Site selection
Install Dell EMC 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 S4112–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.
• Environmental, or switch location, temperature range is from (from 5° to 40°C (50 to 104°F).
• Operating humidity is from 5 to 85 percent non-condensing.
• 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.
• 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 Specications.

18
Page 19
5 inches (12.7 cm) apart. The fan speed varies based on internal temperature monitoring. The S4112–ON Series never intentionally turns o
the fans.
For more information, see Fans.
Power
To connect the switch to the applicable power source, use the appropriate power cable. An AC power cable is included with each PSU.
When installing AC or DC switch, 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.
After you connect the AC power cable to the switch, attach the metal wire clip. For more information, see Power supplies.
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.
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

NOTE: The illustrations in this section are not intended to represent a specic switch.
: This guide is a condensed reference. Read the safety instructions in your
Safety, Environmental, and Regulatory
NOTE: Do not the use the mounted rails 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 specied 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 re 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 (113°F) maximum ambient temperature of the
switch.

• Reduced air ow—Do not compromise the amount of airow required for safe operation of the equipment. Install the equipment in the
rack so that the equipment constantly has the correct amount of airow 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.
Half RU front-rack installation
The dual-tray mounting rails ship with the dual tray, not with the switch. You must supply eight rack-mount screws for this four-post

Before you install an OS
After powering on the S4112-ON Series (S4112F-ON and S4112T-ON) switch, it goes through a power-on self-test (POST).
POST runs every time the switch is initialized and checks the hardware components to determine if the switch is fully operational before
booting. After POST, the switch uses the Grub bootloader.
To select an entry, use the up and down arrow keys. Press Enter to select an operating software (OS) or enter e to edit the commands
before booting. Enter c for a command line. The selected entry runs automatically in the operating system.

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 rst successful method found.
1 Search locally attached storage devices for one of the ONIE default installer lenames—for example, the lename is: onie self
update from the USB.
2 Search locally attached storage devices for one of the ONIE default installer lenames—for example, USB.
3 Query to the IPv4 and IPv6 link-local neighbors using HTTP for an installer.
4 Discover TFTP-based image from the DHCP server.
Examples of ONIE ifconfig eth0 commands
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.
NOTE
: If you have a recovery USB plugged into your switch, remove it before installing the DIAG-OS using the onie-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

Product recycling and disposal
You must recycle or discard this switch according to applicable local and national regulations. Dell EMC encourages owners of information
technology (IT) equipment to responsibly recycle their equipment when it is no longer needed. Dell EMC oers a variety of product return
programs and services in several countries to assist equipment owners in recycling their IT products.
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 37. 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 eects 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 oerings, see the WEEE Recycling instructions on the Support page. For more information,
contact the Dell EMC Technical Assistance Center.
