SIC/DSIC
MSR series routers use modular design and support a wide range of SICs and DSICs. A SIC
occupies one SIC slot and a DSIC occupies two SIC slots. The SIC/DSIC series interface modules
provide interfaces such as synchronous/asynchronous serial interface, Ethernet interface, E1/T1,
ISDN BRI/PRI, ADSL, audio interface, and Layer 2 switching interface.
Among this series interface modules, the Layer 2 switching interface modules (SIC-4FSW and
DSIC-9FSW) each have a corresponding PoE-capable module. The module can provide -48 VDC
power to remote powered devices (PDs, such as IP phone, WLAN AP, network camera) through
straight-through cables if it is installed in a PoE router.

Introduction
The 4/9-port 10/100 Mbps Ethernet Layer 2 interface modules SIC-4FSW/SIC-4FSW-PoE and
DSIC-9FSW/DSIC-9FSW-PoE can provide up to 4/9 10/100 Base-Tx Ethernet ports for Layer 2 and
Layer 3 switching. A router installed with SIC-4FSW/DSIC-9FSW modules can work as a
switching/routing integrated device on a small-sized enterprise network to connect PCs and network
devices inside the network. The SIC-4FSW-PoE/DSIC-9FSW-PoE interface modules can supply
power to powered devices (PDs) through power over Ethernet (PoE).
