I/O Modules for the Cisco CSS 11500 Content Services Switch
The Cisco CSS 11500 I/O modules deliver port density and flow performance. The product line supports three types
of I/O modules:
• Two-port Gigabit Ethernet
• Sixteen-port Fast Ethernet
• Eight-port Fast Ethernet
The Fast Ethernet ports are 10/100BASE-TX with standard RJ-45 connectors, whereas the Gigabit Ethernet ports
require small-form factor GBICs (1000BASE-SX or 1000BASE-LX).
Session Accelerator Module for the Cisco CSS 11500 Content Services Switch
The session accelerator module is 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 system for port density and performance. Table 1 gives the features of the Cisco CSS 11500 models.
