Proxim Tsunami MP.11 and MP.11a CPN 65755B Manual De Usuario

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. 

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.
