The hardware configuration list in Table 1 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 Networks NG Firewall or NG Control Center 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 of the different glowing states.

ColorGlowing StateMeaning installationMeaning Normal Operation or Active Recovery Technology Operation

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:

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

Appliance type, OS version and release numberThis is the default display.
IP address and subnet maskShows the configured IP address and subnet mask of the appliance.
Time and dateShows time and date currently configured on the appliance.
Uptime of Barracuda OSThe uptime in days, hours and minutes.

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.
