To prevent electrical shock, ensure that the S4200-ON Series switch is grounded properly. If you do
not ground your equipment correctly, excessive emissions may result. Use a qualified electrician to ensure that
the power cables meet your local electrical requirements.
NOTE: Connect the power supply to the appropriate branch circuit protection as defined by your local electrical codes and
verify that the remote power source complies with the switch input power specifications.
NOTE: If you use a single PSU, install a blank plate in the other PSU slot. Use power supply 2 (PSU2) as the blank plate
slot. To install the blank plate, use a #1 Philips screw driver.

Fans
The S4200-ON Series (S4248FB-ON and S4248FBL-ON) switch comes from the factory with two PSUs and five fan modules
installed in the switch. The fan modules and the power supplies, which have integrated fans, are hot-swappable.
In addition to the power supply modules, you can order and install fan modules separately.
The S4200-ON Series switch supports two airflow direction options—normal and reverse. All fans and PSUs MUST have the
same airflow direction. If you mix the airflow direction, to avoid heat damage to the switch components, you must correct the
mixed airflow direction.
● Airflow is from the I/O panel to the PSU—normal.
● Airflow is from the PSU to the I/O panel—reverse.
Environmental factors can decrease the amount of time required between fan replacements. Check the environmental factors
regularly. An increase in temperature and particulate matter in the air might affect performance—for example, new equipment

During the initial setup, the switch boots to ONIE Install. ONIE Install boots with ONIE Discovery to the console (ONIE:).
ONIE service discovery
ONIE attempts to locate the installer through several discovery methods, as shown. To download and run an installer, the ONIE
Service Discovery feature uses the first successful method found.
1. Search locally attached storage devices for one of the ONIE default installer filenames—for example, the filename is: onie
self update from the USB.
2. Query to the IPv4 and IPv6 link-local neighbors using HTTP for an installer.
3. Discover TFTP-based image from the DHCP server.
If none of the ONIE Service Discovery methods are successful, you can disable this using the onie-discovery-stop
command.
You can install an operating system manually from HTTP, FTP, or TFTP using the onie-nos-install <URL> command.
If you have a recovery USB plugged into your switch, remove it before installing the DIAG-OS using the onie-
NOTE:
nos-install command.
The ONIE Install environment uses DHCP to assign an IP address to the management interface—eth0. If that fails, it uses the
default IP address 192.168.3.10/255.255.255.0.

Waste Electrical and Electronic Equipment (WEEE) directive for recovery,
recycle, and reuse of IT and telecommunications products
Dell EMC switches are labeled in accordance with European Directive 2002/96/EC concerning waste electrical and electronic
equipment (WEEE). The Directive determines the framework for the return and recycling of used appliances as applicable
throughout the European Union. This label is applied to various products to indicate that the product is not to be thrown away,
but rather reclaimed upon end of life per this Directive.
Figure 27. The European WEEE symbol
In accordance with the European WEEE Directive, electrical and electronic equipment (EEE) is to be collected separately and to
be reused, recycled, or recovered at end of life. Users of EEE with the WEEE marking per Annex IV of the WEEE Directive, as
shown above, must not dispose of end of life EEE as unsorted municipal waste, but use the collection framework available to
customers for the return, recycling and recovery of WEEE. Customer participation is important to minimize any potential effects
of EEE on the environment and human health due to the potential presence of hazardous substances in EEE.
Dell EMC products, which fall within the scope of the WEEE, are labeled with the crossed-out wheelie-bin symbol, as shown
above, as required by WEEE.
For information on Dell EMC product recycling offerings, see the WEEE Recycling instructions on the Support page. For more
information, contact the Dell EMC Technical Assistance Center.
