Overview of the Cisco C9200-48T-E=
The Cisco Catalyst C9200-48T-E= is a fixed-configuration, Layer 3 switch designed for enterprise access and distribution layers. Part of the Catalyst 9200 series, it features 48 x 10/100/1000BASE-T ports and 4 x 1G SFP uplinks, targeting organizations needing high-density connectivity without Power over Ethernet (PoE) requirements. Its modular power supply and StackWise-160 support make it ideal for scalable, resilient network architectures.
Key Technical Specifications and Use Cases
- Port Configuration: 48 Gigabit Ethernet RJ45 ports + 4 SFP uplinks, optimized for data-only environments like server farms or VoIP backbones.
- Stacking Capability: StackWise-160 allows up to 8 switches to operate as a single logical unit, delivering 160 Gbps stacking bandwidth for simplified management.
- Energy Efficiency: EnergyWise technology reduces power consumption by up to 25% compared to older Catalyst 2960X models.
- Security: Integrated Cisco TrustSec and MACsec encryption for secure data transmission.
C9200-48T-E= vs. PoE Models: When Does It Fit Best?
| Feature | C9200-48T-E= | C9200-48P (PoE Model) |
|---|---|---|
| Power Focus | Data traffic only | PoE+ for devices (up to 30W/port) |
| Cost | Lower upfront cost | Higher due to PoE hardware |
| Use Case | Data centers, core networking | IoT, wireless AP deployments |
| Power Supply | 350W fixed | 435W/740W for PoE loads |
Deployment Scenarios: Where to Leverage the 48T-E=
- Enterprise Core Networks: Connects non-PoE devices like servers, routers, and storage systems with low-latency forwarding.
- Branch Offices: Provides cost-effective, high-port-density switching for desktop and printer fleets.
- Hybrid Cloud Backbones: Integrates with Cisco SD-Access for seamless policy enforcement across on-prem and cloud resources.
Addressing Common User Concerns
Q: Can the 48T-E= be upgraded to support PoE later?
A: No—its hardware lacks PoE circuitry. For PoE needs, choose the 48P or 48PXG variants upfront.
Q: Is StackWise-160 backward-compatible with older StackWise versions?
A: No. StackWise-160 requires all switches in the stack to be Catalyst 9200/9300 models.
Sourcing the C9200-48T-E=: Balancing Cost and Reliability
For enterprises prioritizing budget without sacrificing enterprise-grade performance, the C9200-48T-E= is available through itmall.sale. Their Cisco-certified refurbished units include validated firmware and optional extended warranties, often costing 40–60% less than new units—ideal for scaling large deployments.
Practical Insights from Network Architects
Having deployed the 48T-E= in financial data centers, its zero-touch provisioning via Cisco DNA Center significantly reduced rollout time for 500+ switch installations. However, its lack of PoE limits flexibility in dynamic environments—ensure your device mix remains static. For pure data traffic, its 7.68 Mpps forwarding rate and sub-3µs latency outperform legacy models, but always pair it with redundant power sources to maximize uptime.
