Image to Upgrade Field-Programmable Hardware Devices
Starting in Cisco IOS XE Release 3.1S, an independent image used to upgrade field programmable hardware
devices is released periodically, separate from the consolidated packages. An image is provided for the field
programmable device to customers in cases where a field upgrade is required. If the Cisco ASR 1000 Series
Router contains an earlier released version of the hardware programmable firmware on the Cisco ASR1000-RP,
Cisco ASR1000-SIP, or Cisco ASR 1000-ESP, then that hardware programmable firmware may need to be
upgraded.
Generally an upgrade is only necessary in cases where a system message indicates one of the field programmable
devices on the Cisco ASR 1000 Series Routers needs an upgrade or a Cisco technical support representative
suggests an upgrade.
For example, in Cisco IOS XE Release 3.1S, a hardware (hw)-programmable upgrade package file image that
contains a new version of the Complex Programmable Logic Device (CPLD) code is available for users who
need to update prior released Cisco ASR1000-RP2 and Cisco ASR1000-SIP10 modules in the Cisco ASR
1013 Router.

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 ASR1000-RP1 and Cisco ASR1000-RP2 are
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 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 Processors.
The Cisco ASR 1000-RP1 and Cisco ASR1000-RP2 have LED status indicators, an RJ-45 plug for DTI and
BITS timing reference, and two USB ports which can be used with smart cards for secure key distribution.
Specific system tasks performed by the Cisco ASR 1000 Series Route Processors include the following:
•
Runs the router control plane, including network control packets, and connection setup
•
Supports single-bit error correction and multi-bit error detection
•
User interfaces: 10/100/1000 Mbps Management Ethernet, CON/AUX, USB
•
Active and standby ASR1000-RP1, ASR1000-RP2, 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.
•
Supports on-board failure logging (OBFL) with 2 MB of memory.
•
Downloading operational code for SIPs and Cisco ASR 1000 Series Embedded Services Processor over
Ethernet out of band channel (EOBC), which is used for communication between the control processors
on the Cisco ASR 1000 Series Routers
