Manually Pair the Poly TC8 with a Video System

You can manually pair the Poly TC8 connected to your primary network with a video system in the room.
To pair, the Poly TC8 must be on the same subnet as the video system and the following network components unblocked:

• Multicast address 224.0.0.200
• UDP port 2000
• TCP port 18888

You may see multiple devices that you can pair with on your video system's Device Management page. Know the MAC address to ensure you're pairing with the device you want such as the device in the room you're setting up.
A device may pair automatically after connecting to the network. However, you may need to manually pair a device in the following situations:

• The device doesn't automatically pair during setup with the system that you purchased.
• You want to pair the device with a different system.
• You want to pair additional devices to control the video system with more than one TC8.

1. Connect the Poly TC8 that you want to pair to an Ethernet port in the room.
2. In the system web interface, go to General Settings > Device Management.
3. Under Available Devices, find the device by its MAC address such as 00e0db4cf0be and select Pair.
   If paired successfully, the device displays under Connected Devices with a Connected status. If a device shows a Disconnected status, the pairing wasn't successful.

If pairing isn't successful, check the network connection and the configuration of both the Poly TC8 and the system you want to pair it with.

SCEP support on Poly touch controllers

You can manage certificates using your touch controller.
SCEP enables you to automatically enroll devices to retrieve new digital certificates or renew expiring certificates. If paired, your touch controller syncs settings automatically from your Poly video system.
Configure or pair the touch controller in a staged network before moving to an 802.1x enabled network.

• Settings can't be configured via the touch controller. SCEP and 802.1x settings are read-only.
• The touch controller syncs all SCEP and 802.1x settings from the primary device.
• Settings can either be set in the system web interface or provisioned via Poly Lens.

NOTE: Only HTTP SCEP server URLs are currently supported. Your SCEP challenge password must be configured as a static password. A single set of credentials is shared between the Poly video system and the Poly touch controller.

Enable 3K-bit encryption

A 3072-bit encryption certificate is a more secure type of digital security key compared to shorter 2048-bit keys, ensuring better security for sensitive information. The 3072-bit certificate identifies the device for network access such as 802.1x, Simple Certificate Enrollment Protocol (SCEP), and web proxy.
Note the following information about provisioning:

• A paired touch controller inherits the encryption bit length from the paired Poly video conferencing system, which is configured in the video conferencing system web interface.
• You can provision 3072-bit certification for all devices via SCEP in Poly Lens. When your 2048-bit certificates expire, the SCEP server sends 3072-bit certificates.
• For those not using Poly Lens, configure via the touch controller web interface. Delete the 2048-bit certificate, and set the certificate key size to 3072. Depending on network settings this may result in a loss of device connection. Re-pair the device on your staging network.

Restrict view of information screen in touch controller interface to administrators
