Breaking Down the Cisco Catalyst C9300-24UB-E=
The Cisco Catalyst C9300-24UB-E= is a 24-port Layer 3 switch tailored for networks prioritizing flexible high-speed uplinks and simplified licensing. Part of the Catalyst 9300 Series, it integrates a pre-installed 40G/100G network module and Cisco DNA Essentials subscriptions to address bandwidth-hungry environments.
Technical Specifications and Hardware Highlights
- Ports: 24 x 1G Base-T RJ45 ports + 4 x 1G/10G SFP+ uplinks + 1 x pre-installed C9300-NM-8X network module (supports 8x10G, 4x25G, or 2x40G/100G connections).
- Power Supply: 715W AC with ENERGY STAR® compliance, reducing operational costs in always-on deployments.
- Licensing: Includes 5-year Cisco DNA Essentials, covering automation, analytics, and security updates without additional renewal fees.
Critical Features Driving Adoption
1. Pre-Configured High-Density Uplinks
Unlike standard Catalyst 9300 models, the 24UB-E= ships with the C9300-NM-8X module, enabling immediate deployment of 40G/100G spine-leaf connections or 25G server links without separate hardware procurement.
2. Extended Software Licensing
The 5-year DNA Essentials bundle supports long-term IT planning, providing tools like Cisco DNA Center integration for policy-based automation and AI-driven network insights.
3. Energy-Efficient Design
Using Cisco UPOE (Universal Power Over Ethernet) readiness, the switch dynamically adjusts power allocation to connected devices, ideal for IoT-heavy environments or offices deploying PoE lighting/security systems.
C9300-24UB-E= vs. C9300-24U-E (Base Uplink Model)
| Feature | C9300-24UB-E= | C9300-24U-E |
|---|---|---|
| Network Module | Pre-installed (8x10G) | Requires separate purchase |
| License Duration | 5-year DNA Essentials | 3-year subscription |
| Target Use Case | Data centers, high-density edge | Mid-market uplink needs |
Ideal Use Cases for the 24UB-E= Model
- Cloud-ready enterprises deploying spine-leaf topologies needing plug-and-play 40G/100G uplinks.
- Managed service providers requiring automated, energy-efficient infrastructure for multi-tenant environments.
- Organizations scaling IoT deployments where unified PoE and high-speed backhaul are critical.

Final Perspective on Cost vs. Value
The C9300-24UB-E=’s primary advantage lies in eliminating hidden costs—like modular add-ons and license renewals—that inflate budgets over time. While its initial price is higher than base models, the 5-year licensing and pre-bundled uplinks future-proof upgrades. In my experience, this model is a strategic fit for teams lacking specialized procurement resources but needing enterprise-grade performance. It might be overkill for small offices, but for enterprises balancing growth and operational simplicity, it’s a pragmatic gateway to scalable infrastructure.
