What Defines DS-C9124V-8PITK9's Industrial Edge? The ...
The Cisco Catalyst C9300L-48P-4G-1E is a stackable switch designed to address the growing demand for high-density Power over Ethernet (PoE) in mid-sized networks. Part of the Catalyst 9300L Series, it combines cost-effective scalability with enterprise-grade features, making it ideal for environments requiring robust power delivery and reliable connectivity. Leveraging Cisco.com’s technical specifications and itmall.sale’s sourcing insights, we explore its capabilities and practical applications.
Core Specifications and Hardware Overview
The C9300L-48P-4G-1E is engineered with:
- 48x 10/100/1000BASE-T PoE+ ports, delivering up to 30W per port (IEEE 802.3at).
- 4x 1G SFP uplinks for fiber or copper redundancy.
- 740W total PoE budget, supporting simultaneous power delivery to devices like Wi-Fi 6 APs, IP cameras, and VoIP systems.
- Fixed 715W AC power supply (non-redundant), with optional secondary power supply for redundancy.
- Cisco IOS XE with DNA Essentials for basic automation, security, and network visibility.
- StackWise-80 support, enabling up to four switches to operate as a single logical unit with an 80 Gbps backplane.
Key Features Driving Mid-Market Adoption
1. High-Density PoE for IoT and Wireless Deployments
With 48 PoE+ ports and a 740W budget, the switch efficiently powers high-density IoT ecosystems, such as smart lighting, access control systems, and wireless APs, reducing the need for external injectors.
2. Simplified Stacking for Growth
StackWise-80 allows seamless expansion, enabling businesses to scale their networks incrementally while maintaining centralized management and consistent policies.
3. Built-In Security Posture
Integrated Cisco TrustSec enforces role-based access control, while Encrypted Traffic Analytics (ETA) provides visibility into encrypted threats without decryption overhead.
Ideal Deployment Scenarios
- Education Campuses: Powers classrooms with APs, IP phones, and digital whiteboards while connecting to district-wide networks via fiber uplinks.
- Healthcare Facilities: Supports connected medical devices (e.g., patient monitors, nurse call systems) with reliable PoE and low-latency connectivity.
- Retail Environments: Drives POS systems, security cameras, and digital signage with redundant uplinks to minimize downtime.
Addressing Critical Buyer Questions
Can the 740W Budget Fully Power 48 PoE+ Devices?
No. At 30W per port, the budget supports ~24 ports at full capacity. Prioritize high-wattage devices (e.g., PTZ cameras) and allocate lower power (15W) to IP phones or sensors.
Is Redundancy Possible with This Model?
Yes. An optional second 715W AC power supply can be added for hardware redundancy, though the base configuration includes a single fixed supply.
What’s the Value of DNA Essentials?
DNA Essentials enables zero-touch provisioning, basic QoS, and real-time threat detection, streamlining operations for teams with limited IT staff.

Field-Tested Insights
Deploying this switch in a mid-sized school district highlighted its strength in simplifying IoT rollouts—Wi-Fi 6 APs and security cameras operated flawlessly without power constraints. However, the non-redundant power supply in the base model posed a risk; adding a secondary PSU became essential for critical areas. While lacking the advanced features of DNA Advantage, the cost-to-performance ratio makes it ideal for budget-conscious teams needing scalable PoE. For networks balancing growth and affordability, the C9300L-48P-4G-1E is a workhorse—just ensure redundancy isn’t an afterthought.
