• Download the Omada Discovery Utility and run it on PC2 at the branch office.

• Router B, the Omada switch, and EAP Access Point will be discovered by Utility automatically. Click the "Select All" and "Batch Setting" buttons in the lower right corner.

• Fill out the fields, the Center IP is Router A's WAN IP, in this example: 192.168.1.200. Then click Apply.

*Note: The factory default username and password of TP-Link devices are admin/admin.  If you have already configured these devices in standalone mode and changed their username and password, you can manage them by entering their username and password separately. 

• The devices will appear in the devices list with "PENDING" status, then you can adopt and manage them.

For Router B:

• Go to System Tools > Controller Settings > Inform URL/IP Address, input the Router A WAN IP in the box and click Save.  In this example 192.18.1.200. Then Router B can find the Controller.

For Switch:

• Go to System Tools > Controller Settings > Inform URL/IP Address, input the Router A WAN IP in the box and click Apply.  In this example 192.18.1. 200.

For EAP:

• Go to System Tools > Controller Settings > Inform URL/IP Address, input the Router A WAN IP in the box and click Save.

• After informing the devices of the Controller IP, the devices will appear in the Controller Device list with the "PENDING" status, then you can adopt them.

Note: Currently, this method is only suitable for Omada Switches and EAPs.

For Switches:

• Access its management page, then go to SECURITY > Access Security > SSH Config > enabled SSH under Global Config on the switch management page, then click Apply,
