The hardware specifications list was valid at the time this manual was published. The listed components are subject to change at any time, as Barracuda Networks may change hardware components due to technological advancements. Therefore, the list may not reflect the current hardware configuration of the Barracuda appliance it was delivered with.

Status LEDs and Acoustic Signals

Your appliance is equipped with a variety of LEDs. One of them is the Status LED. It is labeled either with a heart symbol or the term Status. It indicates the appliance’s operational state by changing colors between green, orange, and red and by changing between blinking and steady glowing. The table below shows the different meanings:

Color Status Meaning installation Meaning Normal Operation or Active Recovery Technology Operation
Off Off

Appliance is powered off or installation has not initialized far enough for LED control when installation is started.

Appliance is powered off.
Green Blinking Normal installation.

Appliance is either booting, shutting down or performing a system update.

Green Steady

Installation was completed successfully, appliance is halted for reboot or installation was not yet initialized far enough for LED control.

Appliance is up and running.
Red Blinking Error during installation.

An error has appeared preventing the appliance from entering the up state.
If no orange light available: appliance is in ART mode.

Red Steady - Appliance is halted and may be disconnected.
Orange Blinking - -
Orange Steady - Appliance is in  ART mode.
Acoustic Signal Frequency Meaning Installation
Beep 1 time

Unit starts booting

Beep 3 times Installation is completed successfully and appliance is halted for reboot. After reboot, one beep indicates booting.

Not all appliances support orange and/or red LED colors. Depending on the appliance type, the status LED might be on by default and it might take some time during boot and installation to start either blinking or changing the color. Furthermore, the status LED might blink at different frequencies.

Serial Console Port

In order to establish a console connection to the appliance using a serial cable (RJ45), you need to configure the serial port on the terminal using the following parameters:

Parameter Value
Baud 19200
Bits 8
Stop bit 1
Parity None
Handshake None

LC Display


This security appliance features a key pad with four keys and an LCD panel on the left side of the front panel. These may be used to obtain certain information and to perform certain commands directly on the appliance.

Keyboard Button Command
Left or Escape

Navigates back or acts like an Escape key while working in the LCD menu.


Navigates up or increases a value.


Navigates down or decreases a value.

Right or Enter

Navigates forth or acts like an Enter key for confirming a configuration step.

LCD Display Menu

You may use the LCD display and the keypad to access certain appliance features. Use the up and down keys to navigate through the items of the main menu.

The LCD menu features the following items from top to bottom:

LCD Menu Meaning
Appliance type, OS version and release number This is the default display.
IP address and subnet mask Shows the configured IP address and subnet mask of the appliance.
Time and date Shows time and date currently configured on the appliance.
Uptime of Barracuda OS The uptime in days, hours and minutes.
Serial number of the appliance Unique identifier for the appliance.
Shutdown menu Enables you to shut down the appliance.
Reboot menu Enables you to reboot the appliance.
Menu to change the management IP address Configure the IP address for the management port.
Menu to boot into ART during the next reboot

Enables you to set a flag that will cause the appliance to boot into ART the next time it is rebooted.
Once set, this flag can not be deleted through the menu. When rebooted, the appliance will not start Barracuda OS, but ART instead. You may connect to the appliance by using the serial console or by SSH. A Control Center managed box running in ART mode cannot be managed through the CC, although it will build a connection to the CC signaling its presence.
