Disabling Power to the CRS-1 Fabric Card
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)
• ROMMON 1.54 or later version (for Route Processor [RP])
• ROMMON 1.52 or later version (for Dual Route Processor [DRP])
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 upgraded 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 Obtaining
Documentation, Obtaining Support, and Security Guidelines, page
v.
For more information, see Cisco IOS XR ROM Monitor Guide.

• This step brings up the previously shutdown plane,
which is now configured to use the FCC-CRS-3 fabric
card.
Step 6
end
Example:
RP/0/RP1/CPU0:router(admin-config)# end
Changes the mode from administration configuration mode
to administration EXEC mode.
Step 7
Repeat Step 3 through Step 6 for each fabric plane.
Step 8
