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.
