Note

Switch Fabric Card Cage

Caution
OL-17440-01
The lower card cage also has eight user-configurable slots that support additional
line cards, an alarm card, and an optional, redundant RP.
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.
•
This slot may be used for a line card if you are not using an redundant RP.
Note
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.
•
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.
Do not remove the blank filler panel unless instructed to do so by a Cisco support
representative.
