請問大家，小弟該如何做，才能重新 進去 Switch> 模式呢 ?

Switch # factory-reset all
The factory reset operation is irreversible for all operations. Are you sure? [confirm]y
The following will be deleted as a part of factory reset:
1: Crash info and logs
2: User data, startup and running configuration
3: All IOS images, including the current boot image
4: OBFL logs
5: User added rommon variables
6: Data on Field Replaceable Units(USB/SSD/SATA)
The system will reload to perform factory reset.
It will take some time to complete and bring it to rommon.
You will need to load IOS image using USB/TFTP from rommon after
this operation is completed.
DO NOT UNPLUG THE POWER OR INTERRUPT THE OPERATION
Are you sure you want to continue? [confirm]y
Successfully removed non factory default boot variables in rommon
