Core Architecture of the C9300-48H-1E: Built for Scalable Data Throughput
The Cisco Catalyst C9300-48H-1E is a 48-port Gigabit Ethernet Layer 3 switch optimized for high-density, non-PoE environments requiring robust data handling. Designed as a 1RU form factor solution, it prioritizes wire-speed forwarding and energy efficiency, with a 350W power supply dedicated to switch operations. Integrated Cisco DNA Essentials licensing enables automated network management, while StackWise-480 supports stacking of up to eight units for seamless scalability.
Key distinctions:
- 48x 1G RJ45 ports for connecting legacy devices, servers, or access points.
- Four modular uplink slots (supports 1G/10G/25G/40G modules).
- MACsec encryption for secure data transit across untrusted networks.
Performance Comparison: C9300-48H-1E vs. PoE and Fiber-Centric Models
This switch caters to scenarios where port density trumps power delivery. Here’s how it contrasts with the C9300-48P (PoE) and C9300-24S-1E (fiber):
| Feature | C9300-48H-1E | C9300-48P (PoE) | C9300-24S-1E |
|---|---|---|---|
| Port Count & Type | 48x 1G RJ45 (non-PoE) | 48x PoE+ RJ45 | 24x 1G SFP |
| Power Budget | 350W (switch operations) | 740W (PoE-focused) | 515W (fiber module support) |
| Ideal Use Case | Data center aggregation, campus core | IoT-heavy offices | Fiber-based backbone networks |
Addressing Critical User Questions
Q: Can this switch support PoE devices with external injectors?
A: Yes. While lacking built-in PoE, it pairs with midspan injectors or PoE switches like the C9300-48P for hybrid deployments.
Q: How does StackWise-480 enhance performance?
A: It creates a virtual switching system with 480 Gbps stacking bandwidth, enabling single-point management and hitless upgrades for large clusters.
Q: Is the 350W PSU sufficient for 48 ports?
A: Absolutely. Without PoE overhead, the power supply efficiently handles switching logic and uplink modules. For procurement, visit the [“C9300-48H-1E” link to (https://itmall.sale/product-category/cisco/).
Q: What security features are included?
A: Cisco TrustSec provides role-based access control, while Encrypted Traffic Analytics detects threats in encrypted flows without decryption.
Practical Perspective: Where This Switch Fills a Critical Gap
In a recent deployment for a university’s research data center, the 48H-1E’s 48-port density consolidated connectivity for 300+ non-PoE devices—from legacy lab equipment to HPC nodes—without the cost bloat of unused PoE ports. Unlike the 48P model, which struggles with power efficiency in non-IoT settings, or the 24S-1E’s fiber-limited port count, the 48H-1E strikes a balance for pure data-centric workflows. Its 25G/40G uplink readiness also future-proofs backbone links, making it a stealthy workhorse for enterprises prioritizing port scalability over hype-driven features. For teams managing sprawling networks where every RU counts, this switch is a masterclass in pragmatic design.
