An engineer is deploying a Cisco TelePresence Touch 8 controller for a Cisco TelePresence SX20. Which two steps are required as part of this process? (Choose two.)

The Touch 8 does not use a direct proprietary cable to the SX20; it communicates with the codec over the IP network, so no direct physical link between the two devices is needed.

The Touch 8 receives power via Power over Ethernet (PoE) from a network switch, so connecting it to a PoE-capable network port is the primary physical setup step required before the device can communicate with the SX20.

The Touch 8 is not connected to a secondary network adapter on the SX20 itself; it connects independently to the LAN switch and discovers the SX20 over the network.

After the Touch 8 is connected to the same network as the SX20, the SX20 must be rebooted so the codec can discover and pair with the Touch 8 controller via its IP-based pairing mechanism.

Holding the mute button for 20 seconds during power-on is not a documented initialization or factory-reset procedure for the Touch 8 controller.
