Cisco ASR 1000 Series Routers Components

The Cisco ASR 1000 Series Routers contain the following components:

• Cisco ASR 1000 Series Route Processor, page 2-1

• Cisco ASR 1000 Series Embedded Services Processors, page 2-9

• Cisco ASR 1000 Series SPA Interface Processor, page 2-13

• Cisco ASR 1000 Series Router Power Supplies, page 2-16

Note Throughout this document, the term slot refers to a Cisco ASR 1000 Series Router chassis slot. The

Cisco ASR 1000 Series Route Processor 1, Cisco ASR 1000 Series Embedd ed Services Processor, and

Cisco ASR 1000 Series SPA Interface Processor (SIP), and power supplies plug into these slots. Shared

port adapters plug into SIP bays.

Cisco ASR 1000 Series Route Processor

The Cisco ASR 1000 Series Route processor is the central network clocking card and runs the network

operating system, BINOS kernel plus IOSD (IOS daemon). The Cisco A SR1000-RP1 is responsible for:

• Selection of the active Cisco ASR 1000 Series Route Processor and the Cisco ASR 1000 Series

Embedded Services Processor and notification of the Cisco ASR 1000 Serie s SPA Interface

Processor of these events.

• All the control processors communicating and performing packet processing on packets punted to it

by the Cisco ASR 1000 Series Embedded Services Processors (ESP).

The Cisco ASR 1000-RP1 has LED status indicators, an RJ-45 plug for DTI and BITS timing re ference,

and two USB ports which can be used with smart cards for secu re key distribution.

Specific system tasks performed by the Cisco ASR 1000 Series Route Processor include the following:

• Runs the router control plane, including network control packets, and connection setup

• User interfaces: 10/100/1000 Management Ethernet, CON/ AUX, USB

• Active and standby Cisco ASR 1000 Series RP1 and Cisco ASR 1000 Series Embedded Services

Processor master and standby synchronization (Tasks include switchover from failing master to

standby.)

• Code storage, management, and upgrade.
