IP Device Can’t Pair to the Video System
If your device can’t pair to the video conferencing system, use the following information to
troubleshoot the issue.
Symptom
● After powering on the Poly TC8 device, it doesn’t automatically pair with the video system.
● You can’t manually pair the device from the Available Devices list in the video system web
interface.
Problem
There are a few possible causes for this issue:
● Network traffic on TCP port 18888 is blocked.
● Your system and Poly TC8 aren't on the same VLAN.
Workaround
Complete each step until the device pairs with your system:
1. Allow traffic on TCP port 18888.
2. On your Poly TC8 device, verify that the Poly TC8 VLAN ID matches the VLAN ID on your
system.
IP Device Doesn’t Display on the Available Devices List
The Poly TC8 device you want to pair is connected to the network but you don’t see it under Available
Devices in the video system web interface.
Problem
There are a few possible causes for this issue:
● The device and video system aren’t on the same subnet.
● The network switch isn’t allowing UDP broadcast traffic forwarded to multicast address
224.0.0.200 on port 2000.
● The device is paired with another video system.
Workaround
Complete each step until you see the Poly TC8 device on the Available Devices list:
1. Make sure the device and video system are on the same subnet.
If needed, work with your network administrator.
2. Allow traffic to 224.0.0.200 on UDP port 2000.
3. Make sure the device isn’t paired with another video system. If it is, unpair the device.
4. Go to Settings > Reset and select Reset.
Your device resets to its default configuration settings, which unpairs it from the video system.
