How to Migrate to a Cisco CRS-3 Carrier Routing System (4-Slot)
To migrate from a 4-slot Cisco CRS-1 Carrier Routing System to a 4-slot Cisco CRS-3 Carrier Routing
System, you must complete the following tasks:
• Administratively Disabling the Fabric Plane, page 1-5
• Disabling Power to the CRS-1 Fabric Card, page 1-7.
• Physically Removing the CRS-1 Fabric Card, page 1-9
• Installing a CRS-3 Fabric Card, page 1-11.
• Verifying the Installation of a CRS-3 Fabric Card, page 1-15
The migration procedure may be done on one Fabric Card at-a-time.
In a CRS-1 system with redundant fabric (i.e. 8 planes), migration to CRS-3 fabric is hitless - zero drop
in traffic as we migrate plane by plane from a CRS-1 to CRS-3 .
The detailed migration procedure is detailed in the sections below, for the 4-slot Cisco CRS-3 Carrier
Routing System.
