Site preparations
The S4100–ON Series is suitable for installation as part of a common bond network (CBN).
You can install the system in:
•Network telecommunication facilities
•Data centers
•Other locations where the National Electric Code (NEC) applies
For more information about the S4100–ON Series specications, see Specications.
NOTE: Install the S4100–ON Series switch into a rack or cabinet before installing any optional components.

Site selection
Install Dell 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 S4100–ON Series switch meets the following safety requirements:
•Near an adequate power source. Connect the system to the appropriate branch circuit protection according to your local electrical
codes.
•Environmental—switch location—continuous temperature range is from 50° to 104°F (from 5° to 40°C).
•Operating humidity is from 5 to 85 percent noncondensing, 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.
For more information about switch storage and environmental temperatures, see Specications.
Cabinet placement
Install the S4100–ON Series only in indoor cabinets designed for use in a controlled environment.
Do not install the S4100–ON Series in outside cabinets. For cabinet placement requirements, see Site selection.
6Site preparations
The cabinet must meet minimum size requirements. Airow 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 recommends grounding your system. Use the S4100–ON Series switch in a CBN.
Fans and airow
The fans on the S4100–ON Series support two airow options: normal and reverse.
Fan combinations
Fan installation is done as part of the factory install based on SKU type. The S4100–ON Series has stock keeping units (SKUs) that support
the following congurations:
•AC PSU with fan airow from the I/O to the PSU—normal
•AC PSU with fan airow from the PSU to the I/O—reverse
•DC fan unit with airow from the I/O to the PSU—normal
•DC fan unit with fan airow from the PSU to the I/O—reverse
Be sure to order the fans suitable to support your site’s ventilation. Use a single type of airow fan in your system. Do not mix reverse and
normal airows in a single S4100-ON Series switch.
For proper ventilation, position the S4100–ON Series 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 S4100–ON Series never
intentionally turns o the fans.
Power
To connect the switch to the applicable power source, use the appropriate power cable. An AC power cable is included with the system.
When installing AC or DC systems, follow the requirements of the National Electrical Code ANSI/NFPA 70, where applicable.
The system is powered-up when the power cable is connected between the system and the power source.
CAUTION
CAUTION: On the AC system, 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 system powers up in ONIE.
: Always disconnect the power cable before you service the power supply slots.
