Usage Features:

• Installation Flexibility: The switch can be installed in network telecommunication facilities, data centers, and other locations adhering to the National Electric Code (NEC). It supports installation in indoor cabinets designed for controlled environments.
• Rack Mounting: The S4112-ON Series can be mounted directly into a 19" wide, EIA-310-E-compliant rack or placed on a rack shelf. It supports half-RU front-rack installation using a dual-tray mounting system.
• Airflow Management: The switch offers configurations for normal or reverse airflow, with fan speeds varying based on internal temperature monitoring. A minimum of 5 inches (12.7 cm) clearance around exhaust vents is required for proper ventilation.
• Power Options: Supports both AC and DC power sources. AC power cables are included, while other power cables must be ordered separately. DC power connections involve a wiring block for secure wire insertion.
• Optical Transceivers: The equipment contains optical transceivers, which comply with Class 1 laser radiation limits. Specific instructions are provided for installing and removing optics, emphasizing eye protection and careful handling.
• Software Control: Module power is software controlled, meaning module LEDs may not be visible when the switch powers up in ONIE (Open Network Install Environment).
• Documentation and Support: Dell EMC provides extensive documentation, software upgrades, patches, and management software through its support site (www.dell.com/support). ONIE documentation is available at www.onie.org, and third-party software users should consult their respective documentation.

Maintenance Features:

• ESD Protection: Users are advised to wear ESD-preventive wrist or heel ground straps when handling the switch and its components to prevent electrostatic discharge damage.
• Grounding: Dell EMC recommends grounding the switch with a dedicated ground wire, even for AC-powered switches where the power cord provides a ground path. For DC-powered switches, a dedicated ground wire is essential for safety. Grounding conductors must be made of copper.
• Power Disconnection: Before servicing power supply slots, all power cords must be disconnected. For AC switches, the power supply cable serves as the main disconnect device and should be easily accessible.
• Component Storage: If not immediately installed, components should be stored in a constant temperature range of -40°C to 65°C (-40°F to 149°F), on a dry, anti-static surface, away from direct sunlight, heat, air conditioning ducts, and dust.
• Rack Safety: Rack loading should be balanced, and racks should be stabilized. Components should be mounted from bottom to top, ensuring the rack's load rating is not exceeded. Power sources and extension cords must not be overloaded.
• Environmental Monitoring: The operating environment's ambient temperature and airflow must be maintained within specified limits to ensure safe and proper operation.
• Battery Replacement: The device contains a lithium battery. Replacement should only be done with the same or equivalent type, and disposal must follow manufacturer's instructions to avoid explosion hazards.
• Optical Fiber Safety: When working with optical fibers, eye protection is mandatory, and users should never look directly into terminated or unterminated fiber or connector ends due to potential laser radiation exposure.
• Troubleshooting: The support site offers resources for technical support, including product-specific information accessible via a 7-character service tag or 11-digit express service code.
