Specifications

Description:

Dell S3048-ON-RA is a high-density 1GbE Layer 2/3 fixed-port switch designed for enterprise edge, campus aggregation, and out-of-band management roles. It features 48x 1 Gigabit Ethernet RJ45 ports and 4x 10 Gigabit Ethernet SFP+ uplinks, making it suitable for cost-efficient, high-availability networking. Offering a switching capacity of 260 Gbps (full-duplex) and a forwarding rate of 131 Mpps, this switch is built for rapid and reliable packet handling in environments with large user counts and moderate bandwidth demands. With 80,000 MAC address support and low latency of 3.7 microseconds, the S3048-ON is ideal for scalable edge deployments. It comes with back-to-front airflow (PSU to I/O panel), aligning with hot/cold aisle best practices in data center and server room environments.

Features

High-Density 1GbE Access: 48x 1G RJ45 ports provide ample server, desktop, or IP device connectivity using standard copper cabling.
Scalable 10GbE Uplinks: 4x SFP+ ports enable high-speed uplinks to aggregation/core switches.
OS9 Network Operating System: Built-in Dell OS9 supports robust Layer 2/3 features, including VLANs, OSPF, BGP, and ACLs.
Stacking Capability: Supports up to 6 switches in a stack via dedicated stacking ports (cables sold separately).
Enterprise-Ready Hardware: Hot-swappable power supply slot (1x included, 2 total slots), fan modules, and compact 1RU form factor.
Efficient Airflow Design: Reversed airflow (PSU to I/O panel) supports modern data center cooling configurations.
