Control and Switching
Control and switching on the 7705 SAR-M provides the following main functions:
• node management interfaces to the 7705 SAR-M (Management (Ethernet) and
Console; see Figure 10)
• system synchronization and alarm interfaces for external inputs and outputs (see
Figure 10)
• routing, switching, and services functions for the entire system
Each variant of the 7705 SAR-M chassis is shipped with a 256 Mbyte compact flash memory
device that stores system boot software, OS software, and configuration files and logs. The
compact flash device is accessible via an access cover that is positioned on the left side of the
rear chassis plate. Accessing the compact flash device facilitates the commissioning process
as the device can be installed pre-programmed with the desired software and configuration
files.
