For modular MSR series routers, a wide range of optional flexible interface
cards/double flexible interface cards (FICs/DFICs) are available, which provide
abundant interfaces, such as synchronous/asynchronous serial interface, Ethernet
interface, E1/T1, ISDN BRI/PRI, audio interface, Layer 2 switching interface, and so
on.

Among this series interface cards, the Layer 2 switching interface cards
(FIC-16FSW and DFIC-24FSW) each have a corresponding PoE-capable one, which
can provide -48 VDC power to remote PDs (such as IP phone, WLAN AP, and
network camera) through straight-through network cables as long as installed on
a PoE router.

Introduction
The 1-port, 2-port, and 4-port 10Base-T/100Base-TX fast Ethernet interface cards
(FIC-1FE, FIC-2FE, and FIC-4FE) are mainly used for the communication between
router and LAN.

The cards support:
■
100 meters (328.1 ft.) of transmission segment over the category-5
twisted-pair cable.
twisted-pair cable.
■
Operation at 100 Mbps and 10 Mbps, autosensing.
■
Full duplex and half-duplex, with the former in common use.
