Tsunami MP.11and MP.11a Installation and Management
Point-to-Multipoint Network
If you want to connect more than two buildings, you can set up a single Point-to-Multipoint network with
a single Base interface and multiple Satellite interfaces, as depicted in the following figure.
In this figure, the system is designed as follows:
▪ The central building B is equipped with a Base interface, connected to either an omni-directional, or
a wide angle antenna.
▪ The two other buildings A and C are both equipped with a Satellite interface connected to a
directional antenna.
ACTIVE ETHERNET The MP.11/a is equipped with an 802.3af-compliant Active Ethernet module. Active Ethernet delivers
both data and power to the radio over a single Ethernet cable. If you choose to use Active Ethernet,
there is no difference in operation; the only difference is the power source.
▪ The Active Ethernet integrated module receives –48 VDC over a standard Cat 5 Ethernet cable.
▪ To use Active Ethernet, you must have an Active Ethernet hub (also known as a power injector)
connected to the network. The Active Ethernet hub is not a repeater and does not amplify the
Ethernet data signal.
▪ The cable length between the Active Ethernet hub and the radio should not exceed 100 meters
(approximately 325 feet).
▪ If connected to an Active Ethernet hub and an AC power supply simultaneously, the radio draws
power from Active Ethernet.
▪ Maximum power supplied to an MP.11 is 11 Watts; maximum power supplied to an MP.11a is 36
Watts. The units typically draw less than 7.5 Watts.
