Site preparations
The S5048F-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 S5048F-ON switch specications, see Specications.
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 airow
• 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.
2
Site preparations 7

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
Specications.
Cabinet placement
Install the S5048F-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. 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 S5048F-ON switch in a CBN.
8Site preparations

Fans and airow
Fan installation is done as part of the factory install based on stock keeping unit (SKU) type.
The S5048F-ON switch has SKUs that support the following congurations:
• AC fan unit with fan airow from the I/O to the PSU—normal
• AC fan unit 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 fan 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 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 that 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 S5048F-ON 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 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 S5048F-ON switch
and its components on an anti-static surface.

1 Place the container on a clean, at surface and cut all straps securing the container.
2 Open the container.
3 Carefully remove the switch from the container and place it on a secure and clean
surface.
4 Remove all packing material.
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
Safety, Environmental, and Regulatory 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.
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.
12 S5048F-ON switch installation

• 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 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 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.
NOTE: For more installation instructions, see the installation labels attached to the
rail assembly.
