Information About Migrating to a Cisco CRS-3 Carrier Routing
System
The difference between migrating a single-chassis Cisco CRS-1 Carrier Routing System to a
single-chassis Cisco CRS-3 Carrier Routing System and installing a new single-chassis Cisco CRS-3
Carrier Routing System is the fabric upgrade. A single-chassis Cisco CRS-1 Carrier Routing System
uses fabric cards designed for 40 GB operation (FC/S cards), and an LCC in a Cisco CRS-3 Carrier
Routing System uses fabric cards designed for 140 GB operation (FC-140G/S cards). On a single chassis
system, each fabric card represents one fabric plane. To migrate a single-chassis Cisco CRS-1 Carrier
Routing System to a single-chassis Cisco CRS-3 Carrier Routing System without interrupting service,
you must do the following:

Verify That the Correct Version of IOS-XR Software is Installed
The Cisco CRS-3 is only supported on Cisco IOS-XR release 4.0.0.T and higher software. As detailed
in the section
upgrade to Release 4.0.X(PX) is available for a router running Cisco IOS XR releases 3.8.0 through
3.9.0. All IOS-XR Software releases prior to 3.8.0 (IOS XR releases 3.4.2, 3.5.3, or 3.6.2) must be

Use CLI commands to prepare the FC/S fabric card for replacement with an FC-140G/S card.
Shut down the plane on the FC/S card before it is replaced.
Replace the FC/S card with an FC-140G/S card.
Bring up the FC-140G/S card.
Repeat Step 2 through Step 4 until all planes (0 through 7) are upgraded.
