A Session Accelerator module (SAM) 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 system for port density and performance.The Session Accelerator Module (SAM), model CSS5-SAM, is used with the SCM to provide additional processing support for session setup. The SAM front panel LEDs indicate its operational status. The SAM has no connectors.
