Upper and Lower Cable Management Brackets
The Cisco XR 12416 router includes upper and lower cable management brackets
that work together with individual line card cable management brackets to
organize interface cables entering and exiting the router (see
Figure 1-1 ).
Network interface cables to the line cards are fed across the brackets, and then
through the openings to the individual line card cable management bracket. This
system keeps cables out of the way and free of sharp bends.
Caution Excessive bending of interface cables can damage the cables.
Upgrading a Cisco 12000 Series Router to a
Cisco XR 12000 Series Router
A Cisco 12410 Router can be upgraded to a Cisco XR 12410 and Cisco XR 12810
Routers by updating the line cards and software images. For information on this
process, including supported line cards and software upgrade procedures, please
refer to the Cisco document, Upgrading a Cisco 12000 Series Router from Cisco
IOS Software to Cisco IOS XR Software.
The line card and route processor (RP) card cage has 10 user-configurable slots
that support a combination of line cards and either one or two RPs (see
Figure 1-2 ). Router configurations can consist of either nine line cards and one
RP, or eight line cards and two RPs (one primary and one redundant) using the
following slot configurations:
• Slots 0 to 7 accommodate the newer (wider) line card designs. These wider
line card slots can also accept narrower legacy line cards.
• Slots 8 and 9 only accept RPs or a narrower legacy line card.
Note If a system uses only one RP install it in slot 9. You can use slot 8 for a
legacy line card.
