Frequently Asked Questions
What are the primary port configurations of the Dell S4112T-ON? +
The Dell S4112T-ON is a high-density, half-width rackmount switch designed for demanding environments. It features 12 ports of 10GBase-T for copper connectivity, along with 3 ports of 100GbE QSFP28 uplinks. This configuration provides excellent flexibility for organizations needing high-speed server connectivity alongside high-bandwidth core or spine uplinks.
Does the S4112T-ON support Dell EMC Networking OS10? +
Yes, the S4112T-ON ships with Dell’s modern OS10 operating system. This modular, disaggregated software environment is built on a Linux kernel, offering deep programmability and native support for standard networking protocols. It is designed to streamline automated deployment and lifecycle management in modern data center infrastructures.
What is the airflow direction of the S4112T-ON model? +
This specific unit features an I/O to fan airflow configuration. This means the air intake is positioned on the port side, with the exhaust flowing out through the fan side. This orientation is ideal for data center aisles where hot and cold air containment is strictly regulated, ensuring optimal thermal performance.
Can the S4112T-ON switch be deployed in pairs for redundancy? +
Absolutely. The S4112T-ON is well-suited for Virtual Link Trunking (VLT) deployments. By pairing two switches, you can create a loop-free, multi-chassis link aggregation environment. This ensures high availability for your mission-critical applications and provides seamless path redundancy if one switch unit encounters a failure.
Does the S4112T-ON come with power supply redundancy? +
Each S4112T-ON unit is equipped with dual AC power supply units (PSUs). This redundant power configuration is critical for maintaining uptime in enterprise environments. By connecting these to separate power sources or circuits, you can effectively mitigate the risk of downtime caused by an individual power supply or circuit failure.
What are the typical use cases for the S4112T-ON switch? +
This switch is an ideal Top-of-Rack (ToR) solution for dense server environments. Its combination of 10GBase-T ports and 100GbE uplinks makes it perfect for high-performance computing clusters, virtualization environments, and storage area networks requiring a reliable, high-speed connection between server nodes and the core network fabric.
Are the 100GbE ports on the S4112T-ON compatible with 40GbE transceivers? +
The QSFP28 ports are designed to be backward compatible with 40GbE QSFP+ transceivers in many configurations. This allows network administrators to bridge existing 40GbE infrastructure into a modern 100GbE fabric without requiring an immediate, wholesale upgrade of all cabling and optic modules across the data center.
How does the S4112T-ON handle high-speed switching performance? +
The architecture of the S4112T-ON is engineered for low-latency, high-throughput environments. By utilizing advanced switching silicon, it supports non-blocking throughput across all ports. This ensures that latency-sensitive traffic, such as real-time database queries or high-frequency data transfers, is handled efficiently without introducing bottlenecks at the network edge.
