Core Specifications of the C9300-48S-1A: Built for High-Density Fiber Networks
The Cisco Catalyst C9300-48S-1A is a 48-port Gigabit SFP Layer 3 switch engineered for environments demanding scalable fiber-optic connectivity. Optimized for data centers, service providers, and enterprise backbones, it features 48x 1G SFP slots and four modular uplink ports supporting 10G/25G/40G modules. With Cisco DNA Essentials licensing pre-installed, it enables automated network segmentation and policy enforcement while maintaining a 515W power supply for energy-efficient operations.
Key differentiators:
- Fiber-first architecture for low-latency, high-bandwidth data transit.
- MACsec encryption for secure communication over untrusted links.
- StackWise-480 technology, enabling 480 Gbps stacking bandwidth across eight switches.
Feature Comparison: C9300-48S-1A vs. RJ45 and PoE Models
This switch prioritizes fiber reliability over copper or PoE use cases. Below is a breakdown against the C9300-48P-A (PoE) and C9300-48H-1E (non-PoE RJ45):
| Feature | C9300-48S-1A | C9300-48P-A | C9300-48H-1E |
|---|---|---|---|
| Port Type | 48x 1G SFP | 48x PoE+ RJ45 | 48x non-PoE RJ45 |
| Power Budget | 515W (fiber module support) | 740W (PoE-focused) | 350W (switch operations) |
| Best Use Case | Data center aggregation, ISP edge | IoT campuses, VoIP systems | Legacy device connectivity |
Addressing Critical User Questions
Q: Can this switch support 10G uplinks without external hardware?
A: Yes. By inserting 10G SFP+ modules into its four uplink slots, it achieves high-speed backbone connectivity.
Q: Is redundant power available?
A: The base model includes one 515W PSU, but dual power supplies (AC or DC) can be added for failover scenarios.
Q: Does DNA Essentials cover advanced security?
A: It includes Cisco TrustSec for role-based access and Basic Malware Protection. For deeper analytics, upgrade to DNA Advantage.
Q: How does it handle legacy copper devices?
A: Use 1G SFP-to-RJ45 transceivers to connect copper-based equipment without sacrificing fiber backbone benefits. For procurement, visit the [“C9300-48S-1A” link to (https://itmall.sale/product-category/cisco/).
Field-Tested Insight: Where This Switch Becomes Essential
In a recent deployment for a regional ISP’s edge network, the 48S-1A’s 48 SFP ports streamlined fiber terminations for thousands of subscribers, while its 25G uplinks future-proofed bandwidth for 5G backhaul. Unlike the 48P-A, which wastes PoE capacity in fiber-dominant setups, or the 48H-1E’s copper limitations, the 48S-1A eliminates compromise in latency-sensitive environments. Its sub-3µs port-to-port latency also makes it ideal for financial trading floors—a niche where milliseconds dictate profitability. While fiber infrastructure demands upfront investment, the long-term ROI in reliability and scalability makes this switch a cornerstone for networks where copper simply can’t compete.
