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 Networks appliance it was delivered with.

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 and red and by changing between blinking and steady glowing. The tables below show the different meanings of the different glowing states and acoustic signals:

Not all appliances support yellow 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 (Revision A: DB9, Revision B: RJ45), you need to configure the serial port on the terminal using the following parameters:
