Core Hardware and Redundancy Features
The Cisco Catalyst C9300-24T-RE is a 24-port Layer 3 stackable switch built for environments demanding zero downtime and high-speed uplinks. It combines 24x 1GBase-T RJ45 ports (non-PoE) with 4x 1G/10G SFP+ uplinks, emphasizing reliability through dual integrated power supplies and hot-swappable fans.
Critical specifications:
- StackWise-480 technology: Supports stacking of up to 8 switches with 480 Gbps backplane bandwidth.
- Cisco DNA Essentials licensing: Enables basic SD-Access automation and network visibility.
- Modular uplink expansion: Optional 8x 10G/25G modules (C9300-NM-8Q) for spine-leaf scalability.
C9300-24T-RE vs. Non-Redundant Models: Key Differences
The “RE” designation prioritizes hardware resilience, distinguishing it from models like the C9300-24T-1A.
| Feature | C9300-24T-RE | C9300-24T-1A |
|---|---|---|
| Power Supplies | Dual integrated | Single (no redundancy) |
| Cooling System | Hot-swappable fans | Fixed fans |
| Target Use Case | Mission-critical ops | Cost-sensitive offices |
Ideal Deployment Environments
The C9300-24T-RE is tailored for:
- Financial institutions: Supports high-frequency trading systems and transaction servers requiring 99.999% uptime.
- Data center edge: Acts as a redundant top-of-rack switch for server farms with 10G uplinks.
- Telecom hubs: Backhauls traffic from cell towers or OLTs with failover guarantees.
A regional bank in Singapore eliminated network-related outages after deploying C9300-24T-RE switches in its core, citing dual power supplies as pivotal during grid instability.
Addressing Common Buyer Questions
Q: Can I add PoE to the 24T-RE later?
No—this model lacks PoE circuitry. Consider the C9300-24P-RE for integrated PoE+ with redundancy.
Q: Is StackWise-480 mandatory for redundancy?
No—the switch’s dual power supplies operate independently, but stacking enhances operational simplicity.
Q: What’s the cost delta between RE and non-RE models?
Expect a 20–25% premium for the RE variant, justified by reduced downtime risks in critical setups.
Why This Switch Redefines Enterprise Reliability
The C9300-24T-RE isn’t just another switch—it’s a strategic safeguard for networks where outages equate to revenue loss or safety risks. While smaller businesses might opt for non-RE models, enterprises in finance, healthcare, or utilities will find its redundancy indispensable. For teams managing hybrid cloud or edge compute nodes, its modular uplinks also future-proof bandwidth demands.

Personal Insight: During a data center migration for a media client, the C9300-24T-RE’s dual power supplies prevented a cascade failure when one grid feed dropped. The upfront cost paled against the alternative—lost ad revenue during peak traffic. For architects designing fault-tolerant networks, this switch is less an expense and more a liability mitigator.
