Supporting Modules

Cisco 12000/10720 Router Manager supports five types of supporting modules within a Cisco 12000
Series Router chassis. Some modules only apply to certain chassis types.

Physical Interfaces and Technologies

Physical interfaces are modeled as objects below the parent line card. Some generic properties are
supported by all the interfaces. As mentioned before, the type of line card characterizes the type of
physical interface; for example, an ATM line card will only support ATM interfaces. However, there can
be multiple technologies supported on that physical interface. For example, ATM physical interfaces can
support the following:
•

Note Cisco 12000/10720 Router Manager handles both SDH and SONET in the same manner.
The Cisco 12000/10720 Routers support both SDH and SONET. For a comparison chart of
SONET and SDH speeds, see

Lower card cage, which contains the following:
1 Non-configurable alarm card in far right slot
–
1 Optional GRP in far left slot
–
Up to 8 line cards

CSC (Clock Scheduler Card)—CSCs handle requests from line cards, issue grants to access the
switch fabric cards, and provide a reference clock to all the cards in the system to synchronize data
transfer across the crossbar. Each chassis must have at least one CSC.
SFC (Switch Fabric Card)—SFCs receive the scheduling information and clocking reference from
the CSC cards and perform the switching functions.
AC or DC Power Supply Module—Chassis can be ordered with either AC or DC power supply
modules, having anywhere from one to four AC or DC-input power supplies, depending upon the
specific chassis.
Blower Module—The Cisco 12012 and 12016 Routers contain two blower modules, which circulate
cooling air through the card cages in the chassis.
Fan Tray—The Cisco 12008 Router contains a fan tray, which circulates cooling air through the card
cage in the chassis.
