After connection, power on the router. The startup information of the router is
displayed on the console terminal.

Before you install a SIC or MIM, assemble the following equipment:

■ Flat-blade screwdriver

■ Anti-static wrist strap

The Router 5000 Family routers do not support hot swappable SICs and MIMs. To
avoid injury from electric shock or damage to a router, put on an anti-static wrist
strap, make sure that power to the router has been turned off and that the power
cord has been unplugged before performing any of the following operations.

Before you can install a SIC or MIM, you must remove the filler panel from the slot.
Remove the captive screws of the blank filler panel by unscrewing them in a
counter-clockwise direction with the flat-blade screwdriver, as shown below.

Do not remove the blank filler panel with black film above SLOT0.

To install a SIC or MIM:

1 Turn the router so the rear panel faces you.

2 Turn off the power switch of the router and unplug the power cord.

3 Match the remote edge of the module with the slot on the router's rear panel.

4 Push the module into the router until its front panel is level with the back panel of

the router.

5 Fasten the module into the router with the captive screws.

6 Power on the router, and check the LED of the corresponding slot on the front

panel. After the initialization of the module, if the LED for the corresponding slot is
on, the module is operating normally. If the LED for the corresponding slot remains
off, the POST for the module has failed and you should contact your Service
representative.

Command Line Interface The command line interface of the Router 5000 routers provides commands to

configure and manage the router. The command line interface has the following
characteristics:

■ Performs local configuration through the console port.

■ Performs local or remote configuration through the telnet command, which

can be used to log on directly and manage other routers.

■ Implements the configuration on the router through the terminals (the

asynchronous interface, including those connected to the AUX port and AS
port) in dumb terminal mode.

■ Configures the hierarchical user protection (guest, operator, administrator).

Only administrator users are authorized to configure and manage the routers.

■ Online help, available by typing ? at any time.

■ Provides network diagnostic tools, such as Tracert and Ping, to quickly diagnose

the availability of the network.

■ Provides detailed debugging information to diagnose network faults.

■ The command line interpreter adopts fuzzy search for the keywords of the

command. A conflict-free keyword if entered, will be interpreted accordingly.
For example, for a display command, you can enter dis.

32 CHAPTER 3: BOOTING AND CONFIGURING THE ROUTER

To facilitate the management of the router in the system view, all the commands
are grouped. Each group corresponds to a view. Users can use these commands to
switch between different views. Many commands are limited to use in a single
view. Other commands (such as ping, display current-configuration, interface)
can be executed in all views.

The appearance of the prompt "ftp>" means that you can begin the
upload/download operation.

3 Upload/Download the application files, Boot ROM program or configuration files.

By default, the application file and configuration file on the router are respectively
named "system" and "config", the file of the extended Boot ROM program
segment is named "bootrom", and the entire Boot ROM file name defaults to
bootromall.

Introduction 41

Upload the application program file or Boot ROM program or configuration file.

ftp>put
local file (Input the name of appplication/Boot ROM
program/Configuration file to be uploaded.)
remote file (Input the name of appplication/Boot ROM
program/Configuration file to be saved at the router side after
uploading.)

After the uploading is completed, the prompt "ftp>" will be displayed again.
Enter <dir> to display the name and size of the file on the router. The size of the
configuration file will be the same as that of the original file on the host if the
uploading is successful.

CAUTION: After you have uploaded Boot ROM program using the put command,
you should immediately use the upgrade bootrom [ full ] command to decompress

Installing a Module The procedure for installing a SIC or MIM is provided in the following list and

shown in

Figure 28.

1 Turn the router so the rear panel faces you.

2 Turn off the power switch of the router and unplug the power cord.

3 Remove the module and match its remote edge with the edge of the slot on the

rear panel of the router.

4 Push the module into the router until it closely matches the rear panel of the

router.

5 Fasten the module into the router with the captive screws.

6 Power on the router, and check the LEDs of the corresponding slot on the front

panel. After the initialization of the module, if the LEDs for the corresponding slot
are on, the module operates normally. If the LEDs for the corresponding slot
remain off, the POST failed and you should contact your Service representative.

Closing the Router

Chassis Cover

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.

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.

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.

44 CHAPTER 5: TROUBLESHOOTING

Illegible Characters
Display on the
Terminal after

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.

Power-On

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.

Repeated Reboot There are two possible situations in which the system reboots repeatedly:

■ After Now testing memory... displays

■ After System now is starting... displays, the system restarts repeatedly and

displays,

Copied program error.

Troubleshooting SICs
and MIMs

Repeated reboots are caused by damage to the SDRAM. You can check whether
the SDRAM has a fault by checking the LED status of the router. During the POST,
the SLOT0 – SLOT2 LEDs and SERIAL0 LED light first. If the SLOT0 and SLOT1 LEDs
are on instead, the SDRAM test has failed.

If the SDRAM is damaged, you must replace it. See “Replacing the SDRAM” on
page 82.

The LEDs on the Router 5000 Family routers indicate whether the modules are
properly installed. After the installation of a module, turn on the power and check
the corresponding LED on front panel of the router. If the LEDs are on, the POST
was successful and the router is working normally. If the LEDs are off, the POST
has failed. You can test it using the following steps:

■ Check that the port cable matches the port.

■ Verify that the module is in normal operation by observing its LEDs .

■ Use the display command to check whether the module or interface module

has accepted the configuration.

All LEDs of the Encryption Accelerator MIM Remain off after Startup

After startup, all LEDs should blink once. If all indictors are off, the module or
hardware on the module has not powered on. Check whether the power of the
integrated equipment is properly connected.

If the power of the integrated equipment is in normal operation, the fuse of the
module may have burnt out or the Complex Programmable Logic Device (CPLD)

Troubleshooting SICs and MIMs 45

may be out of order. In such a case and you should contact your Service
representative.

After Startup, All LEDs Remain On.

After startup, all LEDs should once, which indicates that the processor of the
module is in operation. If all LEDs are on, the module’s system bus is not operating
normally or the CPLD is out of order.

The RUN LED Remains On.

When the module is in operation, the RUN LED should blink, rather than remain
on. If the RUN LED remains on, the module is powered on, but not operating
normally. It is possible that the module has been forced to reset. If there are other
LEDs that remain on simultaneously (for example, the ACT, SPEED, or DENY LEDs),
the encryption card may be faulty. If the encryption card is operating normally, the
faults may have occurred in the host.

The RUN LED Blinks Rapidly During Sartup

The rapid blinking of the RUN LED indicates that the module is initializing. During
this period, if the DENY LED blinks occasionally, there is a memory fault. In this
case, contact your Service representative to check the module. If, during
initialization, the SPEED LED is occasionally on, the booting of the module system
has failed. In this case, check the system configuration or contact your Service
representative.

The RUN LED Blinks Slowly After Startup

The slow blinking of the RUN LED indicates that the module is in offline. Check
whether the router host is properly configured and supports the encryption card.

The ACT LED Remains On.

When the ACT LED is flashing green, the module is upgrading the firmware. If the
ACT indictor remains on, the software upgrade has failed and the software should
be upgraded once again. If the ACT LED remains on after a second attempt to
upgrade, contact your Service representative.

The DENY LED Blinks during Normal Operation

When the DENY indictor blinks during normal operation, the module performance
or capacity is not adequate for encryption demands. This situation is not a
software or hardware failure. It is results from the technical specification limit of
the existing encryption module version. If necessary, contact your Service
representative to upgrade the encryption module with greater processing
capability.

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

Figure 30 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 at each end are the same (see
connection between a terminal device, such as a PC or a router, and the Hub or
LAN Switch. Straight-through network cables are delivered with the router.

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

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

chromatogram given in this table to arrange the wires. Otherwise, communication
quality will be affected even though the equipment at two ends is connected.

50 APPENDIX A: CABLE SPECIFICATIONS

Serial Interface Cable Synchronous and Asynchronous Mode

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

The baud rate should not exceed 64 Kbps when the V.24 cable operates in
synchronous mode.

DTE and DCE Mode

The synchronous serial interface can operate in both DTE and DCE modes. For two
devices connected directly, one device should operate in DTE mode, and the other
device should operate in DCE mode. The DCE device provides a synchronous clock
and specifies the transmission rate, the DTE 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 21 Typical DTE and DCE

Type of Equipment Type of Interface Typical Equipment

DTE male PC or router

DCE female Modem, multiplexer or

CSU/DSU

The asynchronous serial interface generally is connected to a modem or a terminal
adapter (TA) to act as the dial-up interface. You do not need to determine if the
device is DTE or DCE, you must only select the appropriate baud rate.

The synchronous/asynchronous serial port cable is connected to a DB-50
receptacle. Proper connection cable needs to be selected for the protocol applied.

Four types of synchronous/asynchronous serial port cables are available. However,
these cables are optional and you must select the proper one based on your
requirements when you purchase the router All these types of cables have a DB-50
adapter at one end.

Serial Interface Cable 51

e

At the network end, the connector is different for each type of cable, as described
in the following list:

■ V.24 (EIA/TIA-232) DTE cable — DB-25 (male) adapter

■ V.24 (EIA/TIA-232) DCE cable — DB-25 (female) adapter

■ V.35 DTE cable — 34-pin (male) adapter
