Cisco XR 12000 Series Routers
A Next-Generation Routing Solution

For this project, Cicso wanted to update the aesthetics of all four members of the XR 12000 router family. The core of the project involved designing a new door system that could swing completely out of the way and be fully removed to access the internal cards and filters.

Every part of this complex design needed to play multiple functional roles and be sensitive to manufacturability, cost, EMI, air flow and aesthetics. For example, the door hinges on the 12406 model (pictured below left) not only secure the door, but they also anchor the cable management wire forms on the sides. Directly inside of this assembly is a sheetmetal bracket that not only mounts the hinges to the chassis, but also provides for rack-mounting of the chassis; all while maintaining the air flow through the chassis.

A sampling of some of the designed elements we designed or assisted with:

• Aluminum cast and machined hinges
• Sheetmetal rack mounts
• Filter cages
• Filter & honeycomb mounting and retention
• 4-bar sheetmetal filter mechanisms
• Wire-form cable management systems
• Door vibration control bumpers
• Center logo lighting
• Button and latch mechanisms
• Rail-to-face fastening
