NSA3600 test light on secondary firewall flashes strangely

I have a pair of NSA3600 in HA and the secondary firewall test light is now flashing two fast and pausing between. in the past (before I updated the firmware to the most recent) the secondary firewall would flash on/off every second in a rythmic state. now I see it flashes twice fast (every half second) then pause for a second and repeat.

this is different behaviour then what I was experiencing in the past. is this new with the recent firmware update?

everything appears to be operating normally so I am not worried, however just noticed this different behaviour and was curious if I need to be concerned.

    Hi @MC2012,

    Thank you for visiting SonicWall Community.

    I presume you are seeing the light status behavior after upgrading the firewall to latest official release firmware version. What is the color of the test light? If you see a double flash, it indicates the Heartbeat exchange between the HA units. This is going to be repetitive on/off cycle.

    I'm gonna refer a KB for your reference on the SonicWall light status. This is just for your reference in case.

    Hope this helps.
