Materials,
modularity,
and reuse
Hardware
standardization and
modularity
Cisco 8400 Series Secure Routers use standard subassemblies and common components across products to streamline production and enhance repairability and upgradability.
Simplified
architecture
Cisco 8400 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 8400 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 designCisco 8400 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.

Takeback and Reuse Program

Cisco Refresh 

This program offers certified remanufactured products, providing cost-effective alternatives to new equipment.

PackagingRemoval of single-
use plastic bags
The Cisco 8400 Series Secure Routers are packaged with kraft paper materials, removing single-use plastic bags.
Foam reduction

Cisco 8000 Series Secure Routers are packaged with corrugated and fiber flute materials, containing minimum 25% post-consumer recycled content.
