Tested
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 C9300-48T-A is a 1RU, enterprise-class access layer switch from the Catalyst 9300 Series — one of the most widely deployed stackable switching platforms in enterprise networking. Equipped with 48 × 10/100/1000 RJ-45 data-only (non-PoE) downlink ports, this unit ships reset to factory defaults and verified fully operational across all ports, delivering the same hardware performance as new at a significant cost reduction.Built on Cisco's UADP 2.0 ASIC and powered by an x86 CPU complex with 8 GB DRAM and 16 GB flash storage, the C9300-48T-A delivers 256 Gbps non-blocking switching capacity and a forwarding rate of 190.48 Mpps — wire-speed for both IPv4 and IPv6. The switch features a single modular uplink bay supporting optional network modules (C9300-NM-4G, C9300-NM-8X, C9300-NM-2Q, C9300-NM-4M, C9300-NM-2Y) to tailor uplink speed and media type. Running Cisco IOS XE with the Network Advantage license tier, the platform includes SD-Access, MACsec AES-256 encryption, 802.1X, Flexible NetFlow, Encrypted Traffic Analytics (ETA), NETCONF/RESTCONF, and embedded wireless controller capability. StackWise-480 technology supports stacking up to 8 units with 480 Gbps bidirectional stacking bandwidth and sub-50ms failover for campus-wide resiliency.
At $1,699, this refurbished C9300-48T-A represents exceptional value versus a new unit list price of over $3,800 — without compromise on performance or reliability. Every unit is backed by WhaleyComm's Lifetime Warranty and our ISO 9001-certified testing process, trusted by 5,000+ enterprise customers over 25+ years.

Ideal Use Cases
Enterprise Campus Access Layer
The C9300-48T-A delivers wire-speed 1G connectivity across 48 ports in a 1RU footprint, making it the ideal access-layer switch for corporate campus buildings that require dense wired endpoint coverage without inline power.
High-Density Wired Endpoint Environments
Environments with large numbers of desktops, thin clients, printers, IP phones (with external power), or lab workstations benefit from the 48 data-only ports, eliminating unnecessary PoE costs and heat output.
SD-Access Fabric Deployments
Running Cisco IOS XE with Network Advantage, this switch is a verified Cisco Software-Defined Access (SD-Access) fabric edge node — ideal for organizations deploying intent-based networking and zero-trust segmentation using Cisco Catalyst Center.
Stackable Core or Distribution Upgrade
StackWise-480 allows up to 8 units to be stacked with 480 Gbps bidirectional bandwidth and sub-50ms failover, making this an excellent building-block for resilient, high-capacity distribution or collapsed-core designs.
Budget-Conscious Network Refresh
Organizations refreshing aging Catalyst 3850 infrastructure gain a direct, backwards-compatible upgrade path to the Catalyst 9300 platform at a fraction of new-unit cost, with the same IOS XE feature set and modular uplink flexibility.
IoT and Security-Focused Networks
With hardware-anchored Secure Boot, MACsec encryption, Flexible NetFlow, and Encrypted Traffic Analytics, the C9300-48T-A is suited for networks that require rigorous endpoint classification, threat detection, and compliance enforcement.

The C9300-48T-A has one modular uplink bay that accepts Cisco Catalyst 9300 network modules, including the C9300-NM-4G (4 × 1G SFP), C9300-NM-8X (8 × 10G SFP+), C9300-NM-2Q (2 × 40G QSFP+), C9300-NM-4M (4 × Multigigabit), and C9300-NM-2Y (2 × 25G SFP28). Existing Catalyst 3850 network modules are also supported. The module is ordered separately and is not included by default.
No — the C9300-48T-A is a data-only model with no PoE capability on any downlink port. The switch ships with one PWR-C1-350WAC power supply installed in Bay 1; a second power supply (PWR-C1-350WAC, PWR-C1-715WAC, or PWR-C1-1100WAC) can be added in the second slot for redundancy and is ordered separately.
Using Cisco StackWise-480, up to 8 C9300 units can be stacked together, delivering 480 Gbps of bidirectional stacking bandwidth. The combined switching capacity reaches 736 Gbps and forwarding rate reaches 547.62 Mpps in a full stack, with NSF/SSO support for sub-50ms failover.
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.
