How to Migrate to a Cisco CRS-3 Carrier Routing System (4-Slot)
Administratively Disabling the Fabric Plane
This section describes how to migrate the fabric cards in a single-chassis system and establish
communications between the designated shelf controller (DSC) LCC and one or more FCCs.
Prerequisites
Software Requirements
• Cisco IOS XR Software Release 4.0.0.T or later release (Cisco IOS XR Software Release 4.0.2 for
multishelf nodes)

Caution The ROM Monitor software must be upgraded to version 1.54 or a later version on all RPs and/or
upgraded to version 1.52 or a later version on all DRPs before a Cisco
CRS-1 system is migrated to
Cisco
