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 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 50° to 104°F (from 5° to 40°C).

• 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 Specications.

Cabinet placement

Install the S4100–ON Series (S4128F-ON and S4148F-ON) 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.

16 Site preparations

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 S4100–ON Series switch in a CBN.

Fans and airow

The fans on the S4100–ON Series (S4128F-ON and S4148F-ON) support two airow options: normal and reverse.

Fan combinations

Fan installation is done as part of the factory install based on SKU type. The S4100–ON Series has stock keeping units (SKUs) that support
the following congurations:

• AC PSU with fan airow from the I/O to the PSU—normal

• AC PSU with fan airow from the PSU to the I/O—reverse

• DC fan unit with airow from the I/O to the PSU—normal

• DC fan unit with airow 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 airow fan in your switch. Do not mix reverse and
normal airows in a single switch.

For proper ventilation, position the S4100–ON Series 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.

For more information, see Fans.

Power

Connect the switch to the applicable power source using the appropriate power cable. An AC power cable is included with the system.

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.

For more information, see Power supplies.

CAUTION

Before servicing, ensure all power cords are disconnected.

: Always disconnect the power cable before you service the power supply slots. The switch has multiple power cords.

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 17

Storing components

If you do not install your S4100–ON Series (S4128F-ON and S4148F-ON) swtich 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 149°F (-40° to 65°C).

• 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 S4100–ON Series switch and its accessories. After you remove the original packaging, place the switch and
its components on an anti-static surface.

5 Inspect the product and accessories for damage.

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

information booklet before you begin.

NOTE: The illustrations in this section are not intended to represent a specic switch.

NOTE: Do not the use the mounted ReadyRails as a shelf or a workplace.

Safety, Environmental, and Regulatory

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 specied 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 maximum ambient temperature of the switch.

• Reduced air ow—Do not compromise the amount of airow required for safe operation of the equipment. Install the equipment in the
rack so that the equipment constantly has the correct amount of airow 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 congure your rack for installation of your S4100–ON Series (S4128F-ON and S4148F-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.
The tooled installation methods include two-post ush 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.

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 Pass from the boot loader.

2 Search locally attached storage devices for one of the ONIE default installer lenames—for example, USB.

3 Exact URLs from DHCPv4.

4 Report inexact URLs based on the DHCPv4 responses.

5 Query to the IPv6 link-local neighbors using HTTP for an installer.

6 Start TFTP waterfall—from the DHCPv4 option 66

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
address 192.168.3.10/255.255.255.0.

To display the IP address, use the ifconfig eth0 command, as shown.

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 eects of EEE on the environment and human health
due to the potential presence of hazardous substances in EEE.
