Please refrain from daisy-chaining the devices. Currently, the ProAudio devices only support a star topology connection.

No. EEE (Energy Efficient Ethernet) is designed to decrease switch power consumption during low network traffic.

However, some switches do not perform the power negotiation properly or automatically. This may lead to unintended EEE activation in Yealink networks, resulting in synchronization issues and occasional dropouts. Therefore we strongly recommend that:

• For unmanaged switches, use switches without the EEE feature as you cannot disable the EEE feature in these switches.

• For managed switches, use switches that allow the EEE to be disabled and ensure that the EEE is disabled on all ports used for real-time traffic.

You can use the following types of switches:

The table below lists the power consumption of CM20 and CS10.

Here is the consumption of AVHub:
Noted: Each VCH port of RCH40 E2 Support PoE+ power supply (30W PSE with 25.5 power supply)

Here is the consumption of RCH40 E2:
Noted: Each port (except Uplink port) of RCH40 E2 Support PoE+ power supply (30W PSE with 25.5 power supply)

If you want to directly connect Yealink ProAudio devices to the host device using an Ethernet cable, you can use either RCH40 E2 or AVHub to connect to the host device.

• For a single RCH40 E2, it supports 2 speakers + 2 microphones, and it is not recommended to connect more than 3 speakers (which require RCH40 E2 to provide 24W for each port connected with CS10) simultaneously to avoid the risk of insufficient power.

• For a single AVHub, it supports 2 CS10 + 2 CM20, and it is not recommended to connect more than 3 speakers (which require AVHub to provide 24W for each port connected with CS10) simultaneously to avoid the risk of insufficient power.

The above table is only applicable to CM20 and CS10. The CS10-Dante version is not compatible with the above hosts.
