This topic describes how to view the WAN + 4G backup of a Smart Access Gateway (SAG). By default, WAN + 4G backup is enabled for SAG-100WM and SAG-1000 to use wired broadband as the active link and wireless 4G-LTE as the standby link. If the active link fails, the system automatically switches to the standby link.


  1. Log on to the Smart Access Gateway console.
  2. In the left-side navigation pane, clickSmart Access Gateway, and then click the instance ID of the SAG for which you want to perform an active/standby switchover.
  3. In the left-side navigation pane of the SAG details page, click HA Configuration.
  4. On the HA Configuration page, view the current active and standby links of the SAG in the WAN + 4G area.
    The HA structure of SAG-100WM and SAG-1000 is displayed, as shown in the following figure.
