If you choose the standby mode when you purchase a device, you can quickly switch to the standby device when the active device fails.


  • Make sure that you select the Active/Standby mode when purchasing the device.

  • Make sure the device configurations are the same for both devices.


  1. Log on to the Smart Access Gateway console.
  2. On the SAG page, find the target instance and click the ID of the instance.
  3. In the High-Availability Configurations area, click the Switch option of the standby gateway device.

    Note For SAG-100WM Smart Access Gateway devices, after you switch to the standby device on the console, you must also connect the WAN port of the on-premises gateway device to the Internet.
