Ensuring Easy Access to the Router
If your Cisco 7200 VXR router or Cisco uBR7246VXR router is installed in a standard 19-inch, 4-post 
or telco-type rack, cables from other equipment in the rack might obstruct access to the rear of the router. 
Also, rack power strips or other permanent fixtures may obstruct access to the router. Review the 
following guidelines to ensure easy access to the rear of the router when it is installed in a rack. If the 
router is not installed in a rack, or if you already have clear access to the rear of the router, proceed to 
the 
Use the following guidelines to ensure easy access to the rear of the router when it is installed in a rack:
  •
Ensure that you have at least 3 to 4 feet (0.91 to 1.22 meters) of working space at the rear of the 
router.
  •
If cables from other equipment in the rack fall in front of the rear end of the router, carefully gather 
the cables (using care not to strain or stress them) and use cable ties to anchor them away from the 
rear of the router.
  •
If access to the rear of the router is partially blocked by a power strip or some other permanent rack 
fixture, detach the router from the rack and carefully slide it forward until there is enough clearance 
to remove the power supply, the network processing engine, and the subchassis from the router. 
Detailed steps for detaching the router from the rack are contained in the
