6. RESET button

NOTE:
This button is used to reset the router.
  • In an empty configuration scenario, ensure that the router has no console port input, and has no user login routers. If the Reset button is pressed and held for at least 5 seconds, you will access the registration query center of Huawei devices and obtain the cloud management platform address of routers for plug-and-play deployment.
  • In the configured scenario, hold down the button for at least 5 seconds to restore the factory settings.
  • To reset the router, hold down the button for less than 5 seconds.
Resetting the router will interrupt services. Exercise caution when deciding to press this button.

If needed, you can run the factory-configuration prohibit command in the system view to disable the function of restoring the factory settings by holding down the RESET button. To enable this function again, run the undo factory-configuration prohibit command.

7. One console interface

8. LAN interfaces: eight GE electrical interfaces

9. WAN interfaces: two GE electrical interfaces

10. WAN interfaces: 2 x 10GE optical interfaces

11. Power socket

12. Jack for power cable locking strap

NOTE:

Insert a power cable locking strap in this jack to secure the power cable.
