INTRODUCING 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.

4 CHAPTER 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.

INTRODUCING 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.

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:

1 Power off the router.

2 If 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.

3 Check 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.

4 Check 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.

18 CHAPTER 2: INTRODUCING ROUTER 5012 SICS

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.
