| Power | Power management configuration | The power management chapter in the System Management Configuration Guide provides detailed information on power management features and configurations available for Cisco 8100 Series Secure Routers. The features discussed include power-supply modes, and power-budgeting considerations. |
| 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 LEDs | Once 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 management | Energy Management dashboard | The 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 | Cisco 8100 Series Secure Routers monitor temperature and voltage to ensure optimal operation and system reliability. | |
| Materials, modularity, and reuse | Hardware standardization and modularity | Cisco 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. | |
| Cisco Takeback and Reuse | This program allows customers to return used equipment for responsible recycling and reuse. | |
| Cisco Refresh | This program offers certified remanufactured products, providing cost-effective alternatives to new equipment. | |
| Foam reduction | Cisco 8000 Series Secure Routers are packaged with corrugated and fiber flute materials, containing minimum 25% post-consumer recycled content. | |
| Accessory opt-in | Accessory opt-in allows customers to select whether to include the accessory kit. Not including the kit results in using fewer materials and reducing waste. The default is now to not include the kit unless it is required. | |
