PoE

The MAS-A100 must be powered by a PoE class 0 equivalent power supply function
that complies with IEEE 802.3af. The MAS-A100 power consumption is 9 W (typ) and
13 W (max). When a PoE hub connects to multiple MAS-A100 units or other
PoE-compatible devices, be sure not to exceed the PoE power budget of the PoE hub.
Also, connect the frame ground of the PoE hub to the ground (Earth) connection of the
building. PoE power may not be supplied normally and the MAS-A100 may not start
due to the potential difference between the ground connection of the PoE hub
installation location and the MAS-A100 installation location.

Ethernet power-saving function

Power saving may disrupt normal operation of a Dante network. Disable power saving,
such as IEEE 802.3 Energy Efficient Ethernet (EEE) or Green Ethernet, or use a
network switch without a power saving function.

IGMP snooping

Dante networks always use multicast communication.
IGMP snooping of a network switch may disrupt Dante network communications if it is
not configured appropriately for a Dante network.
For a network that uses only unicast flows as the Dante transmission method, it is
recommended that you disable IGMP snooping. It is not recommended to use network
switches (such as TPLINK TL-SG1005P) in which IGMP snooping cannot be disabled
and cannot be configured appropriately for a Dante network.
On a network that uses multicast flows as the Dante transmission method, or that has
other multicast traffic on the same segment (same layer 2 network), IGMP snooping
may be necessary to avoid multicast flooding. In that case, select a managed switch
and configure it appropriately for a Dante network observing the following points.
