4.8.2. Avoid Causing an Ethernet Loop
A TPS board (actually the Ethernet switch of the board) can be uplinked to the same LAN only once to avoid
an Ethernet loop. In this case, if the other network devices are not able to handle Ethernet loops, the LAN
network may break down.
Example
The TPS board connects first to the router of the ROOM 1 via the switch of the ROOM 2. The HDMI-TPS-TX95
in the ROOM 3 is connected to the LAN via TPS link. If the installer does not know the transmitter has already
connected to the LAN via TPS and links the transmitter to the switch – shown by the brown arrow in the
picture – it results in an Ethernet loop – demonstrated by the red lines on the picture below.
