2 Installation Preparation

Safety Precautions

To avoid any device impairment and bodily injury caused by improper use, observe these rules:

z Pull the power plug(s) out of the AC before cleaning the AC. Do not clean the AC using wet cloth or

liquid.

z Keep the AC away from water or dampness. Prevent water or moisture from entering the AC

chassis.

z Do not place the AC on an unstable case or desk. The switch might be damaged severely in case

of a fall.

z Ensure proper ventilation in the equipment room and keep the vents of the AC free of obstruction.

z Make sure that the operating voltage is within the range labeled on the AC.

z Do not open the chassis when the AC is operating or when electrical hazards are present to avoid

electrical shocks.

z When replacing interface cards, wear ESD-preventive gloves to avoid damaging the cards.

Installation Site Checking

The WX5002 AC must be used indoors. You can mount a AC in a cabinet or on a workbench, but make

sure that:

z Adequate clearances are reserved at the air inlet/exhaust vents for heat dissipation.

z The cabinet or workbench has a good ventilation system.

z The cabinet is sturdy enough to support the AC and its accessories.

z The cabinet or workbench is well earthed.

To ensure normal operation and a long service life of your AC, install it in an environment that meets the

requirements described in the following subsections.

Requirements on Temperature/Humidity

You must maintain a proper temperature and humidity in the equipment room. A long term of high

humidity may lead to bad insulation, electricity leakage, mechanical property changes, and corrosion.

However, if the relative humidity is too low, captive screws may become loose as a result of contraction

of insulation washers and static electricity may be produced in a dry environment to jeopardize the

circuits on the device. A high temperature is the most undesirable condition, because it accelerates the

aging of insulation materials and thus significantly lowers the reliability and service life of the AC.

Requirements on Cleanness

Dust is a hazard to the operating safety of the AC. The dust accumulated on the chassis can be

adsorbed by static electricity and result in poor contact of metal connectors or metal contact points.

Especially, when the relative indoor humidity is low, electrostatic adsorption is more likely to happen.

This can not only shorten the service life of the AC but also cause communications failures. The

following table lists the dust concentration limit.

2-1

Table 2-1 Dust concentration limit in the equipment room

Physical active substance Concentration limit (particles/m3)

Dust

Note: The dust particle diameter is ≥ 5 μm

≤ 3 × 104 (No visible dust on the tabletop over three days)

Besides the dust requirements, the AC equipment room also needs to strictly meet the requirements on

the concentration of salt, acid, and sulfide. These harmful gases can accelerate the metallic corrosion

and the aging process of some parts. The specific limits of the harmful gases such as SO

and CI2 are given in the following table.

Table 2-2 Limit on harmful gases in the equipment room

Gas Maximum concentration (mg/m3)

SO2 0.2

H2S 0.006

NH3 0.05

Cl2 0.01

Requirements on Electromagnetic Susceptibility

, H2S, NO2,

The operation of your AC may be affected by external interferences, such as capacitance coupling,

inductance coupling, electromagnetic wave radiation, common impedance (including the grounding

system) coupling, and the conducted interference of leads (power cords, signaling cables and output

wires). To eliminate the interferences,

z For the AC power supply that adopts the TN system, use a single-phase three-wire power socket

with a protection earth (PE) to effectively filter interference from the power grid.

z Keep the AC away from high-power radio transmitters, radars, and high-frequency heavy-current

devices.

z Use electromagnetic shielding measures when necessary. For example, use shielded interface

cables.

z Route interface cables only indoors to prevent signal interfaces from getting damaged by

over-voltage or over-current caused by lightning strikes.

Laser Safety

WX5002 AC are Class 1 laser devices.

When the optional optical interfaces on a WX5002 AC are operating, avoid staring into the optical

interfaces because the high-energy laser beam emitted from the optical fiber may hurt your retina.

z Phillips screwdriver

z ESD-preventive wrist strap

The installation tools are not provided with WX5002 AC. You need to prepare them yourself.

3 Installation

When you ask your sales agent to maintain your AC, you must ensure that the

dismantlement-preventive seal on a mounting screw of the AC chassis is intact. If you want to open the

chassis, you should contact the agent for permission. Otherwise, you will bear any consequence

resulting from your actions.

Installation Procedure

Installing a AC onto a 19-Inch Rack

Follow these steps to mount the AC onto a standard 19-inch rack:

Step 1: Check that the rack is sturdy and properly earthed. Attach a mounting ear to both sides of the

AC front panel with screws.

Step 2: Place the AC on a tray and slide it to a proper position along the guide rails, reserving a suitable

clearance between the AC and the guide rails.

Step 3: Fix the mounting ears to the square-holed brackets with screws and make sure that the AC is

fixed horizontally and securely.

Figure 3-1 Install a AC onto a 19-inch rack

Installing a front mounting ear

The following figures illustrate the installation of a front mounting ear:

Figure 3-2 Install a front mounting ear onto a AC

Figure 3-3 Install a front mounting ear onto a square-holed bracket

Installing a AC on a Workbench

In many cases, standard 19-inch racks are not available to users and ACs are often installed on clean

workbenches. When installing an AC on a workbench,

z Make sure that the workbench is flat, sturdy and well earthed.

z Keep the environment well ventilated and reserve a clearance of 10 cm (3.9 in.) around the chassis

for heat dissipation.

z Place no heavy objects on the AC.

z Keep at least a vertical distance of 1.5 cm (0.59 in.) between ACs in the case of stack application.

3-2

Power Cords and Ground Wire Connection

Connecting the AC Power Cord

AC power socket (recommended)

You are recommended to use a single-phase three-wire power socket with a neural point or a

multifunction PC socket. The neutral point of the power in the building must be well grounded. Usually,

the neutral points of power supplies in buildings are already grounded during cabling. Still, you need to

check that the power supply of the building is reliably grounded.

Connecting the AC power cord

Step 1: Connect one end of the ground wire (delivered with the AC) to the grounding terminal on the rear

panel of the chassis and the other end to the near ground.

Step 2: Connect one end of the power cord to either power socket on the rear panel of the chassis, and

the other end to the power supply.

Step 3: Install the power cord retainer for the AC power cord. Insert the two ends of the power cord

retainer into the slots on both sides of the AC power socket, and then set the power cord into the notch

of the power cord retainer.

Figure 3-4 Install the AC power cord retainer

(1) Rear panel of the AC (2) Power cord retainer slots (3) AC power cord retainer (4) AC power cord

z The AC power cord retainer can prevent the AC power cord from falling off.

z Whether a power cord retainer is needed depends on the power supply system of the country.

Step 4: Check whether the corresponding PWR LED on the front panel of the AC is ON. If the LED is ON,

the power cord is properly connected.

Make sure that the ground wire is properly connected before powering on the AC.

3-3

Connecting the Ground Wire

Connect the AC ground wire properly since it is crucial to lightning protection and electromagnetic

susceptibility (EMS).

The power input end of the AC is connected with a noise filter, whose central ground is directly

connected to the chassis, forming the chassis ground (also known as PGND). This chassis ground must

be securely grounded so that induced and leaked electricity can be safely discharged to the ground,

enhancing the EMS capability of the AC. Ground the AC as follows:

z When a grounding strip is available, attach one end of the yellow-green ground wire of the AC to

the grounding terminal on the grounding strip and fasten the captive nut. Note that the fire main and

lightning rod of a building are not suitable for grounding the AC. The ground wire of the AC should

be connected to the grounding device in the equipment room.

Figure 3-5 Ground the AC through a grounding strip

(1) AC power socket (2) Grounding terminal (3) Protection ground wire (4) Grounding strip

z When there is no grounding strip but earth is available nearby and allows a grounding body to be

buried, hammer an angle steel or steel pipe longer than 0.5 m (1.64 ft) into the earth. In this case,

weld the yellow-green ground wire of the AC onto the angle steel or steel pipe, and treat the joint for

corrosion protection.

3-4

Figure 3-6 Ground the AC by burying a grounding body into the earth

z For an AC-powered AC, if neither of the above-mentioned two conditions is available, ground the

AC through a PE wire of the AC power supply. In this case, make sure the PE wire is well

Connecting the Console Cable

Follow these steps to connect a terminal device, a PC for example, to the AC:

Step 1: Plug the DB-9 female connector of the console cable to the serial interface of the PC or terminal

where the AC is to be configured.

Step 2: Connect the RJ-45 connector of the console cable to the console interface of the AC.

Pay attention to the interface mark and plug the connector to the right interface.

For a powered-on AC:

z When connecting a PC to the AC, you are recommended to first connect the DB-9 connector of the

console cable to the PC, and then the RJ-45 connector to the console interface of the AC.

z When disconnecting a PC from the AC, you are recommended to first disconnect the RJ-45

connector, and then the DB-9 connector.

Gigabit Ethernet Interface Connection

A WX5002 AC provides two gigabit Ethernet combo interfaces on its front panel. The connection

methods of the gigabit Ethernet electrical interface and the gigabit Ethernet optical interface are

respectively described here.

Connecting an Ethernet Electrical Interface

Cables for connecting an Ethernet electrical interface

Ethernet electrical interfaces usually use category 5 twisted pair cables, as shown in Figure 3-9.

Figure 3-9 Ethernet cable

Ethernet cables fall into the following categories:

z Standard cable, also called straight-through cable. At both ends of the cable, wires are crimped in

the RJ-45 connectors in the same sequence. Such a cable is used to connect a terminal device

(PC and AC for example) to a hub or LAN Switch.

z Crossover cable. Wires are crimped in the RJ-45 connectors in different sequences at the two ends

of the cable. Such a cable is used to connect a terminal device (PC and AC for example) to a

terminal device. You can make crossover cables yourself as needed.

In making network cables, shielded cables are preferred for electromagnetic compatibility sake.

Electrical interface connection procedure

If you connect a twisted-pair cable to a 10/100/1000 Mbps Ethernet electrical interface and an optical

fiber to a 10/100/1000 Mbps Ethernet optical interface as well, the system considers the electrical

interface as the working interface by default.

Step 1: Connect one end of the Ethernet cable to an Ethernet electrical interface and the other end to

the peer device.

z A 10/100/1000 Mbps Ethernet interface supports MDI/MDIX auto-sensing. Therefore you can use

a crossover cable or a straight-through cable to connect the interface to a hub or LAN Switch.

3-7

Step 2: View the LED of the Ethernet interface. ON means a link is present. OFF means no link is

present. If the LED is OFF, check the line for the cause.

Connecting an Ethernet Optical Interface

Cables for connecting an Ethernet optical interface

For 10/100/1000 Mbps Ethernet optical interfaces, use single-mode or multi-mode optical fibers to

connect to the Ethernet based on the type of the installed 1000 Base-SX/LX SFP modules. As the

optical interfaces of these SFP modules use LC-type fiber-optic connectors, you must use fibers with

LC-type connectors for them. All these SFP modules are hot swappable.

Optical interface connection procedure

When connecting optical fibers, make sure that:

z The curvature radius of fibers is no less than 10 cm (3.9 in.).

z The Tx and Rx connectors are correctly connected.

z The fiber ends are clean.

Laser is dangerous! To protect your eyes against radiation harm, never stare into an optical fiber

connector directly.

Step 1: Put on an ESD-preventive wrist strap and make sure that the ESD-preventive wrist strap is

properly grounded. Then take the SFP module out of the package.

Step 2: Remove the optical module filler plug from the shielding hood of the optical interfaces of the AC.

Step 3: Hold the SFP module and slide the SFP module along the optical interface shielding hood gently

until the SFP module makes skin contact with the AC.

Step 4: Distinguish between the Rx and Tx interfaces. Connect one end of an optical fiber to the Rx

interface of the AC and the other end to the Tx interface of the peer device. Use another fiber to connect

the AC and the peer device in the opposite way.

Step 5: Power on the AC and check the 1000 Mbps LED of the 10M/100M/1000M Ethernet interface.

ON means the Rx link is present. OFF means no Rx link is present. If the LED is OFF, check the line for

the cause.

Installation Verification

After installation, make sure that:

z The correct power supply is used.

z The ground wire is securely connected.

z Both the console cable and power cord are correctly connected.

3-8

z All interface cables are routed indoors. If there are cables outdoors, check that a AC power strip

with lightning protection and lightning arresters for network interfaces have been correctly

connected.

5 AC Software Maintenance

Overview

Files Managed by the AC

BootWare program file

The file is used to boot applications when the AC is started up. A complete BootWare program file

includes two segments: basic and extended.

Application file

WX5002 AC support the Dual Image function. By default, the system defines three application files for

booting: main, backup, and secure. If you have loaded the three application files into the Flash, the

system will use these three files to boot in order. For more information about the application files, refer

to section “

Maintaining Application and Configuration Files in BootWare” on page 5-18.

The following gives the default names and types of the application files and their priorities for booting.

z Main application file. The default name is main.bin, and the file type is M. It is the default application

file used for booting.

z Backup application file. The default name is backup.bin, and the file type is B. When the boot using

the main application file fails, the system boots using the backup application file.

z Secure application file. The default name is secure.bin, and the file type is S. When boot using the

backup application file fails, the system boots using the secure application file. If the boot using the

secure application file fails, the system prompts a boot failure.

z The application files for system boot can be type M, B and S, but not type N/A (that is, types other

than M, B, and S).

z You can modify the names of application files of type M, B and N/A except type S in the BootWare

menu or using commands after the application program boots.

z The secure application file is the last resort for system boot. You cannot change the type of the

secure application file, or change other types of files to the secure application file. You can only

download it using the BootWare menu. If you change the name of the secure application file with

the rename command after the system boots, the file is removed from the Flash. To use the secure

application file, you need to download it again.

z There is only one file of the same type (M, B, or S) in the Flash. For instance, if there is a file of type

M+B in the Flash, there will not be other files of type M or B. If the type of another file is changed to

B, the original type M+B file changes to a file of type M.

5-1

Configuration file

The file stores configuration information of the AC.

AC Software Maintenance Methods

z Upgrade BootWare and application programs using XMODEM protocol through a serial interface.

z Upgrading application programs from TFTP server through Ethernet interface in BootWare.

z Upload/download application programs and configuration files to/from the TFTP/FTP server

through command lines.

z The BootWare program is upgraded together with the host software program version. That is, the

system automatically upgrades the BootWare program when you upgrade the host software program.

z Check the current version of BootWare and application programs before upgrading. For the

association between the host software program version and the BootWare program version, refer

to the version configuration information in Release Notes.

Upgrading BootWare Through a Serial Interface

Use XMODEM to upgrade BootWare through a serial interface.

Modifying Serial Interface Parameters

Sometimes, we need to make the serial interface baud rate higher to save upgrading time or make it

lower to guarantee transmission reliability. This section introduces how to adjust the serial interface

baud rate.

Enter the BootWare main menu and select 2 to enter the serial interface submenu, and then select 5 in

the submenu to modify the baud rate. The system displays the following:

========================<BAUDRATE SET>======================= |Note: Change The HyperTerminal's Baudrate Accordingly, | | Press 'Enter' to exit with things untouched. | |--------------------<Baudrate Avaliable>-------------------| | <1> 9600(Default) | | <2> 19200 | | <3> 38400 | | <4> 57600 | | <5> 115200 | | <0> Exit | ============================================================= Enter Your Choice (0-5):

Select a proper baud rate. For example, select 5 for a baud rate of 115,200 bps and the system displays

the following information:

Download speed is 115200 bps. Change the terminal's speed to 115200 bps, and select XMODEM protocol. Press 'Enter' key when ready.

At this time, the baud rate of the AC serial interface is modified to 115,200 bps, while that of the terminal

is still 9,600 bps. The AC and the terminal cannot communicate with each other. Change the baud rate

to 115,200 bps on the terminal.

Perform the following operations on the terminal:

“

Configuring Ethernet Interface Parameters

Before upgrading an application program through an Ethernet interface, you need to configure the

Ethernet interface of the AC as follows:

Select 3 in the BootWare main menu to enter the Ethernet submenu. Then, select 5 in the submenu to

enter the Ethernet interface parameter configuration interface:

5-11

One protocol for download, tftp. '.' = clear field; '-' = go to previous field; ^D = quit boot device : eth0 Boot device name. Cannot be changed. file name : wx5002.bin The download file name shall be consistentwith the real file name, and you need to designate the download path in TFTP settings. inet on ethernet (e) : 192.168.0.124 Set to be in the same network with TFTP server. It has nothing to do with port IP address of the AC. host inet (h) : 192.168.0.179 IP address of TFTP server. gateway inet (g) : 192.168.0.1 Gateway IP address. No need to set.

z When configuring a parameter, you can enter a new value directly, or press Enter to accept the

default coming after the colon. Type the symbol “.” to clear the input, “-” to return to the previous

parameter, and “^D” (namely, <Ctrl+D>) to quit from the parameter configuration interface.

z WX5002 AC can use the 10/100 BASE-TX out-of-band management interface only.

Upgrading an Application Program

Trivial File Transfer Protocol (TFTP), a protocol in TCP/IP protocol suite, is used for trivial file transfer

between client and server. It provides not-so-complex and low-cost file transfer services. TFTP provides

unreliable data transfer services over UDP and does not provide any access authorization and

authentication mechanism. It employs timeout and retransmission to guarantee the successful delivery

of data. The TFTP software is much smaller than the FTP software in size.

Step 1: Set up an upgrade environment.

Figure 5-7 Set up a TFTP upgrade environment

Connect the 10/100 BASE-TX out-of-band management interface to a PC with a crossover cable. Start

the TFTP server on the PC, and set the TFTP server path to the directory of the application program.

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

No enough space in flash! Writing into Flash Fails.

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

file. In this example, the downloaded file main.bin replaces the original type M file and becomes the

main application file.

z Refer to section “Files Managed by the AC” on page 5-1 for detailed descriptions on file types.

Maintaining Application Programs and Configurations Through Command Lines

After booting the AC normally, you can upgrade/back up application programs and back up/restore

configurations through command lines.

5-13

Maintaining the AC Through the TFTP Server

In the TFTP service, H3C WX5002 AC serve as TFTP clients, while the file server serves as the TFTP

server. You can enter commands on the PC to upload or download configuration files and application

programs of the AC to or from the file server.

Setting up a configuration environment

First, set up a hardware environment (for the procedure, refer to section “Upgrading an Application

Program” on page

Figure 5-8 Network diagram for maintenance through command lines

5-12), and point the server path to the directory where the file is stored.

Configure the IP addresses of the two sides on the same network. For example, the IP address of the

TFTP server is set to 192.168.0.1, and that of the AC is set to 192.168.0.2. Use the ping command on

the TFTP server or AC to check whether the connection is successful.

Backing up and restoring application programs and configuration files

After setting up the environment, perform the following operations on the PC:

View the files included in the current file system with the dir command.

<H3C>dir Directory of flash:/

Use the following command to upload the startup.cfg file from the AC to the TFTP server and save it as

startup.bak.

<H3C>tftp 192.168.0.1 put startup.cfg startup.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 the following command to download the startup.cfg file from the server to the AC.

5-14

<H3C>tftp 192.168.0.1 get startup.cfg startup.cfg The file startup.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 there already exists a startup.cfg file on the AC, the system prompts you whether to overwrite it. You

can enter Y or N to confirm.

z When you back up a file, the file will directly overwrite the one with the same name on the server.

z The above operations are performed in user view.

z The backup configuration file can be modified by a text editor. You can modify the configurations by

downloading the modified configuration file, and the modification takes effect after rebooting. Alike,

you can upgrade the main application file by downloading a new application file to the AC to

overwrite the original main application file.

Maintaining the AC Through the FTP Server

Maintaining the AC acting as the server

File Transfer Protocol (FTP) is an application layer protocol in the TCP/IP suite. It is mainly used for file

transfer between remote hosts. FTP provides reliable and connection-oriented data transfer service

over TCP, but does not provide any access authorization or authentication mechanism.

In the FTP service, the AC can serve as the FTP server. You can run the FTP client to log in to the AC to

access files.

Install the FTP client application before using FTP. The FTP client application is not provided with the

AC, and you need to purchase and install it. In the following example, the FTP client application

program is the built-in Windows XP FTP client:

Step 1: Set up a hardware maintenance environment as follows:

Figure 5-9 Network diagram for maintenance of the AC serving as the server

5-15

Configure the IP addresses of the two sides on the same network. In this section, the IP address of the

FTP client (PC) is set to 192.168.0.1, while that of the AC is set to 192.168.0.2. You can use the ping

command on the PC or AC to check whether the connection is successful.

Step 2: Enable the FTP service.

You can enable the FTP service after configuring FTP server authentication and authorization. The FTP

server supports multi-client access. A remote FTP client sends a request to the FTP server. The FTP

server executes an action accordingly and returns the execution result to the client. Use the following

command to enable the FTP service.

[H3C]ftp server enable % Start FTP server

Add an authorized FTP username and password.

[H3C]local-user guest Add the username guest [H3C-luser- guest]service-type ftp Set the client type to FTP. [H3C-luser- guest]password simple 123456 Add the password 123456 for the user guest [H3C-luser-guest]authorization-attribute level 3 Set the user level to 3

Step 3: Maintain the AC.

After enabling the FTP service and configuring the username and password, you can enable FTP client

on the PC. In the following example, the FTP client application program is the built-in Windows XP FTP

client.

Type ftp in the DOS window, and the system prompt is changed to ftp>:

C:\Documents and Settings\Administrator>ftp ftp> The system prompt is changed to ftp> ftp> open 192.168.0.2 Connect to the AC IP address Connected to 192.168.0.2. 220 FTP service ready. User (192.168.0.2:(none)): guest Enter the usrname guest on the AC 331 Password required for guest Password: Enter the password 123456 230 User logged in. The connection to the server succeeded.

Now, use the following commands to maintain the AC. In this example, the main.bin file on the AC is

copied to the PC.

ftp> binary Change the transfer mode to binary 200 Type set to I. ftp> lcd c:\temp Change the local path Local directory now C:\temp. ftp> get main.bin main.bin Copy the file from the AC to the PC 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.

Use the following command to overwrite the main.bin file on the AC.

ftp> put main.bin main.bin Overwrite the file on the AC with the local backup file. 200 Port command okay. 150 Opening BINARY mode data connection for main.bin.

5-16

226 Transfer complete. ftp: 14323376 bytes sent in 8.29Seconds 1727.37Kbytes/sec. ftp> quit Quit FTP 221 Server closing.

Maintaining the AC acting as the client

You can also maintain the AC file system by setting up an FTP environment where the AC serves as a

client.

Step 1: Set up a maintenance environment.

Figure 5-10 Network diagram for maintenance of the AC serving as a client

The AC serves as an FTP client, while the PC running FTP server serves as the FTP server. Set the

FTP server path and add a username and password for the AC.

Configure the IP addresses of the two sides on the same network. In this section, the IP address of the

FTP server is set to 192.168.0.1, and that of the AC is set to 192.168.0.2. You can use the ping

command on the server or the AC to check whether the connection is successful.

Step 2: Maintain the AC through the terminal connected to the console interface of the AC.

The following gives an example:

<H3C>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 Enter the username configured on the server 331 User name ok, need password Password: Enter the corresponding password 230 User logged in Connection succeeded. [ftp]

Use the following commands to maintain the AC after logging in.

Here again, the get and put commands are used to restore and back up files.

[ftp]get main.bin main.bin Download the file from th e server to the AC flash:/main.bin has been existing. Overwrite it?[Y/N]:y Overwrite the file 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 Copy the file from the AC to the server

5-17

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 Quit FTP 221 Service closing control connection

Dealing With Password Loss

When the BootWare password, user password or super password is lost, resort to the following

methods:

User Password Loss

If you lose your password, you cannot enter the system. In this case, you can boot the system by

neglecting the system configuration. Perform the following operations:

Step 1: Enter the BootWare main menu, and select 6 to boot the system by ignoring the system

configuration:

The system prompts:

System startup with ignore user's configuration, Yes or No [Y/N]:y Flag Set Successfully!

5-19

The system prompts the setting succeeds.

Step 2: When the BootWare main menu appears again, select 0 to reboot the system.

System starts booting ...

Step 3: Set a new password in system view after reboot.

[H3C]user-interface con 0 [H3C-ui-aux0]authentication-mode password [H3C-ui-aux0]set authentication password simple 123456

The above information indicates that the password authentication is adopted at the console interface

and the password is set to 123456 and stored in plain text.

z After reboot, the system runs with the initial default configuration, but the original configuration file

is still stored in the Flash. To restore the original configuration, you can use the display saved-configuration command to display it, and then copy and execute it.

z If the password is stored in plain text, you can use the display current-configuration command to

see the password in the current configuration. If you use the set au thentication pass word cipher 123456 command to set a password, the password is stored in cipher text.

Step 4: Save the new password.

[H3C] save

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

BootWare Password Loss

Contact the agent or the technical support personnel to set a new password in the event of BootWare

password loss.

You can modify the BootWare password in the BootWare main menu.

Select 5 in the BootWare main menu to modify the password. The console terminal displays:

Change password. Old password: Enter the old password New password: Enter a new password Verify: Enter the new password again

........Password Set Successfully. The new password is set successfully

5-20

The password modification fails when the old password is incorrect or the new password is inconsistent,

and the system will exit this operation.

Super Password Loss

The super password enables you to switch between four super levels. In the case of super password

loss, you cannot perform higher level operations.

You can clear the super password by selecting 8 in the BootWare main menu.

Select this option, quit the menu, and reboot the AC, and then you can enter system view directly. This

setting is valid for the first reboot of the AC only. The super password will be restored after a second

reboot.

Backing Up and Restoring BootWare

6 Maintenance and Troubleshooting

Software Loading Failure

If software loading fails, the system still runs the original version. In this case, check whether the

physical interfaces are properly connected:

z If not, reconnect them correctly and restart the loading procedure.

z If so, view the loading information displayed on the HyperTerminal to check for input errors. If there

is any input error, restart the loading procedure and ensure the input correctness.

Common input errors include:

z Fail to set the baud rate of the HyperTerminal to 9,600 bps when loading the software at a baud

rate of 9,600 bps through XMODEM.

z Enter an incorrect IP address, software name, or path of the TFTP server when using TFTP.

z Enter an incorrect IP address, software name, username, or password when using FTP.

If software loading fails when there are neither physical connection problems nor input errors, please

contact your agent for help.

Power Supply Failure

You can check whether the AC power system works normally by observing the PWR LED on the front

panel. The PWR LED is ON when the power system works normally. When the PWR LED is OFF, check

whether:

z The AC power cord is properly connected.

z The AC power supply meets the requirement.

Configuration System Failure

After the AC is powered on and the system is normal, the booting information will be displayed on the

console terminal. If the configuration system has any faults, illegible characters or nothing will be

displayed on the console terminal.

Troubleshooting when nothing is displayed

If nothing is displayed on the terminal after the AC is powered on, please check whether:

z The power supply is normal.

z The console cable is properly connected.

If the above-mentioned items ruled out, the problem may lie in the console cable or the settings of the

terminal (such as HyperTerminal) parameters. Please perform the corresponding check.

Troubleshooting when illegible characters are displayed on the terminal

If illegible characters are displayed at the console terminal, the problem probably lies in the parameter

settings on the terminal (such as HyperTerminal). Verify the following terminal parameter (such as

HyperTerminal) settings:

6-1

z Bits per second: 9600

z Data bits: 8

z Parity: None

z Stop bits: 1

z Flow control: None

z Emulation: VT100.
