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
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
• Internal gigabit Ethernet switch fabrics for management and control plane communication
