Cisco Systems Cisco XR 12416 manual Lower Card Cage, Switch Fabric Card Cage

Chapter 1 Product Overview

Chassis Card Cages

Lower Card Cage

The lower card cage also has eight user-configurable slots that support additional line cards, an alarm card, and an optional, redundant RP.

Note The lower card cage is an inverted, or head-down,copy of the upper card cage, which means that cards are installed in an inverted or head-down orientation. The orientation of the slots is opposite that of the upper card cage.

•Slot 8—The far left slot is reserved for an optional redundant RP.

Note This slot may be used for a line card if you are not using an redundant RP.

•Slots 9 through 15—Can be populated with any line cards supported by the router.

•Alarm—The far right slot is a dedicated slot for an alarm card.

Switch Fabric Card Cage

The router ships from the factory with 2 CSCs and 3 SFCs installed in five of the eight slots in the switch fabric card cage.

•The 2 CSCs are installed in slot 0 (CSC0) or slot 1 (CSC1)

•The 3 SFCs are installed in slot 2 (SFC0), slot 3 (SFC1), and slot 4 (SFC2).

•Three non-working slots with no backplane connectors. These non-working slots are not labeled, but there is a blank filler panel installed in the far left slot to help maintain proper air flow through the chassis.

Caution Do not remove the blank filler panel unless instructed to do so by a Cisco support representative.
