6600 Fan Malfunction on Boot

A couple of days ago my 6600 at my remote QTH started getting occasional audio drop outs. 

I am using SmartSDR version 3.1.8.  I also use a Maestro. 

Thinking it was a network issue, I rebooted the Routers on both ends of the circuit as well as the Cable Modem at the remote QTH and the DSL Modem at the home QTH.  The speeds of the internet at the remote and home QTH were normal as was the latency.  The problem persisted, so I remotely reset the Flex 6600.

After the remote reset, the rig never came back on line.  I remotely turned off the power to the rig, waited 15 minutes and tried a reboot.  I still did not come up.

I traveled to the remote QTH and found the power light flashing green.  I shut it down using the power button, waited a minute and tried a normal restart. After 5 minutes it still was flashing green.

I then powered down using the power button, waited a minute then unplugged the power from the Power Poles on the back of the rig.  I waited 15 minutes, reconnected power and tried to boot.  I still only flashes green.  

I then shut down the rig, unplugged power, reconnected power and pressed and held the power button until I got a steady white. The power button stays white when released.

After that reset procedure a boot sequence attempt gives a flashing green light for 2 minutes and 30 seconds, then gives a red fault error code.  The code is a single red flash that repeats every 2 to 3 seconds.  The manual indicates this is a Fan Malfunction.

The rig is connected directly to the router.  The router does not see the rig during this issue.  I brought the rig to the home QTH and get the same results.  The home QTH router also does not see the rig. 

Have I missed any means of getting the Flex back online?
