The Cisco 8100 Series Secure Routers are designed to simplify secure networking for small branch environments. By leveraging a new secure networking processor and a unified platform, these routers provide a balance of robust security, high performance, and flexible management options, including on-premises, cloud, or infrastructure-as-code deployments.

These devices are engineered to help businesses scale efficiently while reducing risk and ensuring future readiness. With a compact and energy-efficient design, the 8100 series is particularly well-suited for small sites, remote workers, and IoT applications that require reliable, enterprise-grade connectivity and advanced traffic prioritization.

Product overview

The Cisco 8100 Series encompasses a wide range of models tailored to specific connectivity needs, including the C8130-G2, C8130H-G2, C8130-VAI-G2, C8130-VAP-G2, C8131-G2, C8140-G2, C8151-G2, C8151-CVAI-G2, C8151-CVAP-G2, C8151H-C-G2, and the C8161-G2. These models vary in their port configurations, ranging from standard Gigabit Ethernet (GE) ports to specialized options like 10GE copper ports, XGSPON/10G BASE-T, and RJ-11 DSL interfaces.

Several models feature advanced connectivity options, such as embedded cellular modules for 5G RedCap or slots for pluggable interface modules (PIM) to support LTE and 5G. Additionally, specific units like the C8161-G2 offer Power over Ethernet (PoE/PoE+) capabilities. All models are built with a focus on sustainability, utilizing a fanless design for smaller units and a simplified architecture that consolidates components to reduce environmental impact and operational costs.

Sustainability profile

Cisco is embedding sustainability into the product lifecycle—from manufacturing to end of use. Designed with consideration for Cisco's Circular Design Principles, our products feature both individual and portfolio-wide programs and innovations, including those that address efficient architecture design, power consumption, energy management, packaging sustainability, and takeback. These elements are pivotal in reducing operational costs and advancing net-zero greenhouse gas (GHG) emissions targets, and other sustainability-related ambitions.

Information about Cisco's environmental, social, and governance (ESG) initiatives and performance is available in Cisco's Purpose Reporting Hub.

PowerPower management configuration

The power management chapter in the System Management Configuration Guide provides detailed information on power management features and configurations available for the Cisco 8100 Series Secure Routers. The features discussed include power-supply modes, and power-budgeting considerations.

Environmental Monitoring and PoE management

Auto-off ports without Small Form-factor Pluggable (SFP)Once enabled, the system checks for the presence of SFPs in Fiber ports on a regular basis and turns on SerDes when SFP is detected. If no SFP is detected, the system will keep SerDes off to save energy.
Auto-off port LEDsOnce enabled, port light emitting diodes (LEDs) will stay depowered, saving energy until a link event is triggered or manually enabled by the Command Line Interface or Mode button.
Energy managementEnergy Management dashboardThe Energy Management dashboard on the Catalyst SD-WAN Manager offers comprehensive energy management capabilities, allowing users to monitor energy usage, energy mix, costs, and greenhouse gas emissions in real time.

Energy Management
Environmental monitoring configuration

The environmental monitoring chapter in the System Management Configuration Guide provides guidelines for configuring monitoring of environmental conditions of chassis components.

Materials, modularity, and reuseHardware standardization and modularityCisco 8100 Series Secure Routers use standard subassemblies and common components across products to streamline production and enhance repairability and upgradability.
Simplified architecture

Cisco 8100 Series Secure Routers offer a simplified architecture by consolidating multiple discreet ASIC/NPU components into a central System-on Chip (SoC) architecture, providing multiple discrete functions in a more integrated design.

Powder-coat finish
Cisco 8100 Series Secure Routers use a powder coating finish instead of oil-based wet paint. In comparison, a powder-coating finish reduces the amount of harmful solvents used and Volatile Organic Compounds (VOCs) emitted during the painting process.
Bezel-free design
Cisco 8100 Series Secure Routers use a bezel free design reducing plastic usage.
