Site preparations

The S4112-ON Series (S4112F-ON and S4112T-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 S4112-ON Series switch specications, see Specications.

NOTE: Install the switch into a rack or cabinet before installing any optional

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.

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 5° to 40°C

(50° to 104°F).

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

11

Cabinet placement

Install the S4112-ON Series switch only in indoor cabinets designed for use in a controlled

environment.

Do not install the S4112-ON Series 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 S4112-ON Series switch in a CBN.

For more information, see Ground cable.

Fans and airow

Fan installation is done as part of the factory install based on stock keeping unit (SKU)

type. The S4112-ON Series switch has SKUs that support the following congurations:

• AC PSU with PSU fan and system fans normal airow

• AC PSU with PSU fan and system fans reverse airow

• DC PSU with PSU fan and system fans normal airow

• DC PSU with PSU fan and system fans reverse airow

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.

12

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 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.

Storing components

If you do not install your S4112-ON Series 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° to

65°C (-40° to 149°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 S4112-ON Series

switch and its components on an anti-static surface.

13

1. Place the container on a clean, at surface and cut all straps securing the container.

2. Open the container or remove the container top.

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.

14

Ground cable

NOTE: For an AC-powered switch, although the third conductor of the AC power

cord provides a ground path, Dell EMC recommends grounding your switch with

a dedicated ground wire.

NOTE: For a DC-powered switch, the only way to safely ground your switch is to

attach a dedicated ground wire. The ground lug kit ships in a plastic bag placed

with the other accessories inside the shipping box. The ground lug bracket

screws ship attached to the switch. Before you install the DC switch in the dual-

tray, attach the ground lug and bracket to the switch using the included screws

and then attach the DC ground wire to the ground lug.

NOTE: The S4112-ON Series has a DC power source rated -40 to -72 VDC, 6A

minimum, Tma=40C, and an altitude operation of 3048m. The power cable is

10AWG, 16A minimum, with a 72V minimum rating.

The ground cable is not included. To properly ground the chassis, Dell EMC recommends a

one- or two-hole lug, M4 hole size. The ground lugs must be a UL-recognized, crimp-type

lug.

CAUTION: Grounding conductors

must

be made of copper. Do not use aluminum

conductors.

NOTE: Coat the one-hole lug with an anti-oxidant compound before crimping.

Also, bring any unplated mating surfaces to a shiny nish and coat with an anti-

oxidant before mating. Plated mating surfaces must be clean and free from

contamination.

NOTE: The rack installation ears are not suitable for grounding.

Before you install the switch into the dual-tray:

1. Cut the ground cable (not included) to the desired length. The cable length must

facilitate proper operation of the fault interrupt circuits. Use the shortest cable route

allowable.

2. Unscrew the two attached M4 screws and set aside.

3. Attach the ground lug and bracket to the switch using the M4 screws.

4. Using one of the two M4 threaded holes, attach the ground cable to the lug. Use the

M4 screw with a captive internal tooth lock washer. Torque the screw to ±5-6 in-lbs.

5. Attach the other end of the ground cable to a suitable ground point such as the rack

or cabinet.

The rack installation ears are not a suitable grounding point.

15

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. The dual-tray mounting rails ship with the dual tray, not

the switch.

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 rails 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 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 (113°F) 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.

Half-RU front-rack installation

The dual-tray mounting rails ship with the dual tray, not with the switch. You must supply

eight rack-mount screws for this four-post installation.

NOTE: Do not install the dual tray in a two-post rack.
