Introduction to the DS-C9396V-48ETK9P
The Cisco DS-C9396V-48ETK9P is a 48-port Catalyst switch designed for high-density enterprise and data center environments requiring scalable Power over Ethernet (PoE), Multi-Gigabit performance, and advanced security. Part of Cisco’s Catalyst 9300 Series, this modular switch supports 802.3bt PoE++, 40/100 Gbps uplinks, and Cisco DNA Software integration. It is engineered for campuses, IoT hubs, and hybrid cloud edge deployments where power efficiency, redundancy, and automation are critical.
Key Technical Specifications
- Port Configuration: 48 x 1/2.5/5/10 Gbps Multi-Gig Ethernet ports + 8 x 40/100 Gbps QSFP28 uplinks.
- PoE Budget: 2400W total, delivering 90W per port (802.3bt PoE++) for devices like Wi-Fi 6E APs, AV systems, and industrial sensors.
- Performance: 3.6 Tbps switching capacity with 2.7 Bpps forwarding rate.
- Stacking: StackWise-480 supports up to 8 switches in a single stack (4.8 Tbps per stack member).
- Security: Cisco TrustSec, MACsec encryption, and ISE 3.0 integration for zero-trust segmentation.
Primary Use Cases
The DS-C9396V-48ETK9P is optimized for:
- Enterprise Campuses: Powers lecture halls, conference rooms, and IoT-enabled buildings with high-density Wi-Fi 6E and digital signage.
- Healthcare Networks: Connects medical imaging devices, patient monitors, and telehealth endpoints with HIPAA-compliant encryption.
- Industrial Automation: Supports PLCs, AGVs, and machine vision systems with deterministic sub-1ms latency.

Addressing Critical User Concerns
Q: Can it support legacy and next-gen PoE devices simultaneously?
Yes. The switch auto-negotiates power budgets from 15W (802.3af) to 90W (802.3bt), ensuring compatibility with IP phones, cameras, and Wi-Fi 6E APs.
Q: How does StackWise-480 enhance reliability?
If a stack member fails, traffic reroutes within sub-200 milliseconds, maintaining uptime for real-time applications like VoIP and industrial controls.
Q: Is it compatible with hybrid cloud environments?
Yes. Integration with Cisco DNA Center and Intersight enables unified management across on-premises and cloud infrastructure.
Installation and Optimization Tips
- Power Redundancy: Deploy dual 1100W AC power supplies to maximize PoE availability during peak loads.
- Thermal Design: Maintain ambient temperatures below 40°C and use front-to-back airflow racks.
- QoS Configuration: Prioritize industrial protocols (e.g., PROFINET) and video conferencing traffic using FlexQoS.
