An engineer is deploying a Cisco TelePresence Touch 8 controller for a Cisco TelePresence SX20. Which step is required as part of this process?

The Cisco TelePresence Touch 8 receives power from a dedicated power adapter and connects to the network via Ethernet, where the SX20 discovers it automatically using an IP-based pairing process. This network-based connection model is the standard deployment method for the Touch 8 - it does not require a direct proprietary cable between the controller and the SX20 codec. Connecting power and network is the essential prerequisite before pairing can occur.

There is no valid factory reset or pairing procedure for the Touch 8 that involves holding the mute button for 20 seconds during power-on.

The Touch 8 controller pairs with the SX20 over the network via IP, not through a direct physical cable between the two devices.

Rebooting the SX20 is not a required step in the Touch 8 deployment process - pairing is initiated after the Touch 8 has network connectivity.
