5700系列交換機目前暫無reset按鍵，清空配置的方法如下：
1.系統視圖下輸入
[S5348TP-SI]undo startup saved-configuration
取消下次啟動時已保存的配置啟動
2.用戶視圖下輸入
reset saved-configuration
Warning: The action will delete the saved configuration in the device.
The configuration will be erased to reconfigure. Continue? [Y/N]:Y
清除保存的配置，系統會提示是否刪除，選擇Y
3.用戶視圖下輸入
reboot
Info: The system is now comparing the configuration, please wait.
Warning: All the configuration will be saved to the configuration file for the next startup:, Continue?[Y/N]:N
Info: If want to reboot with saving diagnostic information, input 'N' and then execute 'reboot save diagnostic-information'.

重啟設備，此時系統會提示兩次選擇，第一次提示是否保存當前配置，選擇N，第二次提示是否重啟，選擇Y。
重啟完成后設備即恢復出廠設置。
