Site preparations

The S4048–ON 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 S4048–ON specications, see Specications.

NOTE: Install the S4048–ON 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 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 and

access is controlled by the authority responsible for the location.

Ensure that the area where you install your S4048–ON switch meets the following safety requirements:

• Near an adequate power source. Connect the switch to the appropriate branch circuit protection as dened by your local electrical

codes.

• Environmental temperature between 32° to 113°F (from 0° to 45°C).

• The switch operating ambient temperature range is from 10° to 35°C (from 50° to 95°F).

• Operating humidity is from 5 to 85 percent non-condensing.

• Storage humidity is from 5 to 95 percent non-condensing.

• 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.

• Positioned in a rack or cabinet, or on a desktop with adequate space in the front, rear, and sides of the S4048–ON for proper

ventilation and access.

Cabinet placement

Install the S4048–ON only in indoor cabinets designed for use in a controlled environment.

Do not install the S4048–ON in outside cabinets. For cabinet placement requirements, see Site Selection.

12 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 you switch. Use the S4048–ON in a common bond network (CBN).

Connect the grounding cables as described in Install the S4048–ON.

Fans and airow

The S4048–ON fans support two airow options.

Fan combinations

The S4048-ON has stock keeping units (SKUs) that support the following congurations. Installation of the fans is done as part of the

factory install based on SKU type.

• AC PSU with fan airow from the I/O-side to the PSU-side

• AC PSU with fan airow from the PSU-side to the I/O-side

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 S4048–ON chassis.

For proper ventilation, position the S4048-ON 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 S4048-ON switches near each other, position the two chassis at least 5 inches (12.7 cm) apart to

permit proper airow. The fan speed increases when the internal temperature reaches 161.6°F (72°C) and decreases to normal speed

when the temperature falls to 136.4°F (58°C). The S4048-ON never intentionally turns o the fans.

Power

To connect the chassis to the applicable power source, use the appropriate power cord with the S4048–ON. An AC power cord is included

with the switch.

When installing AC 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.

CAUTION

: Always disconnect the power cable before you service the power supply slots.

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.

Storing components

If you do not install your S4048–ON and components immediately, Dell EMC recommends properly storing the switch and all optional

components by following these guidelines.

• Storage location temperature must remain constant ranging from -40° to 158°F (from -40°C to 70°C).

Site preparations

• 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 S4048–ON and its accessories. After you remove the original packaging, place the S4048–ON and its

components on an anti-static surface.

14 Site preparations

NEBS compliance

For your switch to be network equipment building system (NEBS) compliant, you must follow the instructions detailed in this section.

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.

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

sucient protection to connect these interfaces metallically to OSP wiring.

WARNING: If you install and connect the S4048-ON switch to a commercial AC power source, you must connect the switch to

an external special protection device (SPD).

To be NEBs compliant:

• Locate your switch in a restricted-access area were only trained personnel are allowed access.

• Install and connect your switch to the common bonding network (CBN).

• You can also install and connect your switch to the central oce.

• Connect the battery returns of your switch as DC-I.

• Ground your switch using a copper ground conductor.

• Clean and coat all bare grounding connection points on your switch with an antioxidant solution before making connections.

• Bring all unplated surfaces on your switch to a bright nish and treat them with an antioxidant solution before making connections.

• To ensure electrical continuity, remove any nonconductive surfaces on your switch from the threads and connection points.

• Use the two-hole, Listed, compression-type lug with an AWG 14 gauge wire for switch grounding.

NOTE

: The S4048–ON can operate at -40.5 VDC to -60 VDC at a maximum current level of 15A.

NOTE: The S4048-ON is Earthquake Z4-compliant when you attach the ReadyRails to the four-post frame using threaded

hardware. Do not use the tool-less or two-post installation methods.

Rack mount safety considerations

• Rack loading—Overloading or uneven loading of racks may result in shelf or rack failure, causing damage to the equipment and possible

personal injury. Stabilize racks in a permanent location before loading begins. Mount the components beginning 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 multiple electrical components are installed 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 rear panel facing in the downward position.

ReadyRails system installation
