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.

Only the authority responsible for the location can grant access to the restricted access area.

CAUTION

: Your switch is not NEBS Earthquake Z4-compliant if you use the 1U tool-less square-hole or two-post installation

methods.

CAUTION: Only trained and qualied personnel should install this equipment. Read this guide before installing and powering up

the system.

WARNING: The following information is a condensed reference. Read the safety instructions in your Safety, Environmental, and

Regulatory information booklet before you begin.

Ensure that the area where you install your system 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 temperature between 32° to 113°F (from 0° to 45°C).

• The switch operating ambient temperature range is from 0° to 45°C (from 32° to 113°F).

• Relative humidity is from 5 to 90 percent noncondensing.

• In a dry, clean, well-ventilated and temperature-controlled room, away from heat sources such as hot air ventilation outlets 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.

Site preparations 13

• 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.

Review these guidelines for rack mounting:

• Rack mounting—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 loading—Overloading or uneven loading of racks may result in shelf or rack failure and may damage the equipment or cause

possible personal injury. Stabilize the 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 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 equipment in a closed rack assembly, the operating temperature of the rack

environment may be greater than the room ambient temperature. The acceptable ambient temperature ranges are listed in

Specications under Environmental Parameters.

• Reduced air ow—Install the equipment in the rack so that you do not compromise the amount of airow required for safe operation of

the switch. For proper ventilation, position the chassis in an equipment rack or cabinet with a minimum of 5 inches (12.7 cm) of

clearance around exhaust vents.

• Reverse air ow—To ensure cool air intake and to avoid hot air blow out from the I/O side, ensure that you have the necessary

clearance.

• 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 PSU side facing in a downward position.

NOTE

: Always handle the system and its components with care. Avoid dropping the chassis or its eld replaceable units.

CAUTION: Always wear an electrostatic discharge (ESD) wrist or heel ground strap when handling a system and its components.

As with all electrical devices of this type, take all necessary safety precautions to prevent injury when installing this system. ESD

damage can occur if components are mishandled.

Cabinet placement

Install the S4048T-ON only in indoor cabinets designed for use in a controlled environment.

Do not install the S4048T–ON 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.

System ground

Dell EMC recommends you ground your system. Use the S4048T-ON in a common bond network (CBN).

Connect the grounding cable as described in Ground lug and bracket installation and Ground wire installation.

Fans and airow

The S4048T-ON fans support two airow options.

Site preparations

Fan combinations

Fans are installed as part of the factory install based on SKU type. The system has stock keeping units (SKUs) that support the following

congurations:

• AC or DC PSU with fan airow from the I/O to the PSU

• AC or DC PSU with fan airow from the PSU to the I/O

Be sure to order the fans suitable to support your site’s ventilation. Use a single type of airow fan in your system.

NOTE:

DO NOT

mix reverse and normal airows in a single S4048T-ON chassis.

For proper ventilation, position the system 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 systems 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 132.8°F (56°C) and decreases to normal speed when the

temperature falls to 127.4°F (53°C). The S4048T-ON never intentionally turns o the fans.

Power

To connect the chassis to the applicable power source, use the appropriate power cord.

• If the switch is an AC model, a country/region-specic AC power cord is included with each PSU.

• If the switch is a DC model, a country/region-specic DC power cord is included with each DC power kit.

When installing AC systems, follow the requirements of the National Electrical Code, ANSI/NFPA 70 where applicable.

The system is powered-up when the power cord is connected between the system 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 system. Ensure that the socket-outlet is located/

installed near the equipment and is easily accessible.

Storing components

If you do not install your system and components immediately, Dell EMC recommends properly storing the system 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).

• 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 S4048T-ON and its accessories. After you remove the original packaging, place the S4048T-ON and its

components on an antistatic surface.

Site preparations 15

NEBS compliance

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

To be NEBs compliant, orient your system in the rack so that the air inlet is from the front aisle and the air exhaust is from the rear aisle.

Important information

WARNING: The quad form-factor pluggable (QSFP), BaseT, console, Ethernet management, and universal serial bus (USB) ports

are suitable for connection to intra-building 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 intra-building interfaces only—Type 2 or

Type 4 ports as described in GR-1089-CORE, Issue 6. Also, 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 S4048T-ON to a commercial AC power source, you must connect the system to an

external special protection device (SPD).

WARNING: Use shielded intra-building cabling that is grounded at both ends for the 1/10GbE BaseT intra-building ports.

To be NEBS compliant, follow these regulations:

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

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

• You can also install and connect your system to the central oce.

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

• Ground your system using a copper ground conductor.

• Clean and coat all bare grounding connection points on your system with an anti-oxidant solution before making connections.

• Bring all unplated surfaces on your system to a bright nish and treat them with an anti-oxidant solution before making connections.

• Remove any non-conductive surfaces on your system from the threads and connection points to ensure electrical continuity.

• Use the two-hole, Listed, compression-type lug with an AWG 14 gauge wire that uses 4-in/lb to secure your system to the frame.

NOTE

: The S4048T-ON can operate at -40.5 to -60 VDC at a maximum current level of 24A or at 100–240 VAC at a maximum

current level of 7.1A.

NOTE: The S4048T-ON is Earthquake Z4-compliant when you attach the ReadyRails to the frame using threaded hardware. Do

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