SIC/DSIC
MSR series routers adopt modular design and support a wide range of optional SICs and DSICs. A SIC
occupies one SIC slot of an MSR router and a DSIC occupies two SIC slots of a router. The SIC/DSIC
series interface modules provide abundant interfaces, such as synchronous/asynchronous serial
interface, Ethernet interface, E1/T1, ISDN BRI/PRI, ADSL, audio interface, Layer 2 switching interface,
and so on.
Among this series interface modules, the Layer 2 switching interface modules (SIC-4FSW and
DSIC-9FSW) each have a corresponding PoE-capable one, which can provide -48 VDC power to
remote powered devices (PDs, such as IP phone, WLAN AP, network camera) through straight-through
cables as long as installed in a PoE router.
For H3C MSR 20-40 and MSR 30 and 50 series routers that have four SIC slots, a
4FSW/1FEF/1FEA/1GEC/1ADSL/1ADSL-I interface module can only be installed in slot 2 or slot 4.

Introduction
SIC-4FSW/SIC-4FSW-PoE and DSIC-9FSW/DSIC-9FSW-PoE interface modules are 4/9-port 10/100
Mbps Ethernet Layer 2 SIC interface modules 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 network directly.
SIC-4FSW-PoE/DSIC-9FSW-PoE interface modules can supply power to powered devices (PDs)
through power over Ethernet (PoE).
Functions supported by interface modules are as follows.
z
Effective transmission distance of 100 meters with category-5 twisted pair cables (both crossover
and straight-through);
z
Effective transmission distance of 100 meters between any interfaces with category-5 twisted pair
cables (both crossover and straight-through);
z
Operating speeds of both 100 Mbps and 10 Mbps and autosensing;
