Chapter 1 Cisco ASR 1000 Series Routers Hardware Overview
Cisco ASR 1000 Series Routers Configurations
• One 10/100/1000-Mbps Ethernet Management port—To be used only as a management port; not to
be used as an Ethernet interface port
• Both 25-MHz and 50-MHz shared port adapter operation
• High availability software architecture
The Cisco QuantumFlow Processor processing provides:
• Architecture to address Cisco ASR 1000 Series Router performance, cost, power, and feature
velocity
• Next Generation forwarding and queuing subsystems for Cisco routers to provide data path
acceleration.
The Cisco ASR 1000 Series Router processor system performs the following system management
functions:
• Sending and receiving routing protocol updates
• Managing tables, caches, and buffers
• Monitoring interface and environmental status
• Providing Simple Network Management Protocol (SNMP) management through the console and
Telnet interface
• Accounting for and switching of data traffic
• Booting and reloading images
Cisco ASR 1000 Series Routers Configurations
The Cisco ASR 1000 Series Routers consist of a number of packaging configurations. The chassis
configurations are modular with separate field-replaceable units (FRUs) for the Cisco ASR 1000 Series
Route Processor 1 (RP1), the Cisco ASR 1000 Series Embedded Services Processor (ESP5, ESP10, and
ESP20), and the shared port adapters.
With the exception of the Cisco ASR 1002 Router, all FRUs (Cisco ASR 1000 Series Route Processor 1,
Cisco ASR 1000 Series Embedded Services Processor, and SPAs) are designed to work in the different
chassis models. (The Cisco ASR1000-ESP20 is not supported in the Cisco ASR 1002 Router.) The
power supplies and fan modules are chassis specific. The SPAs are supported in all chassis
configurations although there are SPA restrictions in the Cisco ASR 1002 Router.
Table 1-1 lists the Cisco ASR 1000 Series Routers orderable configurations.
