Specifications
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-6 lists the router
models and their corresponding switch fabric card identification labels.
