6600 (non M) wont boot

  • Updated 5 months ago
Went to fire up the 6600 this morning and  ended up with a triple red flash showing it wont boot. Tried holding in the power button until I got the white but that did not help.

Filled out a help ticket but I think I have heard they are running behind?  Anything else to try while waiting on them?

I am assuming its going back for repair.

Did not know there was a 2.4.9.

I have downgraded, upgraded and did a hardware reset. So would not expect any cache on radio side.

Thanks for the 2.4.9 info. On my way!

Well the 2.4.9 did not help. Still triple reds on DHCP.

But I like the new multi-color S meter!

Just as a follow up I have swapped out the router/modem with an identical model and thought it was fixed but after a half dozen boots it was back to not booting on DHCP randomly.

To summarize, I installed another network switch and new router and had nothing else hooked up to switch and the wireless disabled. So basically the network consisted of the shack PC, Flex 6600, Router/Modem and a basic network switch all hard wired.  I still had the same no boot issues on the 6600.

I did enable the DHCP server on a Cisco router I have as a test and the Flex booted without issues a dozen times using DHCP device.

Tim did tell me that they do have some issues with DHCP on routers provided by AT&T. I am not using AT&T but not ruling out a similar issue.

My router is about 4 months old and has worked perfectly until last weekend.

I am using/tested 12 DHCP devices since that time and with the exception of the Flex they all get an IP address without issue.

I have no issue running a static IP and actually prefer it.  But just would like to know if the radio is OK.

Regardless, I think Flex needs to review their design as not getting an IP address on the network should not result in a no boot warning on the radio where they ask you to send the radio back for repair.

So the radio works using DHCP if you use the Cisco router as DHCP server ?

Do you have the ability to do packet capture on your network ?

Yes boots fine on the Cisco Router DHCP. And yes I have the ability of capture packets and have sent Tim a wire shark file with the 6600 trying to get an IP address.

Why should it not boot without a lan connection?

It should and does boot without a LAN connection. It will not boot with this particular Motorola router connected.

As long as I set it to static IP.  But it wont boot using DHCP on my setup.

Gee Rich, I wont be able to sleep until this puzzle is solved !  I'm a network engineer and love troubleshooting these kind of issues.  I do allot of troubleshooting at work. 

Did the packet caputure show the radio making a DHCP discovery request to Motorola router ?  Did you see Motorola router respond with DHCP offer ?

I have not looked at it in detail yet but the Flex did make the request.  Things from there did not seem to be typical.  I have been planning on doing it again to get a cleaner capture but have not had time.  The last one I ran was pretty "busy" after shutting down a few ports.  I will be happy to send you the current wire shark file if you want to view it.

The thing that is most bizarre is the radios response. In my mind it should either get an IP address from the DHCP server scope or the fallback 169 address. The three red blink light is not acceptable.

Sure, please send me the packet capture.  I'll take a look.  Use email address on my QRZ page.  List the IP's of your radio and router.  Thanks.

I wanted to follow-up on a comment that I had made near the beginning of this thread.  I just received my radio back today from Flex and it now seems to be working fine.  The diagnosis was "Corrupted S/D Card", though there was no indication of what could have caused the corruption.

I am satisfied with the way they dealt with the problem.  I think they really did want to "make it right".  It was 3 days to transport back there, 2 days in their shop, and 3 days to get it back here, all at no cost to me.  I think that this is a reasonable timeline for dealing with the problem.  So, thanks to the Flex Service department, though, hopefully, I won't need to deal with them again any time soon.

I don't know,,but I suspect the SD card failed. Long time ago somone ask what type of  SD card is used. Steve said it is not a card we buy in a store, it is a commercial made card to servive a lot of re writes. I think maybe they got some cards not to standards.

Yeah, I've had an excellent experience with Flex customer service in response to my boot failure issue as well.  I had some "issues" with my Maestro too and Flex couldn't have been more helpful with them (both boiled down to things on my side of the fence). 

As for the failure, I wonder if mine was an S/D card as well.  Since the thing is essentially a giant purpose-built computer system nearly any hardware failure could result in a boot problem.  If there is a new h/w issue causing the few of these that have happened, a bum S/D card is a less ominous root cause than other possibilities.

Could a corrupted S/D card be causing Rich's problem?  I don't know where in the design the S/D card is in Flex radios...  Is it user replaceable?

Russ,  I really don't think so. Mine boots fine with a static IP address but does not seem to like my brand of Motorola modem/router which I have tried two. It is hit or miss and I could not get it to fail last night running DHCP. 

I also am suspect of the thermostat in my house trying to respond to DHCP request but not sure. 

Regardless as I said above Flex needs to relook there DHCP process because I dont feel the radio should not boot because of DHCP.

Rich has been able to make his radio boot, if it were an SD card coruption the radio would never boot.
The card is servicable in the feild. Flex has sent a few out to customers already with instructions.

Damn, it would have been a nice relatively easy fix.  I wonder what could be "special" about your Motorola that isn't showing up all over the place (if it's true that it isn't - I think it is??).  You might think others are using it too?  Anyway, I hope you get it resolved soon somehow.  There's nothing more frustrating that slogging through this kind of stuff instead of USING the hardware!

Thanks for the info that the card is field serviceable Bill.  At least for those with that form of the problem there's hope the round trip time can be avoided!

Rich- I'll ask again since I never saw a response when I suggested adding the Static IP, what model Motorola router is this, I have seen several of the MG series with high packet failures and other issues.Could you please share which models(s) you have been using.

Yes, its a MG7315.

The replacement I put inline to test was the same model. I have not had any obvious issues with it but have only been running it for about 3 or 4 months. I will say performance was better than anything else I have had at the house.

Rich, can I make a suggestion, replace the router, that is one that has had many reports of having bad packet losses, and all kinds of connectivity issues with a lot of devices, tablets, phones etc-Now I guess they can add Flex to the list as well.  I also seem to think that was one with the bad BufferBloat - which if yo plan to run your flex remotely will cause you issues as well.

Thanks for the suggestion but I plan on running it until I have trouble. Just going to run the Flex Static for now. As I said the performance is good and the 12 DHCP devices on the Network have zero issues with it.

I don't run remote so that will not effect me.

My biggest concern at this point is Flex's inability to know there is a DHCP problem and not an actual boot problem.
