Application Cards; System Management Card (Smc) - Cisco ASR 5000 Series Installation Manual

ASR 5000 Hardware Platform Overview

Application Cards

The following application cards are supported by the system.

System Management Card (SMC)

The SMC serves as the primary system 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 front panel of the SMC that supports removable ATA Type I or Type II PCMCIA
cards. 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
The front panel of the SMC with its major components is shown below:
