Introduction
SIC-4FSW/SIC-4FSW-PoE and DSIC-9FSW/DSIC-9FSW-PoE interface cards are
4/9-port 10/100 Mbps Ethernet Layer 2 SIC interface cards that can be used on
H3C MSR 20/30/50 series routers. They 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
