Does the GE optical LPU of the S7700&S9700 support 100M optical module
The S7700&S9700's GE optical LPU supports both 100M optical modules and 1000M optical modules. When a 100M optical module is used, you must run the speed 100 command on the interface to set the interface rate to 100 Mbit/s. When using a GE optical module, an interface works at 1000 Mbit/s by default. If auto-negotiation is enabled on the interface, the interface speed cannot be set to 100 Mbit/s. If auto-negotiation is disabled, you can run the speed 100 command to set the interface speed to 100 Mbit/s. The 100M optical interface can only use the 100M optical module, and the default interface rate is 100M. When two optical interfaces are interconnected, they must use the same type of optical module.

Does the S7700&S9700 support hot backup
The S7700&S9700 supports hot backup. When the master main control board fails, the S7700&S9700 automatically switches services to the slave board without interrupting the services. The software versions of the master board and slave board must be the same. You can also run the slave switchover command to trigger the active/standby switchover manually. [HUAWEI] slave switchover Caution!!! Confirm switch slave to master[Y/N]?y Ensure that data on the master board is backed up to the slave board before you trigger the master/slave switchover. That is, the slave board is in the real-time backup state. If the board is backing up data, you cannot perform switchover. In this case, you can run the display switch state command to view the status of the slave board. display switch state Master MPU: Realtime and routine backup. Slave MPU: Receiving realtime and routine data.

Does the S7700&S9700 support the adjustment of fan speed
The S7700&S9700 series switches support the adjustment of fan speed. The speed of operating fans can be automatically adjusted based on the temperature inside the chassis. In addition, you can also manually change the fan speed using the set fan-speed command. You can run the display fan command to check the status of fans.
