designing a customized shelf. We recommend that you use the rack-mount kit designed for
Cisco 7200 VXR routers.
Allow sufficient clearance around the rack for maintenance. If the rack is mobile, you can push it
back near a wall or cabinet for normal operation and pull it out for maintenance (installing or moving
port adapters, connecting cables, or replacing or upgrading components). Otherwise, allow 19
inches (48.3 cm) of clearance to remove Cisco 7200 VXR FRUs.
If you are planning to install the cable-management brackets on a Cisco 7200 VXR router that you
are rack-mounting from the front, you must install the cable-management brackets and the
rack-mount brackets before you install the chassis in the rack.
Provide an adequate chassis ground (earth) connection for your router chassis.
