• 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 that provide up to two 1000-Mbps Ethernet 
SFP GBICs; 1000BASE-SX or LX with LC-type connectors, or 
1000BASE-T with RJ-45 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 SSL Configuration Guide.
–
An additional SCM to serve as a passive redundant module.
