Dell S-Series S4112T-ON Managed L2/L3 10G Ethernet (100/1000/10000) Rack Mountable in Black

Dell S-Series S4112T-ON – Managed L2/L3 10G Ethernet Switch

The Dell S-Series S4112T-ON is a high‑performance, rack‑mountable network switch designed for modern data centers and enterprise environments. It delivers robust Layer 2 and Layer 3 capabilities while supporting both copper and fiber connectivity at 10 Gb/s and 100 Gb/s speeds.

Key Design Highlights

• Form Factor: 1U rack‑mountable chassis in sleek black finish, ideal for dense deployments.
• Power: Dual AC input (100–240 V, 50–60 Hz) with a maximum consumption of 200 W, ensuring efficient operation even under full load.
• Cooling: Three high‑efficiency fans provide reliable airflow and maintain optimal operating temperatures.
• Reliability: Operates across a wide relative humidity range (10–85 %) and complies with the Harmonized System code 85176990 for global trade compliance.

Port Configuration

The switch features a balanced mix of copper and fiber interfaces, enabling flexible network topologies:

All copper ports support Auto‑MDI/MDIX, simplifying cable management. The QSFP28 modules are installed in the chassis, providing high‑density 100 GbE connectivity for spine or aggregation layers.

Layer 2 and Layer 3 Features

• Advanced Switching: Full support for VLANs (up to 4 000), spanning tree protocols, and MAC address learning.
• Routing Capabilities: Static routing, OSPF, BGP, and policy‑based routing allow the switch to function as a lightweight router in edge or core deployments.
• Quality of Service (QoS): Traffic shaping, priority queuing, and bandwidth management ensure critical applications receive the necessary resources.
• Security: Port security, 802.1X authentication, and ACLs protect against unauthorized access and traffic anomalies.

Management and Automation

The switch runs Dell’s OS10 operating system, offering a modern CLI, RESTful APIs, and NETCONF/YANG support. Key management features include:

• Out‑of‑Band Management: Dedicated management port for secure remote administration.
• SNMP v3, Syslog, and RMON: Comprehensive monitoring and alerting capabilities.
• Virtual Link Trunking (VLT): Provides active‑active redundancy across two switches without the need for STP.
• Automation Friendly: Integration with Ansible, Python scripts, and other automation frameworks streamlines configuration drift prevention.

Use Cases

• Data Center Fabric: The 12×10 GbE RJ‑45 ports serve as access or aggregation links, while the 3×100 GbE QSFP28 modules connect to spine switches, creating a scalable, low‑latency fabric.
• Enterprise Core: Layer 3 routing and high port density make it suitable for core routers in large campus networks.
• Edge Deployment: Its compact size and efficient power consumption allow deployment at branch offices or edge sites requiring 10 GbE connectivity.

Physical and Environmental Specifications

Software and Firmware

The switch ships with the latest Dell OS10 firmware, which includes:

• Enhanced security patches.
• Improved QoS algorithms.
• Support for new YANG models.
• Bug fixes that increase stability under heavy traffic loads.

Installation and Rack Integration

The 1U chassis is designed for straightforward rack mounting. It features:

• Standard 19‑inch width with a single U height.
• Front‑to‑back airflow design to maximize cooling efficiency.
• Integrated power supply connectors and fan headers for easy maintenance.

Conclusion

The Dell S-Series S4112T-ON delivers a compelling blend of performance, flexibility, and manageability. Its balanced port mix, robust Layer 2/Layer 3 stack, and modern OS10 software make it an excellent choice for data center fabrics, enterprise cores, and edge deployments that demand reliable 10 GbE and 100 GbE connectivity in a compact, rack‑mountable form factor.
