Modifying the Boot Configuration Chapter 1 Setting Up the ACE Configuring the ACE to Bypass the Startup Configuration File During the Boot Process From the GRUB bootloader, the ACE includes an option that allows you to instruct the ACE to bypass the startup-configuration file stored on the appliance in the Flash memory (nonvolatile memory) during the boot process. You may require the ACE to bypass the startup configuration file during bootup in the following instances: • Certain configurations cause problems that result in the ACE becoming nonresponsive. You can bypass the startup configuration file to safely boot the ACE and then resolve issues with the configuration. • You forget the password for the ACE administrator CLI account and cannot access the ACE. You can bypass the startup configuration file and log in with the default password of admin. Note For the procedure on resetting the administrator CLI account password, see the "Resetting the Administrator CLI Account Password" section. To instruct the ACE to bypass the startup-configuration file during the boot process from the GRUB bootloader, perform the following steps: 1. Enter the config-register command so that upon reboot the ACE boots to the GRUB bootloader. See the "Setting the Boot Method from the Configuration Register" section. 2. Reboot the ACE. See the "Restarting the ACE" section. Upon reboot, the ACE boots to the GRUB bootloader. 1-38 Cisco 4700 Series Application Control Engine Appliance Administration Guide OL-11157-01
