  • Page 2: Product Description

    Product Description These two router models are differentiated by the switching capacity of the switch fabric installed in the router: Cisco 12006 Router—2.5-Gbps switch fabric • Cisco 12406 Router—10-Gbps switch fabric • Other than their various capacities, these routers are almost identical. Differences between each router are described unless otherwise noted, all information in this publication applies to all routers.

  • Page 11 Chapter 1 Product Overview System clock—The system clock synchronizes data transfers between line • cards or between the RP and a line card, through the switch fabric. In systems with redundant CSCs, the two system clocks are synchronized so that if one system clock fails, the other clock takes over.

  • Page 12: Switch Fabric Redundancy

    Multigigabit Crossbar Switch Fabric Switch Fabric Switching Capacity and Router Type The Cisco 12006 Router is based on a 2.5-Gbps switch fabric, where each CSC or SFC provides a 2.5-Gbps full-duplex connection to each line card in the system. The 2.5-Gbps switch fabric consists of the 12006 Advanced Clock and Scheduler Card (product number 12006-CSC=) and the 12006 Advanced Switch Fabric Card (product number 12006-SFC=).

    Chapter 1 Product Overview Maintenance Bus The Cisco 12006 and Cisco 12406 router maintenance bus and MBus modules manage the maintenance functions of the system. The MBus is integrated into the backplane and consists of two separate buses, providing MBus redundancy. Both MBus networks are linked to all the following items: Route processor and line cards •...

  • Page 14: Code Download

    Maintenance Bus Code Download A portion of the line card operating software can be downloaded from the RP to the line card over the MBus. Because the MBus is relatively slow compared to the switch fabric, only enough code is downloaded to the line card for it to access the switch fabric and complete the download process.

  • Page 47: Power Distribution

    Chapter 1 Product Overview Power Distribution The router chassis backplane distributes -48 VDC power throughout the router and to all cards in the card cages. All cards have multiple DC-DC converters that convert the -48 VDC into +2.5 VDC, +3.3 VDC, +5 VDC, and other voltages as required by the line card. The DC-DC converters are turned on by the MBus modules under the control of the RP and MBus software.
