Core Specifications and Design

The ​​Cisco Catalyst C9300L-48T-4G-10E​​ is a 48-port Layer 3 switch optimized for data-centric environments where Power over Ethernet (PoE) isn’t required. It features ​​48x 1G Base-T ports​​ and ​​4x 1G SFP uplinks​​, powered by a ​​715W AC power supply​​. The “10E” designation indicates inclusion of Cisco’s ​​Enhanced Permanent License​​, providing lifetime access to advanced Layer 3 routing and security features without recurring fees.

Key Benefits Over PoE-Capable Models

• ​​Cost Efficiency​​: Eliminates PoE hardware costs, making it 20–30% cheaper than PoE variants like the C9300L-48P-4X-10E.
• ​​Simplified Power Management​​: With no PoE load, the 715W PSU focuses solely on switch operations, reducing heat output and cooling demands.
• ​​StackWise-320 Support​​: Delivers ​​320 Gbps stacking bandwidth​​ for scalable deployments, matching the performance of higher-tier models.

Addressing Deployment Questions

​​Q: Can this switch support future PoE upgrades?​​
No. The ​​C9300L-48T-4G-10E lacks PoE circuitry​​, making it unsuitable for IP phones, cameras, or wireless APs. For mixed-use environments, consider PoE models like the C9300L-48P-4X-M.

​​Q: Are the 1G uplinks sufficient for high-bandwidth applications?​​
While the 4x 1G SFP uplinks handle basic traffic, bandwidth-intensive tasks (e.g., video backups or VM migrations) may require 10G-capable switches like the C9300L-48T-4X-10E.

Optimal Use Cases

• ​​Data center edge​​: Connects servers and storage systems in non-PoE racks.
• ​​Branch offices​​: Provides cost-effective switching for desktop PCs, printers, and legacy equipment.
• ​​Industrial control systems​​: Supports PLCs and sensors in environments with separate power infrastructure.

Licensing and Procurement

The built-in ​​Enhanced Permanent License​​ covers features like OSPF, EIGRP, and ACLs without subscriptions. For guaranteed hardware warranties and firmware updates, source the switch from authorized suppliers like itmall.sale. Avoid third-party SFP modules to ensure compatibility.

Hands-On Experience

Deploying the C9300L-48T-4G-10E in a financial data center revealed its strength in predictable, data-only workflows. While lacking PoE flexibility, its operational stability and lower TCO made it a pragmatic choice for organizations with segregated power and data networks. For enterprises prioritizing future-proofing over cost savings, however, PoE-ready switches remain the safer long-term investment.
