Installing/Removing a
SIC
WARNING: H3C MSR 20/30 Series Routers do not support online insertion and
removal of SICs and MIMs. Before implementing any of the following operations,
wear an anti-static wrist strap and ESD-preventive glove, and make sure that the
power of the Router has been turned off and the power cord has been
unplugged. Otherwise, you may get an electric shock or your router may get
damaged.
CAUTION: When replacing/installing an interface card or module, note the
following
■ Do not damage the EMI gaskets on the card/module panel. They can filter
electromagnetic interference of the router.
■ To protect the card or module against ESD damage, hold the card/module by
its edge and do not touch the components on the circuit board. Put the
uninstalled interface card or module on an antistatic tray.
■ If you do not install a new card or module after removing the old one, replace
the blank filter panel to keep off the dust and ensure adequate ventilation of
the router.
Tools required
■ Flat-module screwdriver
■ ESD-preventive wrist strap and ESD-preventive glove
Removing the blank filler panel in a SIC slot

CAUTION: The EMI gaskets on the FIC panel can filter electromagnetic
interference of the router. Do not damage them when uninstalling or replacing an
FIC.
If you do not install a new FIC after removing the old one, replace the blank filter
panel to keep off the dust and ensure adequate ventilation of the router.
Troubleshooting19
The MSR 50 series supports hot swapping. Thus, you can remove or install FICs
when the router is running without disconnecting the power supply. But before
that, you must first execute the remove slot command; otherwise, unknown
errors might occur. When you replace the removed FICs, you do not need to
execute the undo remove slot command however.
If you execute the remove slot command inadvertently, you can cancel that
operation by using the undo remove slot command.
Tools required
■ ESD-preventive wrist strap
Removing a FIC
Step 1: Place the router with the front panel forward.
Step 2: Remove the cables connected to the FIC.
Step 3: Loosen the captive screws at both sides of the FIC.
Step 4: Push the ejector levers at both sides of the FIC outward, pull the FIC out of
the slot along the guides until disengaging it totally from the slot.
Installing a FIC
Step 1: Place the router with the front panel forward.
Step 2: Align the remote edge of the FIC with the slot edge, push it into the slot,
push the ejector levers inward until it presses against the FIC panel (the angles
thus formed between the FIC panel and the levers are the minimum angles).
Step 3: Fix the FIC in the chassis by fastening the captive screws.
Repeat these steps to install all the other FICs.
TroubleshootingH3C Series Routers provide LEDs, thus facilitating you to make sure whether a
SIC/MIM/FIC is properly installed by viewing their state as follows:
After the installation of a SIC/MIM/FIC, turn on the power and view the
corresponding LEDs on the cover of the Router chassis: ON means that the
SIC/MIM/FIC is operating normally and OFF means that the Power-On Self-Test
(POST) of the SIC/MIM/FIC has failed.
If the installed SIC/MIM/FIC is in abnormal state, check that:
■ Proper interface cable is used;
■ The LEDs on the panel of SIC/MIM/FIC are displaying normally (see the section
introducing the SIC/MIM/FIC for its LED status and description);
■ The SIC/MIM/FIC accepts the configuration and works well using the display
command.

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.

module. SIC-1FEA is used to implement the communication between Routers and
LANs. It supports:
■ Effective transmission distance of 100 meters with category-5 twisted pair
cables;
■ Operating speeds of both 100 Mbps and 10 Mbps and autosensing;
■ Both full duplex (in common use) and half-duplex operating modes.
For H3C MSR 20-40 and MSR 30/50 series routers, a SIC-1FEA interface card can
only be installed in SLOT2 or SLOT4.

Interface CableNormally, category-5 twisted pair cable is adopted to connect the 10BASE-T
/100BASE-TX Ethernet interface to the Ethernet, as shown in the following figure:
Figure 6 Ethernet cable
Ethernet cables fall into two categories: straight-through cables and crossover
cables, specifically,
SIC-1SAE23
■ Straight-through cable: the wire sequences of the twisted pair cable crimped in
the RJ-45 connectors at both ends are completely the same. It is used to
connect terminal devices (such as PCs, routers) to Hubs or LAN Switches.
■ Crossover cable: The wire sequences of twisted pair cable crimped in the RJ-45
connectors at both ends are different. It can be used to connect two terminal
devices (such as PCs and Routers). You can such kind of cables by yourself if
necessary.
For the pinouts, identification and making methods of these two kinds of network
cables, see Low-End and Mid-Range Series Routers Cable Manual.
Connecting the Interface
Cable
If the SIC has been properly installed, follow these steps to connect the interface
cable:
Step 1: Connect the Ethernet port of SIC to a PC or router using a crossover cable
and to a Hub or LAN Switch using a straight-through cable;
Step 2: Check the status of LINK LED on the SIC-1FEA panel: ON means the link is
connected and OFF means the link is not connected. In the latter case, check the
line.
SIC-1SAE
IntroductionSIC-1SAE, 1-port enhanced high-speed synchronous/asynchronous serial interface
card, provides functions similar to SA, but its serial interfaces support more
protocols, such as RS449, X.21, and RS530.

Interface CableThe SIC-1SAE uses a synchronous/asynchronous serial interface cable with DB-28
connectors for connection.
Before connecting to a port on the SIC-1SAE, confirm the line properties of the
interface to select an appropriate cable from the following cable options:
■ V.24 (RS232) DTE cable: DB-25 (male) connector at the network end
SIC-1SAE25
■ V.24 (RS232) DCE cable: DB-25 (female) connector at the network end
■ V.35 DTE cable: 34PIN (male) connector at the network end
■ V.35 DCE cable: 34PIN (female) connector at the network end
■ X.21 DTE cable: DB-15 (male) connector at the network end
■ X.21 DCE cable: DB-15 (female) connector at the network end
■ RS449 DTE cable: DB-37 (male) connector at the network end

These cables are optional items. Please select one when purchasing a SIC-1SAE
card; by default, the cable is not provided.
WARNING:
■ Before plugging or unplugging the interface cable connected to the SIC-1SAE
card, power off the router. Online insertion or removal tends to damage the
port and even the device.
■ Before connecting the SIC-1SAE card to a remote device, identify the type of
the device, such as its synchronous/asynchronous mode and DTE/DCE mode,
and the signaling criterion, baud rate and time clock required by the access
device.
Step 1: Choose a synchronous/asynchronous serial interface cable depending on
the type of the interface on the remote device.
Step 2: Plug the DB-28 connector of the cable to the DB-28 port on the SIC-1SAE.
Step 3: Connect the other end of the SAE cable to:
■ Port of CSU/DSU if the WAN is a DDN line.
■ Serial port on an analog modem if the WAN is a dial-up line.
Step 4: Check the behavior of the LINK LED on the card panel. It is OFF when the
line is faulty and signal is out of synchronization. Check the line for the cause.
■ Transmission/Receiving and handling of E1 data streams;
■ CE1 (channelized E1) access;
■ ISDN PRI function;
■ Remote loopback and local loopback functions, facilitating fault test and
location.
It is possible to use the card for multiple purposes through different
configurations.
Following are the differences between SIC-1EPRI and 1-port Fractional E1 interface
card (SIC-1E1-F):
■ FE1 mode of SIC-1E1-F can support only one channel bundle (the rate is n ×
64kbps, n=1-31), while the 31 channels can be grouped into multiple arbitrary
bundles by SIC-1EPRI;
■ SIC-1E1-F does not support PRI mode.
