Every WhaleyComm unit is professionally tested, reset to factory defaults, and certified by our in-house engineers — the same standard trusted by 5,000+ organisations across 25 years. Not a refurb marketplace. A certified lifecycle partner.
Tested to factory specification. Backed by 25 years of enterprise trust.
This professionally tested and refurbished Cisco Nexus N3K-C3048TP-1GE is a line-rate Gigabit Ethernet top-of-rack (ToR) switch from the Cisco Nexus 3000 Series. Delivered in a compact 1RU fixed form factor, it provides 48 x 10/100/1000-Mbps RJ-45 ports and 4 x 1/10 Gbps SFP+ uplink ports, along with dual redundant AC power supplies for continuous high-availability operation. Every unit ships reset to factory defaults with a certificate of testing.The N3K-C3048TP-1GE delivers a switching capacity of 176 Gbps and a forwarding rate of 132 Mpps, achieving line-rate throughput on both Layer 2 and Layer 3 across all ports simultaneously. It runs Cisco NX-OS, a data center-class operating system built for modularity and resiliency, and supports advanced features including Virtual PortChannel (vPC), OSPF, EIGRP stub, LACP, jumbo frames (MTU up to 9216 bytes), and a MAC address table of 128,000 entries. Both forward and reversed airflow schemes are supported, making it easy to match your data center hot/cold aisle requirements.
The Cisco N3K-C3048TP-1GE from WhaleyComm delivers proven enterprise-grade ToR switching performance at a fraction of the original list price. Backed by our Lifetime Warranty and ISO 9001-certified testing process, this is a reliable, cost-effective upgrade or expansion unit for data center and campus edge environments.

Ideal Use Cases
Data Center Top-of-Rack (ToR) Access
The N3K-C3048TP-1GE aggregates 48 server or VM host connections at 1 GbE with four 10 GbE SFP+ uplinks to a spine layer, delivering non-blocking, line-rate forwarding for east-west traffic in high-density data center environments.
Big Data and Analytics Clusters
Cisco positions the Nexus 3048 as ideal for big data workloads requiring Gigabit Ethernet ToR switching that connects transparently to upstream Cisco Nexus switches — providing a consistent end-to-end Nexus fabric for HPC and analytics deployments.
Campus Wiring Closet / Access Layer
With 48 autosensing GbE access ports and 10 GbE uplinks in a 1RU footprint, this switch consolidates wired workstations, VoIP endpoints, and wireless APs into a single managed access layer switch — simplifying QoS policy and reducing rack space.
Enterprise Network Refresh or Expansion
Organizations expanding existing Nexus-based fabrics can add the N3K-C3048TP-1GE as a cost-effective access or aggregation node, leveraging vPC and FEX support for seamless integration with existing Nexus infrastructure.
Storage and Virtualization Environments
The switch's sub-microsecond latency, jumbo frame support (MTU 9216), and line-rate Layer 2/3 forwarding make it a strong fit for iSCSI storage traffic, VMware vSphere, and other latency-sensitive virtualization workloads.
High-Availability Lab or Staging Infrastructure
Dual redundant power supplies, redundant hot-swap fans, and NX-OS reliability features make this unit suitable for production-mirroring lab environments where hardware resilience matters without full new-hardware budget.
