CloudEngine S12700E 03033EMG 48-port S12700E Series router Line Cards LST7SFUEX100 The LST7SFUEX100 provides the data plane for the entire system. The data plane provides high-speed, non-blocking data channels for data switching between service modules. The LST7SFUEX100 consists of the following functional modules: Switching module: functions as the data plane and provides high-speed service channels for data switching. Local clock module: provides the working clock for the chips of the switching module, management module, and monitoring module on the LST7SFUEX100. Power supply module: provides power supply for the LST7SFUEX100. Function Description Basic function Core of data switching in the S12700E-4 and S12700E-8 system. Memory 1 GB Flash 128 MB Redundancy backup N+1 hot standby LST7SFUEX100 cards in a chassis work in redundancy mode to improve system reliability. If one SFU fails, service traffic on this card will be switched to other SFUs to ensure uninterrupted services. Hot swapping Supported NAND Flash 2 GB The system configuration data, startup files, system software package, and system logs are saved in the NAND Flash by default. Redundancy backup 1+1 hot standby Main control board is mandatory for switches. Each switch must be configured with one or two main control boards. When one main control board is configured for a switch, the main control board can be installed in either main control board slot of the switch. When two main control boards are configured, the two main control boards work in hot standby mode to improve reliability of the switch. The active and standby main control boards monitor the status of each other. If the active main control board fails, the standby main control board automatically becomes active to ensure uninterrupted services. Hot swapping Supported Before removing a running SFU, hold down the OFL button on the SFU until the OFL indicator turns red.
