Data center teams managing dense server environments need a reliable, line-rate Gigabit Ethernet top-of-rack switch that integrates seamlessly into an existing Cisco Nexus fabric — without compromising on performance or manageability. The Cisco N3K-C3048TP-1GE delivers exactly that.
Part of the Cisco Nexus 3000 Series, the Nexus 3048TP-1GE packs 48 x 10/100/1000 RJ-45 ports and 4 x 10GE SFP+ uplink ports into a compact 1RU form factor. With a 176 Gbps switching capacity and 132 Mpps forwarding rate, it provides line-rate Layer 2 and Layer 3 switching across every port — ideal for big data clusters, virtualized server farms, and general-purpose data center access layers. The switch runs Cisco NX-OS, the same data center-class operating system deployed across the broader Nexus portfolio, ensuring operational consistency and access to features like vPC, DCNM management, and comprehensive routing protocols.
This listing ships as a complete, deployment-ready unit with dual N2200-PAC-400W redundant AC power supplies, two AC power cords, a fan tray (N3K-C3048-FAN) configured for port-side exhaust airflow, and a rackmount/rail kit (N2200-ACC-KIT). Please note that the Cisco Nexus 3048 has reached End-of-Sale status, making pre-owned and refurbished units an excellent cost-effective option for spares, lab environments, or extending existing deployments.
Features & Benefits
Line-Rate Gigabit Ethernet Switching
The N3K-C3048TP-1GE delivers 176 Gbps of switching capacity and 132 Mpps forwarding across all 48 GbE ports and 4 SFP+ uplinks simultaneously. This means zero packet loss under full load — critical for latency-sensitive big data and virtualization workloads where every dropped frame impacts application performance.
10GE SFP+ Uplinks
Four 10 Gigabit Ethernet SFP+ uplink ports provide high-bandwidth connectivity to aggregation or spine-layer switches. Compatible with SFP+ direct-attach copper (Twinax) cables as well as multimode and single-mode optical transceivers, giving you flexible options for short-range and long-range uplink runs.
Cisco NX-OS with Integrated L2/L3 Switching
Running the proven Cisco NX-OS operating system, the Nexus 3048 ships with a comprehensive Layer 2 feature set including vPC, RSTP, MSTP, and private VLANs. Layer 3 unicast and multicast routing — including OSPF, EIGRP, BGP, and PIM — can be enabled with optional licenses, providing full inter-VLAN routing without an external router.
Redundant Power & Cooling
This unit includes two N2200-PAC-400W AC power supplies for 1+1 redundancy, ensuring uninterrupted operation if a PSU fails. The included fan tray (N3K-C3048-FAN) is configured for port-side exhaust airflow, aligning with standard hot-aisle/cold-aisle data center cooling designs.
Compact 1RU Form Factor
At just 1.72 x 17.3 x 19.7 inches and approximately 20.5 lbs, the Nexus 3048 maximizes port density per rack unit. The included N2200-ACC-KIT rackmount hardware enables fast, secure installation in any standard 19-inch rack or cabinet.
DCNM & Automation Support
The Nexus 3048 is supported by Cisco Data Center Network Manager (DCNM), providing centralized provisioning, monitoring, and troubleshooting. This simplifies day-2 operations and integrates the switch into broader Nexus fabric management workflows.
Deployment Scenarios
Data Center Top-of-Rack Access Layer
Deploy the N3K-C3048TP-1GE at the top of each server rack to provide 48 ports of 1GbE connectivity to rack-mounted servers, with 10GE uplinks to Nexus aggregation switches. Line-rate switching and low latency ensure consistent application performance across the fabric.
Big Data & Hadoop Cluster Connectivity
The Nexus 3048 is purpose-built for big data environments where large numbers of commodity servers require high-density, low-latency GbE connectivity. Its 9 MB shared buffer and jumbo frame support (up to 9216 bytes) handle the bursty, large-transfer workloads typical of MapReduce and HDFS traffic.
Lab, Staging & Development Environments
As an End-of-Sale product, refurbished N3K-C3048TP-1GE units offer exceptional value for non-production environments. Build out realistic Nexus lab topologies for NX-OS training, certification study, or pre-deployment testing at a fraction of the cost of current-generation hardware.
Network Traffic Monitoring & TAP Aggregation
With Cisco Nexus Data Broker support, the Nexus 3048 can serve as a scalable, cost-effective TAP or SPAN aggregation switch. Collect and distribute copies of production traffic to monitoring and analysis tools without deploying purpose-built matrix switches.
