Enterprise-grade 25G density, professionally tested, backed by 25+ years of trust.
This refurbished Cisco C9500-48Y4C-E is a Catalyst 9500 Series high-performance 48-port 25G switch running the Network Essentials license. It has been professionally tested and reset to factory defaults through WhaleyComm's ISO 9001-certified process. The unit delivers 48x 1/10/25G SFP28 downlink ports and 4x 40/100G QSFP28 uplink ports in a compact 1RU chassis, making it one of the highest-density 25G fixed-form-factor enterprise switches available in the Cisco portfolio.Powered by Cisco's UADP 3.0 ASIC, the C9500-48Y4C-E delivers up to 3.2 Tbps of nonblocking switching capacity and up to 1 Bpps of forwarding performance — purpose-built for enterprise campus core and aggregation deployments. The platform runs Cisco IOS XE, supports SD-Access, StackWise Virtual, MACsec 256-bit encryption, and VXLAN/EVPN, giving IT teams a fully programmable, automation-ready switching foundation. A 2.4-GHz quad-core x86 CPU with 16 GB DRAM underpins container-based application hosting and advanced telemetry.
WhaleyComm sources this unit at a fraction of new-list cost, allowing enterprise teams to deploy or expand 25G campus fabric without the capital exposure of new-purchase pricing. Every unit ships with a Lifetime Warranty and a Certificate of Testing — the same standard WhaleyComm has held for 25+ years across 5,000+ enterprise customers.

Ideal Use Cases
Enterprise Campus Core
The C9500-48Y4C-E delivers 3.2 Tbps of nonblocking capacity across 48 25G SFP28 ports, making it well-suited as the primary core switch in mid-to-large enterprise campus environments where high throughput and low latency are required.
Campus Aggregation / Distribution Layer
With 48 high-density downlink ports and 4x 100G QSFP28 uplinks, this switch excels as an aggregation node collecting traffic from multiple access-layer switches and routing it efficiently toward the core or WAN edge.
Data Center Edge or Top-of-Rack
The 25G SFP28 port density and 100G uplink support make the C9500-48Y4C-E a capable data center edge switch for server-facing or inter-rack connectivity in environments that have standardized on 25G server NICs.
SD-Access Fabric Node
Running Cisco IOS XE with SD-Access support, this switch integrates directly into Cisco DNA Center-managed fabric deployments as a border or distribution node, enabling policy-based automation and segmentation at scale.
StackWise Virtual High-Availability Pair
Two C9500-48Y4C-E units can be paired using Cisco StackWise Virtual technology to create a logical single-switch chassis with multichassis EtherChannel, eliminating spanning tree complexity and providing in-service redundancy.
Refurbished Infrastructure Refresh
Organizations seeking to modernize legacy 10G aggregation to 25G without full new-purchase pricing can deploy this professionally tested refurbished unit to achieve significant capital savings while maintaining enterprise performance standards.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The hardware is identical — both models share the same 48x 25G SFP28 ports, 4x 100G QSFP28 uplinks, UADP 3.0 ASIC, and 3.2 Tbps switching capacity. The suffix designates the software license: the -E model ships with Network Essentials and the -A model ships with Network Advantage. Network Advantage unlocks additional Layer 3 features including advanced MPLS, EVPN, and broader SD-Access capabilities. Contact our team if you need help selecting the right license tier for your environment.
The C9500-48Y4C-E includes the Network Essentials perpetual license for core switching functionality. A separate Cisco DNA (now Cisco Catalyst Center) subscription license is required if you intend to manage the switch through Cisco's DNA Center platform or access certain advanced automation features. WhaleyComm can advise on licensing options — call +1 214 607-4800 or email sales@whaleycomm.com.
Yes. The Cisco C9500-48Y4C-E supports Cisco StackWise Virtual technology, which allows two physical switches to operate as a single logical switch with multichassis EtherChannel and high-availability features. This is a common deployment for campus core and aggregation environments requiring nonstop operation.
Yes. Every WhaleyComm unit ships with a Lifetime Warranty. If it fails under normal operating conditions at any point, we replace it at no cost — no time limits, no questions asked.
Every unit goes through our ISO 9001-certified testing process: full power-on diagnostics, port-by-port functionality testing, firmware verification, factory reset, and final inspection. A Certificate of Testing ships with every unit.
