The alarm light on my sonicwall 3360 has been blinking constantly. There's no errors on the log except some spoofing alerts and regular vpn logs. I had rebooted the firewall last night and the alarm light still didn't go away. Any ideas?

RE: digitap's link..

One of the reasons listed is a Fan not working or being too hot.  I'm sure you know that heat can be a killer for electronic equipment.  Even if the device has an overheat shutdown system build in, if the device is allowed to run close to that limit for a period of time, there can still be damage from that heat even though it didn't do an auto-shutdown.  Most are designed to shut down in the event of a cooling failure and not a steadily increasing buildup.  (Frog in boiling water syndrome.)

My rule of thumb is if it is too hot to hold the device case against your cheek for a few seconds, it is too hot to be running well.  If it is too hot, at least get a fan blowing on it until you can find out why.

Just FYI

We had a sonicwall get too hot and sound an audible and visual alert.  Checking the logs indicated this was the issue.  There was also indication the appliance would soon die...which it did with much fan fare.

I'll bet.  
I had a sonicwall just up and die one day (5 yrs old).  Had a new one the next morning on warranty.  

Went through 3 netgears (FVS124G) in 18 months.  None on warranty - always something `wrong'.    
Never again.

Thanks, there is nothing in my log for a failed fan, but there are ip spoof alerts. and the document digitab shared said spoofing is one of the minor alarms.

Thanks
