Barracuda Link Balancer

Reloading, Restarting, and Shutting Down the System

  • Last updated on

This article describes the shutdown, reboot and reload functions of the Barracuda Link Balancer and explains how to use the recovery console in case of system failure.

CAUTION! Use of these controls temporarily interrupts all Barracuda Link Balancer operations.

Shutting Down and Restarting the System

To shut down, restart, or reload the system configuration of your Barracuda Link Balancer:

  1. Go to the BASIC > Administration page.
  2. In the System Reload/Shutdown section at the bottom, select the desired option:
    • Shutdown - Shuts down and powers OFF the Barracuda Link Balancer.
    • Restart - Reboots the Barracuda Link Balancer.
    • Reload - Reapplies the system configuration.

You can also reboot the Barracuda Link Balancer by pressing RESET on the front panel of the Barracuda Link Balancer. Do not press and hold the RESET button for more than a couple of seconds. Holding it for five seconds or longer changes the IP address of the system. For more information, see Using the RESET Button to Reset the LAN IP Address.

Rebooting the System in Recovery Mode

If your Barracuda Link Balancer experiences a serious issue that impacts its core functionality, you can use diagnostic and recovery tools, available at the reboot menu, to return your system to an operational state. Before you use the diagnostic and recovery tools, do the following:

As a last resort, you can reboot your Barracuda Link Balancer and run a memory test or perform a complete system recovery, as described in this section. To perform a system recovery or hardware test:

  1. Connect a monitor and keyboard directly to your Barracuda Link Balancer.
  2. Reboot the system by clicking Restart on the BASIC > Administration page. 
  3. Press the Power button on the front panel to power the system off, and then press Power again to power the system back on. The Barracuda splash screen displays with three reboot options explained below.
  4. Use your keyboard to select the desired boot option, and click Enter. You must select the boot option within three seconds of the splash screen appearing or the Barracuda Link Balancer defaults starts up in the normal mode (first option).

Reboot Options

The following table describes the reboot menu options.

Reboot OptionDescription

Barracuda

Starts the Barracuda Link Balancer in the normal (default) mode. This option is the default unless another option is specified within the first three (3) seconds of the splash screen appearing.

Recovery

Displays the Recovery Console where you can choose among the following options:

  • Perform file system repair - Repairs the file system on the Barracuda Link Balancer.
  • Perform full system re-image - Restores the factory settings on your Barracuda Link Balancer and clears out all configuration information.
  • Enable remote administration - Initiates a connection to Barracuda Central that allows Barracuda Networks Technical Support to access the system. Another method for enabling this troubleshooting connection is to click Establish Connection to Barracuda Central on the ADVANCED > Troubleshooting page.
  • Run diagnostic memory test - Runs a diagnostic memory test from the operating system. If problems are reported when running this option, we recommend running the Hardware_Test option next.

Hardware_Test

Performs a thorough memory test that uncovers most memory related errors within a two-hour time period. The memory test is performed outside of the operating system and can take a long time to complete. Reboot your  Barracuda Link Balancer to stop the hardware test. You may do this by pressing Ctrl-Alt-Del on the keyboard, or by pressing the RESET button on the Barracuda Link Balancer.

 

Using the RESET Button to Reset the LAN IP Address

The Barracuda Link Balancer is assigned a default LAN IP address of 192.168.200.200. You can change this IP address in one of three ways:

  • In the web interface, go to the BASIC > IP Configuration page.
  • Connect a VGA monitor and a keyboard to the back of the Barracuda Link Balancer. Use the serial console. (username admin, password admin)
  • Press the RESET button on the front panel.

Pressing RESET for five seconds sets the LAN IP address to 192.168.200.200. Pressing RESET for eight seconds changes the LAN IP address to 192.168.1.200. Pressing the button for 12 seconds changes the LAN IP address to 10.1.1.200. You will notice the three LEDs on the front panel flash at the same time intervals.
