About This Manual Organization H3C WX3000 Series Unified Switches Installation Manual is organized as follows: Chapter Chapter 1 Overview Contents Introduces the characteristics and appearance of the H3C WX3000 Series Unified Switches. [. . . ] After the basic BootWare section is started, you can download and update the extended BootWare through the menu of the basic BootWare section. Do not power off or restart the device when updating the BootWare program file; otherwise, the BootWare program may be damaged and the device may fail to operate normally. 5-1 Application Files The WX3000 series supports the Dual Image function. By default, the system defines three application files for system boot: Main application file (referred to as main file) Backup application file (referred to as backup file) Secure application file (referred to as secure file) These three application files are stored in the flash memory, with the file name extension of . bin. Typically, the default application files are written into the built-in flash memory before device delivery. If you have uploaded all the three types of application files in the flash memory, the system uses these three files to boot the device in the sequence of main. bin, backup. bin, and secure. bin. For how to set the type of an application file, refer to section Maintaining the Application and Configuration Files on page 5-22. The following gives the default names and types of the application files and their priorities for booting: Main application file. If the system fails to boot using the main application file, it tries the backup application file. If the system fails to boot using the backup application file, it tries the secure application files. If the system fails to boot using the secure file, it gives a startup failure message. Note that: Only the application files of the M, B, and S types can be used to boot the system, while an application file of the N type (an application file other than the M, B, or S type) cannot. You can rename the application files in the flash memory through the command line interface (CLI) after the application program is loaded. You can modify the file type of the M, B, and N types application files through the BootWare menu or the CLI after application startup, while you cannot modify the file type of the S-type application file. The secure application file is the last resort for system boot; therefore, you cannot change the file type of the secure application file or turn another type of file into a secure file by modifying the file type. Only one file of the same type (M, B, or S) can exist in the flash memory at a time. For example, if an application file of type M+B exists in the CF card, another file of type M or B cannot exist. If the type of another file is changed to B, the existing type M+B file changes to a file of type M. Configuration Files With the file name extension of . cfg, configuration files are used to store the configuration information of the device. Typically, no configuration file with the name extension . cfg is provided when the device is delivered (a configuration file with name extension . def is provided by the switching engine). If the configuration file is deleted or missing, the device also loads the default configuration at reboot. The access control engine has only one configuration file with no backup. The switching engine has main and backup configuration files, which are managed like the application files on the access control engine. 5-2 The length of a configuration file name must not exceed 64 characters (including the drive identifier and the string terminator). For example, if the drive identifier is flash: /, the maximum length of a file name is [ 64 ­ 1 ­ 5 ] = 58 characters. If the length of a file name exceeds 58 characters, operations on that file will fail. [. . . ] Otherwise, it means that the power receptacle of the arrester is set to the reverse polarity. In this case, open the power receptacle of the arrester and correct the polarity. After that, if the red LED still alarms, it means that the arrester is not well grounded yet.
