1INTRODUCING THE ROUTER 5000
FAMILY
Routers in the 3Com Router 5000 Family support two types of interface modules:
■Smart Interface Cards (SICs) — small WAN cards
■Multifunctional Interface Modules (MIMs) — larger WAN cards
The routers can be flexibly configured by changing or extending SICs or MIMs, to
provide different functions. Your router provides slots for the following modules:
■Router 5012 — 2 SICs and 1 MIM
■Router 5232— 3 MIMs
■Router 5642 — 4 MIMs
■Router 5682 — 8 MIMs
See Chapter 2 for the list of SICs that are supported for the Router 5012.
See Chapter 3 for the MIMs that are supported for all Router 5000 Family routers.
Software features of the Router 5000 Family include:
■WAN routing capability — Router 5000 Family routers provide full routing of IP
using RIP, OSPF, IPX or BGP-4. They also provide WAN support for ISDN, Frame
Relay, X.25, PPP, PPPoE, MP, E1, T1, HDLC/SDLC, Sync / Async, Ethernet
(broadband)
■Security — Router 5000 Family routers offer RADIUS authentication, advanced
filtering, firewall, and support for VPN protocols, including IPSec with IKE, GRE
and L2TP
■Powerful backup functionality — Router 5000 Family routers support interface
backup, link backup and route backup. The backup can be between a leased
line and a dialup line, between a leased line and a virtual link, or between
dialup lines. The Router 5000 Family supports mutual backup between such
networks as leased line, X.25, PSTN, ISDN, and Frame Relay.
■Voice / Data Convergence — Router 5000 Family routers support QoS,
Multicast, 802.1q VLAN, multi-links, load balancing and compression
■Resilience — Router 5000 Family routers support Virtual Router Redundancy
(VRRP), Backup Center (Configuration / Port), dial on demand routing, and
multilink
■E1/CE1/PRI and CT1/PRI compatibility — Router 5000 Family routers provide
CE1 (channelized E1) access, and the CE1 interface is compatible with the E1
interface. In addition, the ISDN PRI function can be implemented on the CE1
interface. CT1 (channelized T1) access is also provided and the CT1 interface is
compatible with the PRI interface. This compatibility allows one card to be used
for multiple purposes.

4CHAPTER 1: INTRODUCING THE ROUTER 5000 FAMILY
■5012High density ports — The Router 5682 supports a 28 2Mbps sync serial
port, which can connect to leased line, Frame Relay, and X.25 networks.
■Fast Ethernet access — Router 5000 Family routers support 100 Mbps access to
the local Ethernet and flexible networking configuration.
Router 5000 Family
Software The Router 5000 Family software operates in Synchronous Dynamic Random
Access Memory (SDRAM). Flash memory stores router program files and
configuration files. Boot ROM stores boot and initialization programs.
Data Security The Router 5000 Family routers provides data security through the following
features:
■Authentication protocols, such as Password Authentication Protocol (PAP),
Challenge Handshake Authentication Protocol (CHAP), and Remote
Authentication Dial In User Service (RADIUS)
■Firewall and packet filtering to prevent intrusions from external networks
■Virtual Private Network (VPN) for example, GRE, L2TP; IP Security (IPSec); and
Internet Key Exchange (IKE) technologies, to guarantee the security of the
network in the Internet environment
■Backup solutions based on backup center technology
Online Upgrades Application and configuration software can be upgraded online with 512 KB Boot
ROM and 32MB Flash memory.

2INTRODUCING ROUTER 5012 SICS
The Router 5012 has 2 smart interface card (SIC) slots. You can install any two of
the following SICs in your Router 5012 router:
■Ethernet interface card
■1-port 10/100 BASE-T SIC
■WAN interface card
■1-Port Serial SIC
■2-Port ISDN S/T SIC
■2-Port ISDN U SIC
■1-Port Fractional E1 SIC
■1-Port Fractional T1 SIC
■1-Port Analog Modem SIC
1-port 10/100 BASE-T
SIC The 1-port 10/100 BASE-T SIC enables communication between routers and LANs
and supports the following functions:
■An effective transmission distance of 100 meters over category-5 twisted pair
cables.
■Operation at the speed of 10Mbps or 100Mbps autosensing.
■Support for both full duplex and half-duplex operating modes.
You can install only one 1-port 10/100 BASE-T SIC in the Router 5012 and it can
only be installed in SLOT 2.
Figure 9 shows the 1-port 10/100 BASE-T SIC

Table 12 lists the status descriptions of the 1-port 10/100 BASE-T SIC LEDs.
Cables 3Com recommends that you use category-5 twisted pair cable to connect the
10BASE-T /100BASE-TX Ethernet interface to the Ethernet, as shown in Figure 11.
Figure 11 Ethernet Cable
Ethernet cables are grouped into two types; standard network cables and
crossover cables:
■Standard network cable, or straight-through cable — The wire sequences of
the twisted pair cable are terminated by RJ-45 connectors at both ends, which
are identical. This cable connects the terminals, such as PCs and routers, to

hubs or LAN switches. A standard network cable is shipped with the Router
5012.
■Crossover cable — The wire sequences of the twisted pair cable are terminated
by RJ-45 connectors that are different at either end. This type of cable can
connect terminal equipment, such as PCs and routers, to other terminal
equipment. You can create this kind of cable yourself, if necessary.
The 1-port 10/100 BASE-T SIC ships with the interface cables. While preparing
network cables, use the shielded cable first to ensure electromagnetic
compatibility.
To connect the Ethernet cable:
1Power off the router.
2If the Ethernet cable is a standard, straight-through cable, plug one end of the
cable into the Ethernet port of the 1-port 10/100 BASE-T SIC and the other end
into the hub or LAN switch.
3Check the SLOT2 LED on the front panel of the router after you power on the
router. If the LED is on, the interface card has passed the power-on self-test
(POST). If the LED is off, the POST failed and you should contact your Service
representative.
4Check the status of LINK LED on the 1-port 10/100 BASE-T SIC panel. If the LED is
on, the link is connected. If it is off, the link is not connected. Check the cables
and the connections.
1-Port Serial SIC The main functions of the 1-Port Serial SIC are:
■Transmisson and processing of synchronous or asynchronous serial data
streams
■Operation in different modes, such as DTE/DCE, depending on the applications
■Automatic detection of the type of external cable without manual
configuration
■Local loop and remote loopback to facilitate fault testing and locating.
In different operating modes, a serial port supports different signal standards and
baud rates. The maximum transmission distance of the signals is related to the
baud rate setting. Table 13 lists the relations between cable type, baud rate setting
and signal transmission distance.

16 CHAPTER 2: INTRODUCING ROUTER 5012 SICS
The baud rate cannot exceed 64 kbps if the V.24 cable is used and the interface
operates in synchronous mode.
Introduction to DTE and
DCE The synchronous serial port supports both data terminal equipment (DTE) and data circuit-terminating equipment (DCE) operating modes. If two devices are
directly connected and one operates in the DTE mode, the other will operate in
the DCE mode. The DCE device provides the synchronous clock and specifies the
communication rate. The DTE device receives the synchronous clock and
communicates at the specified rate. Generally, the router is used as a DTE device.
To make sure that the device is a DTE or DCE, refer to the manual shipped with
this device. Table 14 provides additional information to help you identify the type
of the device.
An asynchronous serial port is generally used as dialing port and is connected to a
modem or a terminal adapter (TA). In this case, regardless of the operating mode
of the device, you need to select only the appropriate baud rate for the port.

Table 16 lists status descriptions of the 1-Port Serial SIC LEDs.
Cables The 1-Port Serial SIC cable is a serial port cable. There are four possible cables that
you can use with the 1-Port Serial SIC. You must order the cable you need from
3Com when you order the interface card. To prevent damage to your router and
to avoid voiding your warranty, use only the appropriate cable supplied by 3Com.
The end of these cables that connects to the router has a DB-50 connector. The
type of network connector depends on the line type or the type of device at the
network end. These cables are described in Table 17 and are illustrated in
Figure 14, Figure 15, Figure 16, and Figure 17.
