Cisco Systems 11500 Series Switch Module SM. An SM provides connectivity among the SCM and IOMs

Chapter 2 Cabling and Troubleshooting the CSS

Cabling the CSS 11503 and CSS 11506 Modules

•Switch Module (SM). An SM provides connectivity among the SCM and IOMs.

–The CSS 11503 has a single integrated SM. A single SM has an aggregate throughput of 20 Gbps.

–The CSS 11506 has two removable SMs that share the switching functions. Two SMs provide 40 Gbps aggregate throughput. As implemented in WebNS 5.10 and greater, if one SM fails, the CSS reboots and continues to operate through the other SM.

•Two slots in the CSS 11503 and five slots in the CSS 11506 are configurable with:

–Fast Ethernet Modules that provide either 8 or 16 auto-sensing 10/100-Mbps Ethernet (10BASE-T/100BASE-TX) RJ-45 ports.

–Gigabit Ethernet Modules provides up to two 1000-Mbps Ethernet (1000BASE-SX or LX) SFP GBICs with LC-type connectors.

–A Session Accelerator Module (SAM) that provides a cost-effective way to add flow performance when additional connectivity is not required. Using the same flow setup and forwarding processors as the I/O modules, it provides the flexibility to optimize the CSS for port density and performance.

–A Secure Socket Layer (SSL) module that functions as an SSL server by adding security services between the Web browsers (the client) and HTTP servers and backend SSL servers. The SSL module is responsible for all user authentication, public/private key generation, certificate management, and packet encryption and decryption functions between the client and the server. Each SSL module terminates SSL connections received from a client. The CSS 11503 supports a maximum of two SSL modules and the CSS 11506 supports a maximum of four SSL modules. For information on SSL commands and functions, refer to the Cisco Content Services Switch Advanced Configuration Guide.

–An additional SCM to serve as a passive redundant module.
