C9300-48S-1E: What Makes Cisco’s Switch Ideal for High-Density Fiber Networks?



​Overview of the Cisco Catalyst C9300-48S-1E​

The ​​Cisco Catalyst C9300-48S-1E​​ is a high-performance Layer 3 switch optimized for enterprise networks requiring ​​high-density fiber connectivity​​ and low-latency performance. Tailored for data centers, campus cores, or bandwidth-intensive applications, it combines ​​48 SFP ports​​ with advanced automation features under Cisco’s DNA Essentials framework.


​Key Technical Specifications​

  • ​48x SFP Ports​​: Supports ​​1G/10G fiber modules​​, enabling flexible connectivity for servers, storage, or aggregation layers.
  • ​4x40G QSFP+ Uplinks​​: Provides high-speed stacking via ​​Cisco StackWise-480​​ (480 Gbps) or connectivity to core networks.
  • ​Cisco DNA Essentials​​: Includes ​​automated provisioning​​, ​​network health monitoring​​, and ​​basic security policies​​ via a subscription model.
  • ​Security Features​​: ​​MACsec encryption​​ and ​​Cisco TrustSec​​ for secure segmentation and role-based access control.

​Addressing Core User Questions​

​Q: Does the C9300-48S-1E Support PoE?​

No. The ​​“48S”​​ model uses ​​fiber SFP ports​​, which do not deliver Power over Ethernet. For PoE, consider the ​​C9300-48P-A=​​ (48x PoE+ copper ports).


​Q: How Does It Compare to the C9300-48H-A?​

  • ​Port Type​​: 48S-1E focuses on ​​fiber connectivity​​, while the 48H-A offers ​​48x Multigigabit copper ports​​.
  • ​Licensing​​: DNA Essentials (1E) vs. DNA Premier (A), limiting advanced features like SD-Access or encrypted traffic analytics.
  • ​Power Efficiency​​: Lacks UPOE support but consumes 20% less power than comparable copper-heavy models.

​Licensing and Scalability​

The ​​“-1E” suffix​​ denotes ​​DNA Essentials licensing​​, which includes:

  • ​Automated configuration backups​​ and real-time monitoring.
  • ​Lifetime hardware warranty​​ with 90-day Cisco TAC support.
    Upgrading to ​​DNA Advantage​​ or ​​Premier​​ unlocks AI-driven insights, SD-Access, and enhanced threat detection.

​Final Analysis​

The C9300-48S-1E excels in environments where fiber reliability and high port density are critical—think data center interconnects or media-rich campus backbones. While it lacks PoE and advanced licensing features, its 10G/40G readiness and DNA Essentials provide a cost-effective foundation for enterprises prioritizing low-latency, high-throughput fiber networks. For IT teams building scalable, future-proof fiber infrastructures without over-investing in unused PoE capacity, this switch is a strategic choice.
