The Cisco FM4200 Fiber can be provided with power using the following
methods:
• A standard
(for example, from a compatible network switch).
• A compatible 48 Vdc passive PoE injector conforming to either
IEEE 802.3af
• A 48 Vdc power source equipped with an M12A connector.
When providing the power source for the Cisco FM4200 Fiber, remember
the following important points:
• Install the power source as close to the unit as possible to minimize
voltage drop. The maximum suggested distance is 165ft (50m).

DC IN, LAN and fiber-optic ports
The Cisco FM4200 Fiber radio transceiver unit has three connector ports
(Figure 7 (page
Figure 7. Device connector ports
• The DC IN connection is a 5-pin M12A port, exclusively designed to
accept passive 48 Vdc power.
• The LAN connection is an 8-pin M12X port, designed to connect
the unit to a local area network (LAN) switch and/or to an IEEE
802.3 48 Vdc power source.
• The SFP connection is a small form-factor pluggable (SFP) port,
exclusively designed to connect the unit to a duplex fiber-optic data
link.
