2 Installation Preparations

Requirements on Environment

MSR 20 Series must be used indoors. To ensure the normal operation and prolong their service life, the following requirements for inst allation site must be met.

Requirements on Temperature/Humidity

To ensure the normal operation and prolong their service life, certain requirement s on temperat ure and humidity in the equipment room shall be met. If the relative humidity is too high, the insulation m aterials in it will deteriorate easily or even lead to electric leakage. Sometimes this will result in change to the mechanical performance of the materials and rusting of the metal compon ents. If the relative humidity is too low, the fastening screw will become loosen due to shrinkage of the isolation spacer. In an environment with dry climate, static electricity may be produced, putting the CMOS of the route r to risk. High temperature is of the greatest risk: for it will significantly degrade the router’s reliability, speed up aging process of the insulating materials, and shorten the service life of the router.

The requirements on the temperature and humidity for MSR 20 Series are shown in the following table:

Table 2-1 Temperature/humidity requirements in the equipment room

Temperature Relative Humidity

0°C to 40°C (32°F to 104°F)

Requirements on Cleanness

Dust is harmful to the safe operation of the Router. Dust on the chassis may result in static ab so rption, thus causing poor contact of the metal connection compon ents or points. Espe cially under the condition of low indoor humidity, dust is easier to be absorbed.

The requirements on the dust concentration and diameter are shown in the following table:

Table 2-2 Limitation on dust content in equipment room

Diameter (μm)

Concentration (particle/m³)

1.4 × 107

5% to 90% (noncondensing)

0.5 1 3 5

7 × 105

2.4 × 105

1.3 × 105

Besides the dust specifications, the equipment room of the Router should also meet the rigorous requirements for the content of salt, acid and sulfide. These harmful gases could accelerate the metal erosion and aging process of some part s. The specific limit s of these harmful g ases as SO

and CI2 are given in the following table.

, H2S, NO2,

Table 2-3 Harmful limits in equipment room

Gas Max (mg/m3)

SO2 0.2 H2S 0.006 NH3 0.05 CI2 0.01

Requirements on Electrostatic Discharge Prevention

Although many antistatic considerations have been given to MSR 20 Series, damage to the router’s circuit or even the whole equipment may still happen when the static electricity exceeds the tolerance threshold.

In the communication network to which the routers are connected, static induction mainly comes from two aspects: external electric fields such as outdoor high voltage power line or thunder and internal environment like flooring materials or the whole equipment structure. Thus, the following should be considered to safeguard the equipment against ESD.

z Make sure that the equipment and the floor are well grounded. z The equipment room is dust-proof. z Maintain an appropriate humidity and temperature. z Wear an ESD-preventive wrist strap and uniform when contacting the circuit board. z Place the uninstalled circuit board on the antistatic workbench, with its face upward, or put it into

the static shielding bag.

z When observing or removing the uninstalled circuit board, please touch the edge of the circuit

board, and avoid contacting the devices on it.

Requirements on Electromagnetic Environments

The interference sources, no matter where they come from, af fect the routers with cap acitance couplin g, inductance coupling, radiation of electromagnetic wave, common impedance (including the grounding system) or conducting line (power line, signal line and transmission line etc.). So the following should be considered:

z Take effective measures to prevent the power system from being interfered with by the power grid

system.

z Use an earthing system or lightning protection grounding different from that for the power supply

equipment and keep them as far as possible.

z Keep the router far away from the radio launcher, radar launcher, and high-frequency devices

working in high current.

z Use electromagnetic shielding when necessary.

Requirements on Preventing Lightning

Although many measures have been taken to protect MSR 20 Series from lightning, if the lightning intensity exceeds a certain range, damage to the router may still happen. To protect the router from lightning better, the following should be considered:

z Ensure the PGND wire of the chassis is well grounded.

2-2

z Ensure the ground point of the socket of AC power supply is well grounded. z To enhance the lightning protection capability of the power supply, a lightning arrester could be

installed at the input end of the power supply.

z As for the signal line outdoors to which the interface modules of MSR 20 series routers are

connected, such as ISDN line, telephone line, E1/T1 line, etc, a special lightning arrester should be installed at the input end of the signal line to enhance the lightning protection capability.

Checking the Rack

When installing MSR 20 Series Routers, observe the following:

z There is spacing reserved at the air inlet and outlet in the router so as to facilitate the radiation of

the router cabinet.

z Make sure that the rack has a good ventilation system. z Make sure that the rack is sturdy enough to support the weight of the device and the installation

accessories.

z Make sure that the rack is well-grounded.

Safety Precautions

Routers play a key role in data communications network. Please pay attention to the following:

It indicates that this operation is incorrect and may seriously damage the router or

endanger the operator . Please follow the correct operation procedures for sake of safety.

It indicates that during the installation and usage of the router, the operation needs

attention. If this operation is performed incorrectly, it might affect the operation of the router. When installing or working on the router, you are recommended to:

z Keep the router far away from the heat sources and water/liquid. z Make sure that the router has been correctly grounded. z Wear an ESD-preventive wris t strap in installation and maintenance, making sure that the strap

has good skin contact.

z Do not hot swap the interface modules and interface cards of the router. z Do not hot swap any cable. z Correctly connect the interface cable for the router. Do not connect the telephone cable (including

the ISDN cable) to the AUX port or the console port.

z Use laser with caution. Do not directly stare into apertures or fiber-optic connectors that emit laser

radiation.

z Adopt uninterrupted power supply (UPS).

The normal connection of the protection ground (PGND) on the router chassis is an essential safegua rd against the lightning shocks and interference. You must correctly connect the PGND when installing o r using the router.

The power input end of MSR 20 Series router is connected to a noise filter. The neutral point of the noise filter is directly connected to the chassis and is called protection ground (PGND). The PGND wi re must be well grounded, so as to safely conduct the faradism and leaky electricity to the earth ground, and thereby improve the capability of the whole device to guard against the electromagnetic interference. This PGND wire can also protect the router against the lightning caused by the connection with the external network lines, such as E1/T1 line, ISDN/PSTN line.

The grounding screw of MSR 20 Series Router, which is marked with grounding label, is located near the AC power socket and its switch on the rear panel of the chassis, as shown in the following figure:

Figure 3-4 Grounding terminal of the router

Use a PGND wire to connect the screw to the earth ground, and the grounding resistance shou ld not be greater than 5-ohm. Likewise, if the router is installed in a 19-inch st andard rack, this ra ck is required to be grounded too.

When the router is in normal operation, it is required to be well gro unded. Otherwise, the rout er cann ot reliably avoid lightning, which may damage the router itself and even the peer device.

AC power socket (recommended)

You are recommended to use a three-terminal single-phase power socket with ground contact, which must be grounded reliably. Normally, the ground contact of the power supply system in a building was buried during construction and cabling. Still, before connecting the AC-input power cord, you must make sure that the power supply of the building is well grounded.

Connecting the AC-input power cord

Step 1: Make sure that the PGND is securely conn ected to the earth ground. Step 2: When the power switch of the router is in the OFF position, insert one end of the power cord

accompanying the router into the power socket on the chassis rear pan el, and connect the other end of the cable to an AC po wer source at your installation site.

Step 3: Place the power switch of the router to the ON position. Step 4: Check that the PWR LED on the front panel of the router is on for correct connection.

Connecting the Console Terminal

Console port

MSR 20 series provides an RS232 asynchronous serial console (CON) port for router configuration, through which you can complete the configuration of the router. For its attributes, refer to

Configuration Fundamentals

In general, the configuration steps are as follows:

4-5

Step 1: Before configuring the router, the networking requirements should be made specific, which include networking purpose, the role of the router in the network, the division of subnets, WAN type and transmission medium, the network security policy and reliability.

Step 2: Based on the above requirements, draw a clear and integrated networking diagram. Step 3: Configure the WAN interface of the router. First, configure the physical operating parameters

(e.g., the operating mode of the serial interface, baud rate and synchronous clock) of the interface according to the transmission medium of the WAN. For the dial-up interface, the user also needs to configure DCC parameters. Then, configure the link layer protocol encapsulated on the interface and the related operating parameters according to the WAN type.

Step 4: Configure the IP addresses or IPX network n umbers of all the interfaces on the router according to the division of the subnets.

Step 5: Configure the routes. If it is necessary to enable a dynamic routing protocol, the user should configure the related operating parameters of the protocol.

Step 6: If special security is required, perform the security config ur ation for the router. Step 6: If special reliability is required, perform the reliability configuration for the router. See MSR 20/30/50 Series Routers User Manual for the configuration details of the protocols or

functions of the router.

Basic Configuration Procedures Command Line Interface

Characteristics of the command line interface

The command line interface of MSR 20 Series Routers provide s a number of configuration commands, which can be used to configure and manage the router. The command line interface has the following characteristics:

z Performs the local configuration through Console port z Performs the local or remote configuration through telnet command, which can be used to directly

log on and manage other routers.

z Users can enter “?” anytime to get online help. z Provides network diagnostic tools, such as Tracert and Ping, to quickly diagnose the availability of

the network.

z Provides all kinds of detailed debugging information to diagnose network faults. z The command line interpreter adopts fuzzy search for the keywords of the command. If the user

enters the conflict-free keyword for a command, the command will be interpreted accordingly. For example, for a display command, the user can just enter dis.

Command line interface

The command line interface of MSR 20 Series routers provides plenty of configuration commands. All the commands are grouped in system view . Each group corre sponds to a view. The user can use these commands to switch between different configuration views. In general, only certain commands can be executed under a particular view. But some common commands (such as ping and display current-configuration) can be executed in all views.

4-6

Arranging Slots and Numbering Interfaces

Slot arrangement

The MSR 20 series provides many types of interfaces, such as console, AUX, Ethernet, serial (synchronous/asynchronous), and asynchronous port. The following describes how these interfaces are numbered.

Interface numbering

The MSR 20 Series Router interface adopts “two dimension” numbering rules, sh own in the following:

4-7

z The interfaces are represented by interface-type X/Y, where interface-type can be serial,

asynchronous, or Ethernet, and so on; X specifies the slot number; Y specifies the interface number.

z Different interfaces on an interface module share the same slot number X. z For every interface, Y starts from 0 and Y indicates the interface sequence on the interface module,

from left to right.

If you install an SIC-1FEA and an SIC-4FSW respectively in SLOT1 and SLOT2 on the AR MSR 20-20, the Ethernet interfaces are numbered as follows:

z Fixed Ethernet interfaces are Ethernet 0/0 and Ethernet 0/1; z The Ethernet interface on the SIC-1FE is Ethernet 1/0; z The Ethernet interfaces on the SIC-4FSW module are Ethernet 2/0, Ethernet 2/1, Ethernet 2/2 and

Ethernet 2/3.

Introduction

Files

BootROM program file

The file is used for booting application at boot. A complete BootROM file includes two segments: basic and extended.

Application program file

The router is available with Dual Image function. By default, the system defines and attempts to boot in order with three boot files: main, backup, and secure, provided they are available with CF card. If the router fails to boot with the secure boot file, it prompts the boot failure. For more information about the boot files, refer to section “

Maintaining Application Program and Configuration File”.

The following table gives default names and types of boot files.

Table 5-1 Default names and types of the boot files

Boot file File name File type

Main boot file main.bin M Backup boot file backup.bin B Secure boot file secure.bin S

z The application programs for system boot can be type M, B and S, but not type N. You can store

them in Flash memory, but only one for each. For example, if an M+B file exists, it is impossible to have another M or B file. If you change the file type of another file to B, the M+B file becomes a type M file.

z You can modify the file name of an application file in CF card using the command after it boots. You

cannot modify the file type of a type S application image file, but you can modify the file type of type M/B and N application program files in the BootROM menu or using commands after the application program boots.

z Secure boot file is the last resort for system boot. You can download it in the BootROM menu and

must name it secure.bin. However, you cannot modify this file or change the type of another file to S. If you change the name of the secure boot file with the rename command after the system bo ots, the file is removed from CF card. To use the secure boot file after that, you need to download it again.

5-1

Configuration file

The file stores configuration information of the router. By default, the system defines and attempts to boot in order with three configuration files: main, backup,

and default, provided they are available with CF card. If the router fails to boot with the secure boot file, it prompts the boot failure. For more information about the boot files, refer to section “ Application Program and Configuration File”.

The following table describes the three configuration files.

Table 5-2 Description on the three configuration files

Configuration file File type Description

Main configuration file M Used by the system for booting by default.

Maintaining

Backup configuration file B

Used by the system for booting when it fails to boot with the main configuration file.

Used by the system for booting when it fails to boot with the backup configuration file. If the system fails to boot with the default configuration file, it boots with

Default configuration file M/B/N

null configuration. The name of the default configuration file has something to do with the router brand. The main and backup configuration operations on the default configuration file is the same with common configuration files.

z The configuration files for system boot can be type M, B and default configuration file of type N, but

not non-default configuration file of type N (i.e. neither M nor B).

z You can modify the file name of a configuration file in CF card using the command after it boots.

You cannot modify the type of the default configuration file, but you can modify the file type of type M/B and N configuration files in the BootROM menu or using commands after the application program boots.

You can store them in Flash memory, but only one for each. For example, if an M+B file exists, it is impossible to have another M or B file. If you change the file type of another file to B, the M+B file becomes a type M file.

5-2

z The file name cannot be longer than 64 characters (including drive letter and a string terminator. If

the drive letter is “CF: /”, the file name can be at most [ 64-1-4 ] = 59 characters in length; or, errors will occur in file operation. Typically, the file name is recommended to be not more than 16 characters.

z The extension ASCII characters (ASCII>=128) and invisible characters (ASCII<33) cannot be

included in the file name.

z The following characters cannot be included in the file name: ”, ‘, ?, \, space, *, |, <, /, :, >, ~. z The character “.” can be included in the file name, but cannot be the first or last character of the file

name. Two consecutive “.”s are not allowed.

Software Maintenance Methods

z Upgrading BootROM and application program using XModem protocol through serial port. z Upgrading application program from TFTP/FTP server through Ethernet interface in BootROM. z Uploading/downloading application program and configuration file from TFTP/FTP server via

command lines.

z BootROM program is upgraded through binding with the Comware version. You do not need to

upgrade it separately. The system automatically upgrades BootROM to be the latest version while upgrading Comware.

z Check the current version of BootROM and application program before upgrading. For the

association between Comware version and BootROM program, see the corresponding Release Notes.

Modifying Serial Port Parameters

Sometimes, we need to change the serial baud rate to higher in order to save upgrade time, or to lower to guarantee transmission reliability. This section depicts how to adjust serial baud rate.

Enter <2> in the main BootROM menu to enter the serial submenu. Then, enter <5>, and the system prompts to change serial baud rate.

========================<BAUDRATE SET>======================= |Note: Change The HyperTerminal's Baudrate Accordingly, | | Press 'Enter' to exit with things untouched. | |--------------------<Baudrate Available>-------------------| | <1> 9600(Default) | | <2> 19200 | | <3> 38400 | | <4> 57600 | | <5> 115200 | | <6> Exit | ============================================================= Enter Your Choice(1-6):

Select a baud rate, <5> for 115200 bps for example. The following prompt appears:

Change the baudrate on PC side first!

Since the router serial baud rate is modified to 115200 bps, whereas the terminal baud rate remains to be 9600 bps, they can not communicate with each other. Change the baud rate of your terminal to the same as that for software download.

Perform the following operation:

5-9

Figure 5-2 Disconnect terminal

Click [File/Properties], and press <Configure…> to change baud rate to 115200 bps: Figure 5-3 Modify baud rate

Click [Call/Call] to establish new connection. Figure 5-4 Establish new connection

Then, press <Enter> to prompt current configuration baud rate and return to the previous menu. The system prompts:

The current baudrate is 115200

5-10

Restore the baud rate in the HyperTerminal to 9600 bps (the default) after upgrading the BootROM. This is to ensure that information can be displayed on the console screen after system boot or reboot.

Upgrading BootROM

First, enter <7> in the main BootROM menu (refer to section “Main BootROM Menu”) to enter the BootROM operation submenu, under which all BootROM operations are completed. Refer to section

Upgrading Application Program Through Ethernet Interface

TFTP (Trivial File Transfer Protocol) is a protocol of the TCP/IP suit that is used to transfer trivial files between clients and the server. It provides not-so-complex and low-cost file transfer services. Carried over UDP, TFTP provides unreliable data transfer services and does not provide access authorization and authentication mechanism. It employs timeout retransmission to guarantee the successful transferring of data. TFTP takes much smaller size than FTP.

FTP (File Transfer Protocol) is an application layer protocol in the TCP/IP suit. It mainly transfers files among remote hosts. Carried over TCP, it provides reliable and connection-oriented data transfer service but does not provide access authorization and authentication mechanism.

Step 1: Set up an upgrade environment. Figure 5-7 Set up TFTP/FTP upgrade environment

Connect Ethernet port 0/0 to a PC by using a crossover cable. Start TFTP/FTP program on the PC as the server, and set the path of TFTP/FTP server to point to the address of application program. You need to set user name and password if FTP server is used.

5-14

No TFTP/FTP Server is available with the MSR 20 series. You must install one yourself.

Step 2: Modify Ethernet pa rameters. Refer to section “

Configuring Ethernet Parameters” for details.

Step 3: Enter <3> to enter Ethernet submenu. For ex ample, when upgradi ng main application program, enter <2> to upgrade:

Loading... Done! 14323376 bytes downloaded. Input the File Name:

After the download is done, input the file name and begin to update:

Updating File main.bin........

Update Success!

Step 4: Enter <6> to exit to the main BootROM menu. Enter <1 > to boot from the CF card. Step 5: Set the updated application program to be the main boot file, i.e. the default boot file of the

system.

The system reboots. Enter <4> when it prompts the above information.

Enter the file control submenu and enter <2> to set the application file type.

5-15

Please set application file type in cf:

3. +Backup

4. -Backup

5. Exit Enter your choice(1-5):1

Enter "1" to set the selected application program to be the main boot file, i.e. the default boot file of the system.

Step 6: Enter <5> to exit to the main BootROM menu. Enter <1 > to boot from the CF card.

z The file in the CF card will be overwritten if the file name being input is the same with the original file

name in the CF card.

z Make sure the space on memory is sufficient. Or, the system prompts insufficient space:

Updating File main.bin Insufficient CF Card space or failed device writing operation

z The file updated will directly replace the original file of this type to become the only application

program. The main.bin file downloaded here will replace the original M file directly to become the main boot program.

z Refer to the section “Files” for detailed descriptions of file types. z Do not include path information in the filename input during upgrade. z You can set the main/backup attributes for the startup file under the root directory of the device

only.

Maintaining Application Program and Configuration Through Command Lines

After booting the router normally, you can upgrade and backup application program and backup and recover configurations under command line mode.

Maintaining the Router with TFTP Server

The TFTP service provided by the router is TFTP Client — the router serves as TFTP Client, and the file server serves as TFTP Server . You can input commands to upload the configuration file and application

5-16

program of the router to the file server, or download configuration file or application program to the router from the file server.

Configuring environment

Step 1: Set up hardware environment (refer to section “Upgrading Application Program Through Ethernet Interface” for details), and point the server path to the folder where the file is put.

Figure 5-8 Networking diagram for maintenance under command line mode

Configure the IP addresses of the two sides to be in the same network. In this section, the TFTP server is set to 192.168.0.1, and the Ethernet interface connected to it (Ethernet interface 0/0 in this example; so, any interface is OK) is set to 192.168.0.2. Both can use the ping command to check if the connection is successful.

Backing up and recovering application program and configure file

After finishing environment building, perform the following operations: View the files included in current file system with the dir command:

<DEVICE>dir Directory of cf:/

0 -rw- 14323376 Apr 03 2006 15:36:48 main.bin 1 drw- - Mar 20 2006 09:55:28 logfile 2 -rw- 909 Apr 04 2006 10:54:38 configbak.cfg 3 -rw- 1045 Apr 04 2006 11:31:36 config.cfg 4 -rw- 14323376 Mar 31 2006 17:50:22 backup.bin

63340 KB total (20928 KB free)

File system type of cf: FAT32

Use the command as follows to backup the config.cfg file on the router to TFTP server and save as config.bak:

5-17

<DEVICE>tftp 192.168.0.1 put config.cfg config.bak File will be transferred in binary mode Sending file to remote tftp server. Please wait... \ TFTP: 1045 bytes sent in 0 second(s). File uploaded successfully.

Use this command to download the config.cfg file on the server to the router:

<DEVICE>tftp 192.168.0.1 get config.cfg config.cfg The file config.cfg exists. Overwrite it?[Y/N]:y Verifying server file... Deleting the old file, please wait... File will be transferred in binary mode Downloading file from remote tftp server, please wait...\ TFTP: 1045 bytes received in 0 second(s) File downloaded successfully.

If a config.cfg file already exists in the router, select <Y/y> to overwrite it.

z If a config.cfg file already exists on the server, it will be overwritten. z The above operations are performed under user view. z The backup configuration file can be modified by text editor. The configuration file modified during

download process can modify the configuration, and the modification takes effect after rebooting. Similarly, you can also download application program to the router to overwrite the old main program to upgrade the application program.

Maintaining the Router with FTP Server

Maintaining the router when it serves as the server

FTP (File Transfer Protocol) is an application layer protocol in the TCP/IP suit. It mainly transfers files among remote hosts. Born over TCP, it provides reliable and connection-oriente d data transfer service but does not provide access authorization and authentication mechanism.

The FTP service provided by the router is FTP Server , that is to say, the router serves as the FTP Server . You can run FTP Client to log onto the router and access files on the router.

Install FTP Client before using FTP. No FTP Server is available with the MSR 20 series. You must install one yourself. Take the FTP Client with Windows XP for example.

Step 1: Build hardware maintenan ce environment as follows:

5-18

Figure 5-9 Router maintenance when it serves as the server

Ethernet cable

Router

TFTP/FTP Server

Console cable

TFTP/FTP Client

Configure the IP addresses of the two sides to be in the same network. In this section, the PC server is set to 192.168.0.1, and the router Ethernet interface connected to it (Ethernet interface 0/0 in this example; so, any interface is OK) is set to 192.168.0.2. Both can use the ping command to check if the connection is successful.

Step 2: Boot FTP service. You can boot FTP service after configuring FTP server authentication and authorization. FTP server

supports multi-user access. The remote FTP user sends request to the FTP server, which then executes accordingly and returns the result of the execution to user . Use the following command to boot the FTP service:

[DEVICE]ftp server enable % Start FTP server

Add FTP authorized user name and password:

[DEVICE] local-user guest [DEVICE-luser- guest] service-type ftp [DEVICE-luser- guest] password simple 123456

Step 3: Maintain the router. After booting FTP service of the router and configuring user name and password, you can boot FTP

Client on your PC. Take the FTP Client with Windows XP for example: Enter <ftp> in the DOS window, and the system prompts:

C:\Documents and Settings\Administrator> ftp ftp> ftp> open 192.168.0.2 Connected to 192.168.0.2. 220 FTP service ready. User (192.168.0.2:(none)): guest 331 Password required for guest Password: 230 User logged in.

5-19

After you correctly enter the username and password, the system prompts login success, and you can complete maintenance of the router, for example, modifying transmission mode and local path, and backing up files. In this example, the main.bin file on the router is backed up to the PC.

ftp> binary 200 Type set to I. ftp> lcd c:\temp Local directory now C:\temp. ftp> get main.bin main.bin 200 Port command okay. 150 Opening BINARY mode data connection for main.bin. 226 Transfer complete. ftp: 14323376 bytes received in 16.81Seconds 851.87Kbytes/sec.

Recover the backup file to the router command:

ftp> put main.bin main.bin 200 Port command okay. 150 Opening BINARY mode data connection for main.bin. 226 Transfer complete. ftp: 14323376 bytes sent in 8.29Seconds 1727.37Kbytes/sec. ftp> quit 221 Server closing.

Maintaining the router when it serves as the client

You can also maintain the router file system by building FTP server and making the router serve as the client.

Step 1: Build maintenance environment as follows: Figure 5-10 Router maintenance when it serves as the client

When the router serves as the client, you can run FTP server program on your PC as the FTP server, and set the server path. Then, add user name and p assword for the router.

Configure the IP addresses of the two sides to be in the same network. In this section, the FTP server is set to 192.168.0.1, and the Ethernet interface connected to it (Ethernet interface 0/0 in this example; so,

5-20

any interface is OK) is set to 192.168.0.2. Both can use the ping command to check if the connection is successful.

Step 2: Maintain the router through the terminal connected to the console port as follow:

<DEVICE>ftp 192.168.0.1 Trying 192.168.0.1 ... Press CTRL+K to abort Connected to 192.168.0.1. 220 3Com 3CDaemon FTP Server Version 2.0 User(192.168.0.1:(none)): guest 331 User name ok, need password Password: 230 User logged in

[ftp]

Use the command as follows to maintain the router. Here, get and put commands are used to backup and recover files.

[ftp] get main.bin main.bin cf:/main.bin has been existing. Overwrite it?[Y/N]:y 200 PORT command successful. 150 File status OK ; about to open data connection 226 Closing data connection; File transfer successful. FTP: 14323376 byte(s) received in 69.256 second(s) 206.00K byte(s)/sec. [ftp]put main.bin main.bin 200 PORT command successful. 150 File status OK ; about to open data connection 226 Closing data connection; File transfer successful. FTP: 14323376 byte(s) sent in 15.974 second(s) 896.00Kbyte(s)/sec. [ftp]quit 221 Service closing control connection

Dealing with Router Password Loss

Do as follows when your BootROM password, user password or Super Passwo rd is lost.

User Password Loss

You cannot enter the system if you lose your user password. You can boot the system by neglecting system configuration. Perform the following operations:

Step 1: Enter the main BootROM menu, and sele ct <6 > to boot by ignoring system configuration: The system prompts:

........

Flag Set Successfully.

The system prompts set success. Step 2: When the main BootROM menu appears again, enter <a> to reboot the system.

........

system start booting......Version 2.11

Step 3: Set new password under the system view after rebooting.

[DEVICE] user-interface console 0 [DEVICE-ui-console0] authentication-mode password [DEVICE-ui-console0] set authentication password simple 123456

This indicates that the password authentication is adopted at the Console port and the password is set to 123456 and stored in plain text.

z After rebooting, the system runs with the initial default configuration. The original configuration files

are stored in memory. To restore the original configurations, you can use the display saved-configuration command to display them, and then copy and execute them.

z When storing the password in plain text, you can use the display current-configuration

command to see the password in the current configuration. If you use the set authentication password cipher 123456 command when setting the password, the password is encrypted and stored.

Step 4: Save the new configuration.

[DEVICE] save

Execute the save command after modifying the user password to save the new password.

5-24

BootROM Password Loss

Contact the agent or our technical su pport personnel in the event of BootROM passwo rd loss. They can help you set a new password

Modify the BootROM password under the main BootROM menu. Enter <5> to modify the password following the prompt. The console terminal displays:

Change password. Old password: New password: Verify:

........Password Set Successfully.

The password modification fails when old password is not correct or new password is not correctly entered, and then the system exits this operation.

Super Password Loss

The Super Password enables you to switch among the four Super levels. In the event of Super Password loss, you cannot perform the operations requiring higher right.

Enter <8> under the main BootROM menu to clear the Super Password. Select this option, quit the menu and reboot the router. You can directly enter the system view. Only

Memory bars are main board components that you can expand or upgrade as needed. Generally, you need to do that in the following situations:

z More memory is required for the updated application program, maintaining a large routing table, or

processing tasks that consume large memory.

z The existing memory bar is damaged.

6-5

z Hold the memory bar by its edge and avoid touching the components on its surface. An improper

operation might result in damage.

z It is normal that you feel hard when removing the memory bar, but do not overexert. z Use the memory bars provided by our company. only. Otherwise, anomalies might occur to the

device

7 Troubleshooting

Troubleshooting the Power System

Symptom:

The PWR LED on the PSU is OFF.

Solution:

Check that:

z The power switch on the router is turned on z The switch of the power source is turned on z The power cord is correctly connected z The power source meets the requirement of the router

Troubleshooting the Configuration System

If the router passes POST after powered on, the console screen displays the startup banner; if faults occur to the configuration system, the console screen displays nothing or only illegible characters.

Symptom 1: After the router is powered on, the console screen displays nothing. Solution: Step 1: Check that:

z The power system is normal. z The console cable is correctly connected.

Step 2: Check the console cable and the terminal (HyperTerminal for example) settings. Symptom 2: After the router is powered on, the console screen displays illegible characters. Solution: Verify that the terminal settings are as follows: Baud: 9600 Data bits: 8 Stop bit: 1 Parity: None Flow control: None Terminal emulation: VT100 Reconfigure the parameters if their values are differe nt.

Troubleshooting Application Software Upgrade

Symptom 1:

7-1

When upgrading the software using TFTP, the system displays:

boot device : motfcc unit number : 1 processor number : 0 file name : main.bin inet on ethernet (e) : 192.168.0.2 host inet (h) : 192.168.0.1 user (u) : guest ftp password (pw) : 123456 flags (f) : 0x80

Loading... Done! 0 bytes downloaded. Something wrong with the file.

Solution: Fault occurs because the source file does not exist, the network cable is not connected, or the IP

address of the PC is incorrect. Make sure that the source file is in the TFTP root directory, the cable is connected securely, and the IP address is set correctly.

Symptom 2: When upgrading the software using TFTP, the system displays:

Loading... Done! 11487495 bytes downloaded. Something wrong with the file.

Solution: Fault occurs because an incorrect application file is downloaded. Download the correct application

program file.

7-2

z The bar code labels on the chassis and the FICs contain information about production and

servicing. Before you ask your agent for servicing, provide its bar code.

z If you do not set the parameters such as the host name and gateway, they will not be displayed

when you upgrade the router. Therefore, the terminal display will be different from the above symptoms.
