S12700 SFU clustering


The S12700 uses a hardware architecture that separates the switching plane from the control plane. It has independent SFUs, and the CSS card is installed on the SFU. Packet forwarding is not affected when the S12700 has no MPU installed. This architecture allows two S12700s to set up a CSS with no MPU installed on the standby switch. 1+N backup of MPUs enables a CSS to run stably as long as one MPU of any chassis in the CSS is working normally.

SFU functions of S12700 switches
The ET1D2SFU 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 ET1D2SFU 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 ET1D2SFU. - Power module: provides power supply for the ET1D2SFU.

What is the temperature of the S12700 in different situations
The temperature range of the S12700 is as follows: Operating temperature: 0°C to 45°C Storage temperature: -40°C to +70°C You can run the display temperature command to view the temperature of the S12700 card. If no alarm is generated, the device is working normally and the temperature is within the allowed range. NOTE: The set transceiver temperature threshold command sets the temperature threshold for adjusting the fan speed. When the temperature of an optical module exceeds the upper threshold, the fan speed is increased. When the temperature of an optical module falls below the lower threshold, the fan speed is reduced. The display transceiver temperature threshold command displays the upper and lower temperature thresholds for adjusting the fan speed.
