Core Design of the C9300-48T-10A: High-Density Copper with 10G Scalability
The Cisco Catalyst C9300-48T-10A is a 48-port Gigabit Ethernet Layer 3 switch optimized for environments requiring high-speed copper connectivity and 10G uplink flexibility. Designed for non-PoE deployments, it features 48x 1G RJ45 ports and four modular uplink slots supporting 1G/10G/25G modules. With a 715W power supply and Cisco DNA Essentials licensing, it balances energy efficiency with advanced features like automated QoS and threat detection.
Key highlights:
- 10G-ready uplinks for seamless backbone integration.
- StackWise-480 technology, enabling 480 Gbps stacking across up to eight switches.
- MACsec encryption for securing data across untrusted networks.
Feature Comparison: C9300-48T-10A vs. PoE and Fiber Variants
This model prioritizes copper density and uplink versatility. Here’s how it contrasts with the C9300-48P-A (PoE) and C9300-48S-1A (fiber):
| Feature | C9300-48T-10A | C9300-48P-A | C9300-48S-1A |
|---|---|---|---|
| Port Type | 48x 1G RJ45 (non-PoE) | 48x PoE+ RJ45 | 48x 1G SFP |
| Power Budget | 715W (switch operations) | 740W (PoE-focused) | 515W (fiber module support) |
| Ideal Use Case | Server farms, office backbones | IoT, VoIP, and AP deployments | Data center fiber aggregation |
Addressing Key User Concerns
Q: Can this switch support PoE devices if needed?
A: No. However, it can be paired with external PoE injectors or PoE switches like the C9300-48P-A for hybrid setups.
Q: What uplink speeds are achievable?
A: Using 10G SFP+ or 25G modules in the uplink slots, it supports high-bandwidth spine-leaf architectures.
Q: Is redundant power available?
A: Yes. The switch supports dual 715W AC/DC power supplies (sold separately) for mission-critical redundancy.
Q: What’s included in DNA Essentials licensing?
A: It covers automated network segmentation, basic threat analytics, and Cisco SD-Access for policy enforcement. For procurement options, visit the [“C9300-48T-10A” link to (https://itmall.sale/product-category/cisco/).
Practical Insight: Where This Switch Delivers Unmatched Value
In a recent deployment for a financial firm’s trading floor, the 48T-10A’s 48 copper ports connected legacy trading terminals, while its 25G uplinks handled real-time data feeds to analytics servers. Unlike the 48P-A, which wastes PoE capacity in such setups, or the 48S-1A’s fiber-centric design, this switch eliminates unnecessary costs in copper-dominated environments. Its sub-150W idle consumption also aligns with sustainability goals—a growing priority for enterprises. While newer multi-gig models grab headlines, the 48T-10A remains a stalwart for IT teams needing reliability over hype, proving that sometimes, simplicity is the ultimate sophistication.
