2 Cisco 12012 Gigabit Switch Router Switch Fabric Cards Replacement Instructions
Product Overview
Product Overview
The Cisco 12012 has two card cages; the upper card cage and the lower card cage. (Refer to
Figure 1.) The upper card cage has 12 user-configurable slots available for line cards and a route
processor (RP). One additional slot (rightmost slot) in the upper card cage is non-configurable; it is
reserved for an alarm card. The line cards and the RP are not slot dependent; you can install the line
cards and the RP in any of the first 12 available slots.

The lower card cage, located behind the air filter, has five horizontal keyed slots for cards containing
the switch fabric circuitry. The cards provide the physical pathway for data packet exchange between
the line cards in the upper card cage.
There are two types of cards installed in the lower card cage; the clock and scheduler card and the
switch fabric card. The clock and scheduler card is keyed for installation in either of the upper two
slots in the lower card cage. The switch fabric card is keyed for installation in the lower three slots
of the lower card cage. The cards in the lower card cage are also color-coded; the clock and scheduler
cards have a light blue label attached and the switch fabric cards have a magenta label attached. You
match the label on the card with a similar color-coded label attached to the slot in the lower card
cage.
