Site preparations

The S4200-ON Series (S4248FB-ON and S4248FBL-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 specifications, see Specifications.

NOTE: Install the S4200-ON Series switch in a rack or cabinet before installing any optional components.

Topics:

•Site selection

•Cabinet placement

•Rack mounting

•Switch ground

•Fans and airflow

•Power

•Component storage

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. The authority responsible for the location controls access to the restricted area.

Ensure that the area where you install your S4200-ON Series 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° to 45°C (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 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 Specifications.

Cabinet placement

Install the S4200-ON Series (S4248FB-ON and S4248FBL-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. Airflow 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.

Site preparations

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 S4200-ON Series switch in a CBN.

Connect the grounding cables as described in S4200–ON Series Installation.

Fans and airflow

The S4200-ON Series (S4248FB-ON and S4248FBL-ON) switch fans support two airflow options: normal and reverse.

Fan combinations

Installation of the fans is done as part of the factory install based on stock keeping unit (SKU) type. The S4200-ON Series has SKUs that support the following configurations:

●AC or DC PSU with fan airflow from the I/O to the PSU—the red indicator is the normal airflow.

●AC or DC PSU with fan airflow from the PSU to the I/O—the blue indicator is the reverse airflow.

Be sure to order the fans suitable to support your site’s ventilation. Use a single type of airflow fan in your switch. Do not mix reverse and normal airflows in a single S4200-ON Series 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 S4200-ON Series switches near each other, to permit proper airflow, position the two switches at least 5 inches (12.7 cm) apart. The fan speed varies based on internal temperature monitoring. The S4200ON Series never intentionally turns off the fans.

For more information, see Fans.

Power

Use the appropriate power cord with the S4200-ON Series (S4248FB-ON and S4248FBL-ON) when connecting the switch to the power source. An AC power cord is included with each PSU.

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 cord is connected 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: Use the power supply cord as the main disconnect device on the AC switch. Ensure that the socketoutlet 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.

Component storage

If you do not install your S4200-ON Series (S4248FB-ON and S4248FBL-ON) switch and components immediately, properly store the switch and all optional components by following these guidelines:

● Storage location temperature must remain constant. The storage range is from -40°C to 70°C (-40°F to 158°F).

14 Site preparations

●Store on a dry surface or floor, 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 S4200-ON Series switch and its accessories. After you remove the original packaging, place the S4200-ON Series switch and its components on an anti-static surface.
