Cisco ASR 1000 Series Routers Components
The Cisco ASR 1000 Series Routers contain the following components:
• Cisco ASR 1000 Series Route Processor 1, page 2-1
• Cisco ASR 1000 Series Embedded Services Processor, page 2-8
• Cisco ASR 1000 Series SPA Interface Processor, page 2-10
• Cisco ASR 1000 Series Router Power Supplies, page 2-14
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 Embedded Services Processor, and
Cisco ASR 1000 Series SPA Interface Processor, and power supplies plug into these slots. SPAs plug
into SIP bays.
Cisco ASR 1000 Series Route Processor 1
The Cisco ASR 1000 Series Route Processor 1 (RP1) is the central network clocking card and is
responsible for:
• Cisco ASR 1000 Series Routers field-replaceable unit (FRU) online insertion and removal (OIR).
• Selection of the active Cisco ASR 1000 Series Route Processor 1 and the Cisco ASR 1000 Series
Embedded Services Processor and notification of the Cisco ASR 1000 Series 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 Processor (ESP).
Specific system tasks performed by the Cisco ASR 1000 Series Route Processor 1including 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 Route Processor 1 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
