Chapter 2 Smart Interface Cards
MSR series routers adopt modular design and support a wide range of optional smart
interface cards (SICs) and double smart interface cards (DSICs). A SIC interface card
occupies one SIC slot of an MSR router and a DSIC interface card occupies two SIC
slots of a router. The SIC/DSIC series interface cards 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 cards, the Layer 2 switching interface cards (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.
Note:
For H3C MSR 20-40 and MSR 30 and 50 series routers which have four SIC slots, a
4FSW/1FEF/1FEA/1GEC/1ADSL/1ADSL-I interface card can only be installed in slot 2
or slot 4.
2.1 SIC-1FEA
2.1.1 Introduction
1-port 10Base-T/100Base-TX Ethernet interface card (SIC-1FEA), in which FE stands
for Fast Ethernet and A is used to differentiate SIC-1FEA from the 1FE module.
SIC-1FEA is used to implement the communication between Routers and LANs. It
supports:
z
Effective transmission distance of 100 meters with category-5 twisted pair cables;
z
Operating speeds of both 100 Mbps and 10 Mbps and autosensing;
z
Both full duplex (in common use) and half-duplex operating modes.
Note:
For H3C MSR 20-40 and MSR 30/50 series routers, a SIC-1FEA interface card can
only be installed in SLOT2 or SLOT4.
