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. |
