New 450i System Reset Exception -- Special Reset Code

Products PMP

Hello,

I have a 900MHz 450i AP running v16.0.0.1.  This has been deployed for 2 months and only have 5 SM's on it so far.

I am seeing the AP reboot by itself one or times per day with the following message in the Event Log:

******SYSTEM STARTUP******
System Reset Exception -- Special Reset Code 00000002 100F11EE 6FF07FF5 0 0 0 0 0 0 0
Software Version : CANOPY 16.0.1.1 AP
Board Type : P13
Device Setting : 900MHz MIMO OFDM - Access Point - 0a-00-3e-45-a0-46 - 906.00 MHz - 5.0 MHz - 1/16 - CC 85 - 5.0 ms - North America/United States
FPGA Version : 020519;

10/15/2019 : 10:13:14 CST : :Board Temperature: 10 C / 50 F
10/15/2019 : 10:13:17 CST : Acquired sync pulse from Timing Port/UGPS

Any ideas what this error means?  None of our other 900MHz 450i AP's running v16.0.0.1 or v15.2.1 are experiencing this.  I upgraded this AP to v16.0.1.1 because of this message and no luck.  Any suggestions?

Please try to upgrade to 16.1, this is the newest, best release for PMP450i 900MHz.

Thanks Eric,

That didn't do the trick.  Still seeing this weird reboot.  I was hoping the debug "code" ment something to the engineers and they would have replied by now.  Rolling this back to 15.2.1 to see if it still happens.

Reverted to v15.2.1 and still happening.  AP rebooted itself 5 times since my last post.  

Every time it comes back up, there is the same message:

System Reset Exception -- Special Reset Code 00000002 100F11EE 6FF07FF5 0 0 0 0 0 0 0

Anyone at Cambium have any ideas on this?  Surely someone there knows what it means, and if it's fixable in software or if this is just a faulty piece of hardware.  None of our other 15+ 900MHz 450i AP's are doing this.

To me, going through the Cambium support channel is worse than going to the dentist.

Brian - We've dug into the messaging and it looks like this might be a hardware fault... I am afraid you'll need to open a ticket with support and get the unit RMA'd. We would like to see this unit.  We will escalate the ticket and ensure this is a better experience than the dentist chair!
