Fan Errors - How are they Displayed / Reported

A few questions about the error feedback / display when there are fan failures in the 6300, 6500 and 6700 radios.

On the 6500 and 6700 when the CPU or FPGA fans fail, the errors are shown on the radio display.  





QUESTIONS

1 - How are the CPU / FPGA fan errors communicated on the 6300 since it doesn't have a display on the radio?

2 - Are users alerted to the errors when they are operating remote?  If so how?  

3 - What error messages are displayed when the larger 80MM case fans fail?   How are these errors displayed?


Although I searched the forum I couldn't find these answers but apologize if they are covered somewhere.

Excellent questions AL,   It would be good to know, if there were to be some sort of failure that reported on the 6700 display at the Remote, how I might be notified via on the Maestro I use here at the HOA.

I think the current "answer" , however, is that there is no way for the user to know remotely exactly what the radio server was reporting as a problem.

Larry,
Thanks for you feedback, so on Question 2, unless we hear differently I'll assume that remote users are not informed of errors that occur on the server or messages displayed on the radio display.  

It sounds like there is an opportunity to add some error logging on the radio that would write the messages to a time stamped circular file.  For example when the FPGA fan error is detected and before shutting down, write an entry to the file.  Then provide a menu option for a client (SSDR, Maestro, etc) to display the errors after the radio is rebooted.   It would probably be useful even for local operators to be able to see an historical list of errors, something like the "event log" in Windows. 

Maybe someone  would like to add that as an idea for consideration if they think it is worthwhile.    As more people operate remotely the benefit of this feature could increase.  It seems like this could be a good troubleshooting tool for FRS support as well.

The Windows event log would be on the Client Side: but if the Server Side has an error, Network or Safety for example, it will not be communicated in real time to the Client.

More workable is a Server Side portion of persistent memory and API commands that will query that "log".  There is no time base on the Radio Server; or is there something in hardware?

Stan,
I probably didn't explain it well but what you described is what I also meant. The client side menu option would retrieve the events from the radio server through the API.

On Question #1 - How are the CPU / FPGA fan errors communicated on the 6300 since it doesn't have a display on the radio?

I heard from a 6300 user that had the FAN problem.  He said the radio just shut down and there was NO message or indication of the cause of the problem.  He learned of the problem after sending it in to have the radio repaired.  

Unless someone with a 6300 has other feedback, it seems that having spare fans is not worthwhile for the 6300 owners since they won't know why the radio failed.  This looks like another "use case" for the error logging feature.

From above on the 6300:  ...the radio just shut down and there was NO message or indication of the cause of the problem

Like the 6300, the new 6400 and 6600 also don't have displays on the front of the radio.  I wonder how errors like the fan error or low voltage errors will be communicated to the users on the new models.  

It's sounds like the radio "error logging" feature and error log display option on the client would have application to those new models as well.   It could be a feature that benefits remote and local users as well as users with the models that don't have a front display. 

Maybe FRS has something  planned to display these messages on the new models???

I've updated my web page with the latest user feedback on the 80MM fan failure.  

http://www.nn4zz.com/FLEX6700.htm#FANs_

It appears there may be an error message displayed on the SSDR client related to the 80MM case fans.   The error message may be temperature related rather than fan specific, see snapshot below.  There may be an error displayed on the radio display also but this has not been confirmed either.  From some earlier posts:




Most of the 80MM failures seem to be detected when the bearings either click or whine or run very loudly.  It appears that error messages specifically related to the 80MM fans are rare.

If anyone has more data, corrections, or the specific error message for the 80MM fan failure, please let me know and I'll make the necessary changes.
