SFP-10G-SR++=: Enhanced Performance, Compatib
Technical Overview of SFP-10G-SR++= The ...
Core Features and Design Focus
The Cisco C9200L-48T-4G-1A is a Catalyst 9200 series access-layer switch optimized for non-PoE enterprise environments requiring high-density Gigabit connectivity and simplified uplink management. It offers 48x 1G RJ45 ports, 4x 1G/10G SFP+ uplinks, and a fixed 350W AC power supply, targeting budget-conscious deployments in offices, data centers, or retail networks.
Key Advantages:
- Cisco DNA Essentials: Pre-installed for 3 years, enabling zero-touch provisioning and network automation.
- StackWise Virtual: Supports up to 4 switches in a single logical stack for simplified management.
- Hardware Security: Trustworthy Systems and Secure Boot protect against firmware tampering.
Why This Model Fits Non-PoE Enterprise Needs
Organizations prioritizing wired connectivity without PoE requirements often seek balance between cost, scalability, and ease of use. Here’s how the C9200L-48T-4G-1A delivers:
1. High-Density 1G Ports for Wired Devices
The 48x 1G ports support connections for workstations, printers, and servers in environments where wireless or IoT devices are minimal.
2. Flexible Uplink Options
The 4x SFP+ slots allow 1G or 10G uplinks using cost-effective optics (e.g., SFP-10G-SR), enabling gradual backbone upgrades without replacing the entire switch.
3. Reduced Operational Complexity
Cisco DNA Center integration automates VLAN configurations, firmware updates, and policy enforcement, reducing IT workload for small to mid-sized teams.
Technical Specifications Overview
| Category | Details |
|---|---|
| Port Configuration | 48 x 1G RJ45, 4 x SFP+ (1G/10G) |
| Power Supply | Fixed 350W AC (no PoE support) |
| Stacking | StackWise Virtual (up to 4 switches) |
| Security | MACsec optional, Trustworthy Systems, Secure Boot |
Addressing Key User Concerns
Q: Can this switch support multi-gigabit devices?
No. The RJ45 ports are fixed at 1G, but the SFP+ uplinks support 10G for backbone scalability.
Q: Is it compatible with third-party transceivers?
Yes, using Cisco’s Generic Compatible Optics (GCO) program, but firmware updates may be required.
Q: How does StackWise Virtual improve redundancy?
By grouping switches into a single management domain, it enables hitless failover during upgrades or link failures.
Procurement and Licensing
For guaranteed authenticity and licensing compliance, purchase the “C9200L-48T-4G-1A” here. Verify SFP+ module compatibility (e.g., 1G vs. 10G) before deployment.
Final Assessment
The C9200L-48T-4G-1A is a pragmatic solution for enterprises prioritizing wired connectivity over PoE or multi-gig features. While its lack of PoE and fixed 1G ports limit flexibility for growing IoT deployments, the 10G uplink scalability and DNA Essentials licensing make it ideal for static environments like call centers or legacy data centers. For teams managing tight budgets with stable device requirements, this model offers Cisco-grade reliability without the premium cost of PoE or multi-gig hardware.
