Booting Up the Newly Downgraded Cisco CRS-1 Fabric
This section describes the process for booting up the new Cisco CRS-1 fabric.
When the Cisco CRS-1 fabric node is powered on, The Route Processor (RP) will automatically boot the
new fabric. Please wait for the boot process to complete. The node will transition from state MBI-BOOT
to MBI-RUNNING as the software is being installed.
When the boot process completes the node-state will be IOS-XR RUN.
