INTRODUCING THE ROUTER 3000

1

FAMILY

Routers in the 3Com® Router 3000 Family provides the following types of ports:

■ Ethernet port

■ Synchronous/asynchronous serial port

■ Auxiliary (AUX) port

■ ISDN BRI S/T and U port

■ CT1/PRI port

■ E1/CE1/PRI port

These features allow you to combine the various networking technologies, such as
PSTN/ISDN, FR (Frame Relay), X.25, leased line, and T1 line. These multiple ports
also allow Router 3000 series routers to interoperate with the products of other
manufacturers.

Router 3000 routers use three types of memory:

■ Synchronous Dynamic Random Access Memory (SDRAM) — Saves router

operation system software

■ Flash memory — Saves router program files, configuration files and so on

■ Boot ROM — Saves the boot and initialization programs of the router

6 After the loading, press Enter to reboot the router.

Uploading files involves transferring them from a PC running the FTP client to a
router running the FTP server, through the router’s Ethernet port. This is called a
put operation.

Downloading files involves transferring them from the FTP server on the router,
through its Ethernet port, to the PC running the FTP client. This is called a get
operation. All FTP clients, including local and remote users, who are connected to
a router can upload and download if they pass user authentication.

Creating a Local FTP Upload/Download Configuration

To transfer files using FTP, you must create the appropriate configuration, as shown

Figure 23 and Figure 24, and described in the following procedures.

Maintaining Router Hardware

Opening the Cover of

Router Chassis

In preparation for the maintenance of your router hardware, have the following
tools:

■ Phillips screwdriver

■ ESD-preventive wrist strap and ESD-preventive glove

■ Static shielding bag

■ Chip extractor

CAUTION: Observe the following precautions when maintaining your router
hardware:

■ On the Router 3000, there is a seal on one of the screws on the chassis.

Contact your Service representative before you open the chassis.

■ Always maintain the router under the guidance of technical support personnel.

■ Confirm that all power supplies have been disconnected from the router when

performing hardware maintenance.

■ Wear an ESD-preventive wrist strap and ESD-preventive gloves during hardware

maintenance and ensure that the strap makes skin contact.

■ Use only the SDRAM provided by 3Com Corporation.

Use the following procedure to open the router chassis cover:

1 Turn off the power to router and remove the power cord.

2 Remove all port cables on the back panel of the router. Do not remove the PGND

cable.

3 Place the router upside down on a work surface. Remove the screws on the

bottom of the chassis with the Phillips screwdriver and set them aside.

4 Turn the router right side up, with the rear panel toward you.

5 Remove the captive screws on the rear panel with the Phillips screwdriver and set

them aside.

6 Raise the chassis cover until it is free of the bottom of the router, and put it to one

side.

Figure 25 Removing the Screws from the Bottom of the Router Chassis

Maintaining Router Hardware 47

Replacing the Boot ROM When a Boot ROM is damaged or when data becomes corrupted because of a

software failure and cannot be corrected, the Boot ROM should be replaced.

Router 3000 Boot ROMs are located at the same position on the mainboard, as
shown in

Figure 26 Boot ROM Location

Figure 26.

Boot ROM location

Closing the Router

Chassis Cover

CAUTION: Use a chip extractor to replace the Boot ROM.

To replace the Boot ROM:

1 Insert the top end of the chip extractor into the Boot ROM socket, turn inward

slightly, withdraw the extractor upward and lift the Boot ROM out.

2 Put the Boot ROM into the static shielding bag.

3 Insert the end of the chip extractor into the socket of the new Boot ROM.

4 Position the Boot ROM so that the beveled edge of the socket matches the

beveled edge on the Boot ROM and plug it into the Boot ROM socket.

CAUTION: Be careful not to damage or bend the pins at the bottom of the Boot
ROM. If the pins are bent, straighten them with needle-nose pliers.

To prevent cables from being pressed or cut off when you close the cover of the
router chassis, roll up all the cables and put them into the chassis before closing
the cover.

48 CHAPTER 4: MAINTAINING THE ROUTER

TROUBLESHOOTING

5

The Power LED is Off. If the power LED is off, verify that:

■ The power switch of the router is turned on.

■ The power supply switch is turned on.

■ The power cord of the router is connected properly.

■ The power supply suits the requirement of the router.

CAUTION: Do not plug in or unplug the power cord when the power is on. After
having checked the conditions in the previous list, if the power LED is still off,
contact your Service representative.

Nothing is Displayed on the Terminal after Power-On

After the system runs the power-on self-test (POST), if the system operates
normally, the start-up information is displayed on the console terminal. If the
configuration system has a fault, the terminal may display nothing.

If the terminal does not display any information after the POST, verify that:

■ The power system is operating normally.

■ The console cable is connected correctly.

If the power system is normal and the console cable is connected properly, there
may be something wrong with the console cable or the HyperTerminal
parameters. Check the cable or the parameters.

HyperTerminal parameters should have the following values:

■ Baud — 9600

■ Data bits — 8

■ Stop bit — 1

■ Parity — None

■ Flow control — None

■ Terminal emulation — VT100

If the parameter settings do not match these values, reconfigure them.

If the previous checks do not solve the problem, contact your Service
representative and follow the representative’s instructions.

50 CHAPTER 5: TROUBLESHOOTING

Illegible Characters Display on the Terminal after Power-On

If the system operates normally after the system runs the POST, the start-up
information is displayed on the console terminal. If the configuration system has a
fault, the terminal may display only illegible characters.

If the console terminal displays illegible characters after the POST, verify that the
HyperTerminal parameters are set properly, as follows:

■ Baud: 9600

■ Data bits: 8

■ Stop bit: 1

■ Parity: None

■ Flow control: None

■ Terminal emulation: VT100

If the parameter settings do not match these values, reconfigure them.

Ethernet Cable The Ethernet cable uses an RJ-45 connector and category 5 twisted pair cable.

The Router 3000 series routers provide a fixed 10/100BASE-TX fast Ethernet port
that uses category-5 twisted pair cable, as shown in

Figure 29 Ethernet Cable Assembly

The Ethernet cables are classified as straight-through network cable and crossover
network cable. They have the following features:

■ Straight-through network cable — The sequences of the wires crimped at the

RJ-45 connectors of the two ends are the same. The cable is used in the
connection between a terminal device, such as a PC or a router, and the Hub or

Figure 29

Serial Port Cable 53

LAN Switch. Straight-through network cables are delivered along with the
router.

■ Crossover network cable — The sequences of the wires crimped at the RJ-45

connectors of the two ends are different. The cable is used in the connection
between the terminal device, such as a PC or a router, and another terminal
device. You can create this cable yourself, if necessary.

You can use Ta bl e 28 as a reference while distinguishing or preparing the two
kinds of Ethernet cables. While preparing the Ethernet cables, follow the
chromatogram given in this table to arrange the wires. Otherwise, communication
quality will be affected even though the equipment at two ends is connected.

Serial Port Cable The synchronous/asynchronous serial port cable is connected to a DB-50

receptacle. You must select the appropriate cable for the protocol.

54 CHAPTER A: OPTIONAL CABLE SPECIFICATIONS

Synchronous and

Asynchronous mode

V.35 and V.24 (EIA/TIA-232) standards support synchronous operating mode,
while only V.24 (EIA/TIA-232) standard supports the asynchronous operating
mode. The maximum transmission distance and baud rate of the signal vary with
the operating mode. See

Cable Pinouts

DTE and DCE mode

The synchronous serial port can operate in both DTE mode and DCE mode. For
two devices connected directly, one device should operate in DTE mode, and the
other device should operate in DCE mode. The DCE mode device provides a
synchronous clock and specifies the transmission rate, the DTE mode device
accepts the synchronous clock and communicates at the specified transmission
rate. Usually, the router serves as the DTE device. To determine whether the device
is a DTE or a DCE, refer to the user manual for the device.

Ta bl e 30 helps identify

DTE and DCE devices.

Equipment

DTE male PC or router

DCE female Modem, multiplexer or CSU/DSU

Type of Interface Typical Equipment

In general, the asynchronous serial interface is connected to a modem or a
terminal adapter (TA) to act as the dial-up interface. In this case, it is unnecessary
to determine whether the device is DTE or DCE, you must only select the
appropriate baud rate.
