Core Specifications of the C9300-48T-E=: High-Density Copper Without PoE Overhead
The Cisco Catalyst C9300-48T-E= is a 48-port Gigabit Ethernet Layer 3 switch designed for enterprises prioritizing high port density and 10G/25G uplink scalability without Power over Ethernet (PoE) requirements. Featuring 48x 1G RJ45 ports and four modular uplink slots, it supports flexible 1G/10G/25G connectivity via SFP modules. Pre-installed Cisco DNA Essentials licensing enables automated network management, while a 715W power supply ensures energy-efficient operations.
Key differentiators:
- Non-PoE design reduces costs in environments without power-hungry devices.
- StackWise-480 technology for 480 Gbps stacking bandwidth across up to eight switches.
- MACsec encryption secures data across untrusted network segments.
Feature Comparison: C9300-48T-E= vs. PoE and Fiber Switches
This model targets scenarios where copper density trumps PoE or fiber needs. Below is a breakdown against the C9300-48P-A (PoE) and C9300-48S-1A (fiber):
| Feature | C9300-48T-E= | C9300-48P-A | C9300-48S-1A |
|---|---|---|---|
| Port Type | 48x 1G RJ45 | 48x PoE+ RJ45 | 48x 1G SFP |
| Power Budget | 715W (switch operations) | 740W (PoE-focused) | 515W (fiber module support) |
| Ideal Use Case | Server farms, campus cores | High-density IoT/AP deployments | Data center fiber aggregation |
Addressing Critical User Questions
Q: Can this switch support PoE devices through external solutions?
A: Yes. While lacking built-in PoE, it pairs with midspan injectors or PoE switches like the C9300-48P-A for mixed environments.
Q: What uplink speeds are achievable?
A: Using 25G SFP28 modules, the switch supports spine-leaf architectures or high-bandwidth data pipelines.
Q: Is redundant power available?
A: Yes. Dual 715W AC/DC power supplies (sold separately) ensure uninterrupted operations in critical setups.
Q: What does DNA Essentials licensing include?
A: Automated QoS, basic threat detection, and SD-Access for network segmentation. For procurement, visit the [“C9300-48T-E=” link to (https://itmall.sale/product-category/cisco/).
Real-World Insight: Balancing Cost and Performance
In a recent deployment for a university’s research lab, the 48T-E=’s 48 copper ports connected legacy servers and workstations, while its 25G uplinks handled AI training data transfers. Unlike the 48P-A, which wasted PoE capacity here, or the 48S-1A’s fiber-centric costs, this switch delivered 30% lower TCO by avoiding unnecessary features. Its DNA Essentials tools also simplified compliance for grant-funded projects—proof that “less is more” when aligning hardware with actual needs. For enterprises where every dollar counts, the 48T-E= isn’t just a switch; it’s a strategic enabler of lean, future-ready networks.
