**Cisco SM-X-4X1G-1X10G Module: High-Density Connectivity for Modern Networks**  

Are you looking to upgrade your Cisco router’s interface capacity without sacrificing rack space? The **SM-X-4X1G-1X10G** module is a versatile solution for enterprises and service providers demanding both flexibility and scalability. Here’s a breakdown of its capabilities and why it’s a smart choice.  

---

**1. Performance Breakdown**  

While exact specs vary by router model, the SM-X-4X1G-1X10G typically delivers:  

- **Speed**: 4x1Gbps SFP ports + 1x10Gbps SFP+ port (ideal for mixed-speed environments).  

- **Latency**: <10μs for high-frequency trading or real-time video streaming.  

- **Power Efficiency**: <3W per port (optimized for energy-conscious deployments).  

---

**2. Key Differentiators**  

- **Density**: Combines 4x1G and 1x10G ports in a single compact module (saves valuable chassis slots).  

- **Versatility**: Supports copper (1000BASE-T) or fiber (OM3/OM4) via SFP/SFP+ transceivers.  

- **Redundancy**: Built-in link aggregation (LAG) and failover capabilities.  

- **QoS**: Prioritizes critical traffic (VoIP, video) with granular control.  

---

**3. Design & Aesthetics**  

- **Form Factor**: 1-slot module (fits Cisco 3900/3800/2900 Series routers).  

- **LED Indicators**: Per-port activity/status lights for quick troubleshooting.  

- **Durability**: Ruggedized metal casing for 24/7 operation in harsh environments.  

---

**4. User Experience**  

- **Ease of Use**: Plug-and-play installation; auto-negotiation for link speed/duplex.  

- **Management**: Configurable via CLI, SNMP, or Cisco DNA Center.  

- **Scalability**: Pair with additional modules for up to 16x10GE ports per router.  

---

**5. Pricing**  

Listed at **$1,800–$2,500 USD**, depending on region and licensing. Refurbished units often drop to $1,200–$1,500.  

---

**6. Battery Consumption**  

No onboard battery—draws power directly from the router (typically <1% of total power consumption).  

---

**7. Compatibility & Expansion**  

- **Supported Routers**: Cisco 3945E, 3925E, 3845, 2921, 2951 (with Supervisor Engine 32G).  

- **Software**: Requires Cisco IOS XE 3.13S or later.  

- **Expansion**: Combine with NIM-ES2-4G for 4x1GE stacking.  

---

**8. Software Support**  

- **Native Integration**: Works with Cisco Prime Infrastructure and NetFlow.  

- **Automation**: RESTCONF/YANG APIs for CI/CD pipelines.  

- **Lifecycle**: End-of-Sale (EoS) expected in 2028; EoL in 2030.  

---

**9. Why Choose SM-X-4X1G-1X10G?**  

- **Future-Proofing**: Prepares networks for 400G upgrades via disaggregated optics.  

- **ROI**: Reduces overspending on underutilized 10GE ports.  

- **Resilience**: Built-in loopback diagnostics for rapid fault isolation.
