Powering the EX-UBT - PoE
The EX-UBT is a Power Over Ethernet device which classifies as 802.3at Class 2 (7W). Please note that there are
manufacturing and design differences between mid-span PoE injectors.
When directly connecting the EX-UBT (or any Tesira expander) to a TesiraFORTE or Tesira Server-IO AVB port, the
mid-span PoE injector must support 1 Gbps data link speed. If the mid-span PoE injector does not support 1 Gbps, the
EX-UBT power LED will illuminate steady yellow but the LED on the AVB RJ45 port will remain dark indicating no data
activity.

Troubleshooting
General
• When troubleshooting HID mute synchronization on various UC clients and hardware iterations, it is often helpful to
test and compare the mute synchronization with a wired Microsoft Teams certified headset vs. the EX-UBT.
• Be aware that UC platforms vie for the HID mute synchronization on a host machine. This means that only one can
have access to the HID communications at a time and it is common for conflict to occur if two or more UC platforms
(SFB, Teams, Zoom, Hangouts, etc.) are running at the same time on the host machine. It might be worth closing all
UC platforms before testing any HID mute synchronization.
