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 IOS XR Software Release 4.0.0.T or later release. If the router is brought up with an incompatible
version of the ROM Monitor software, then the standby RP may fail to boot. For instructions to overcome
a boot block in the standby RP in a single chassis system, see Cisco IOS XR ROM Monitor Guide. For
other issues, contact your Cisco Systems support representative for assistance. See
Documentation, Obtaining Support, and Security Guidelines, page
