BootROM Menu

BootROM Menu

The Boot Read-Only Memory (BootROM) is a set of programs fixed in the read-only memory (ROM) chip on a device's main card. The BootROM contains the basic input/output program, system settings, power on self-test (POST) program, and system self-startup program.

The BootROM program on the device composed of two menus:
  • BootROM main menu: is the main menu of the BootROM. During the device startup, press Ctrl+B or Ctrl+E to access this menu. The BootROM main menu provides rich functions including file transfer, startup file configuration, file management, and change on BootROM and console port passwords.
  • DIAG menu: You can enter this menu by pressing Ctrl+E in the BootROM main menu. This menu is used for equipment commissioning during the device production and assembly process. You are advised to use this menu under the supervision of technical support personnel. This manual does not provide description about this menu. For details, see S1720, S2700, S5700, and S6720 Series Ethernet Switches Troubleshooting.
If the device properly starts, accessing the BootROM menu is not necessary. If either of the following situations occurs, you can use the BootROM menu to:
  • Restore or upgrade the system when the system stops responding and the command line interface (CLI) cannot be displayed.
  • Delete the password for logging in to the device using the console port when you forget the password.

The BootROM menu also allows you to back up the configuration file, format the storage device, and change the BootROM password.

  • Only the S1720GFR, S2750EI, S5700LI, S5700S-LI (excluding S5700S-28X-LI-AC and S5700S-52X-LI-AC) support the BootROM menu.
  • To view the device startup process, log in to the device using the console port. Press shortcut keys as prompted to access a BootROM menu. For the method of login using the console port, see Configuring Login Through a Console Port. Access the equipment menu from the BootROM main menu. No option or message is provided, so you must remember the shortcut keys.

  • Do not power off the device while managing the device using the BootROM; otherwise, the settings in the BootROM menu are lost.
  • The screen display information varies depending on devices.
