ASR 5000 Hardware Platform Overview

ASR 5000 Application Cards

The following application cards are supported by the system.

System Management Card

The System Management Card (SMC) is used with packet processing cards in the ASR 5000 hardware platform. The
SMC serves as the primary controller, initializing the entire system and loading the software's configuration image into
other cards in the chassis as applicable.
SMCs are installed in the chassis slots 8 and 9. During normal operation, the SMC in slot 8 serves as the primary card
and the SMC in slot 9 serves as the secondary. Each SMC has a dual-core central processing unit (CPU) and 4 GB of
random access memory (RAM).
There is a single PC-card slot on the SMC that supports removable ATA Type I or Type II PCMCIA cards for
temporary storage. Use these cards to load and store configuration data, software updates, buffer accounting
information, and store diagnostic or troubleshooting information.
There is also a type II CompactFlash™ slot on the SMC that hosts configuration files, software images, and the session
limiting/feature use license keys for the system.
The SMC provides the following major functions:
Non-blocking low latency inter-card communication
1:1 or 1:N redundancy for hardware and software resources
System management control
Persistent storage via CompactFlash and PCMCIA cards (for field serviceability), and a hard disk drive for
greater storage capabilities
Internal gigabit Ethernet switch fabrics for management and control plane communication
