Router Performance Upgrades and Model Identification
The compliance information label on the side of the chassis also identifies the
Cisco XR 12000 Series Router by its model number. The model number indicates
the router is in the Cisco XR12000 Series, the maximum switching capacity the
router supports, and the number of line card and RP slots in the chassis.
For example, the Cisco XR 12406 router features 120 Gbps switching capa city in
a 6-slot, 10-Gigabit per slot chassis. Table A-11 shows the Cisco XR 12406
Router model comparison information based on chassis slot counts, maximum
switching capacity, and switch fabric type.
On Cisco XR 12000 series routers that support switching capacity inc reases
through switch fabric upgrades, observe the following administrative
considerations after you perform the upgrade and verify 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. We recommend 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 XR software commands or the Cisco identification labels on the
switch fabric cards (SFCs and CSCs) installed in the router. Table A-11 lists
the router models and their corresponding switch fabric card identification
labels.
