On Cisco 12000 Series Routers that support switching capacity increases through switch fabric upgrades, there are some administrative considerations to observe after performing the upgrade and verifying its installation:

•The switch fabric upgrade does not include a new label that identifies the router by the new model number. The compliance label on the router chassis does not change. This could confuse technicians who might service the router in the future. Cisco recommends that the upgrade technician take any required administrative steps to make the new, post-upgrade router identity outwardly obvious.

•If steps are not taken to identify a router with upgraded switch fabric, the alternative methods for identifying an upgraded router are through either Cisco IOS software commands or the Cisco identification labels on the switch fabric cards (SFCs and CSCs) installed in the router. Table A-6lists the router models and their corresponding switch fabric card identification labels.
