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 switch specications, see Specications.
NOTE: Install the S5048F-ON switch in a rack or cabinet before installing the components.
Topics:
• Site selection
• Cabinet placement
• Rack mounting
• Switch ground
• Fans and airow
• Power
• Storing components
Site selection
Install the switch 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 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°C to 45°C (32°F to 113°F).
• Relative humidity is from 5 to 85 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 Specications.
Cabinet placement

Do not install the switch in outside cabinets. For cabinet placement requirements, see Site selection.
3
14 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 you ground your switch. Use the S5048F-ON switch in a common bond network (CBN).
Connect the grounding cables as described in S5048F-ON switch installation.
Fans and airow
The S5048F-ON switch fans support two airow options: normal and reverse.
Fan combinations
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 or DC PSU with fan airow from the I/O to the PSU—the red indicator is the normal airow direction
• AC or DC PSU with fan airow from the PSU to the I/O—the blue indicator is the reverse airow direction
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 S5048F-ON 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 S5048F-ON switches near each other, to permit proper airow, position the two switches at least 5
inches (12.7 cm) apart. The fan speed varies based on internal temperature monitoring. The S5048F-ON switch 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 cord. An AC power cord 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 you connect the power cord between the switch and the power source. 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 an AC switch, use the power supply cord as the main disconnect device. Ensure that the socket-outlet is located
and 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 15

Storing components
If you do not install your S5048F-ON switch and components immediately, properly store the switch and all optional components using
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 S5048F-ON switch and accessories. After you remove the original packaging, place the S5048F-ON switch
and components on an anti-static surface.

Rack or cabinet hardware 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, or threaded mounts. The ReadyRails system is provided for 1U front-rack and two-post installations.
The ReadyRails system includes separately packaged rail assemblies.
WARNING: This document is a condensed reference. Read the safety instructions in your Safety, Environmental, and Regulatory
information booklet before you begin.
NOTE: The illustrations in this document 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.
• 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 installed 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—Install the equipment in the rack so that the amount of airow required for safe operation of the equipment is not
compromised.
• 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 back panel facing downward.
ReadyRails installation
To easily congure your rack for installation of your S5048F-ON switch, use the ReadyRails rack mounting system provided.
You can install the ReadyRails system using the 1U tool-less method or one of three possible 1U tooled methods—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.
