Octoclock CDA-2990 produces no signals.

Upon power up, the Octoclock should show all green LEDs on to the left.  After several seconds, the “External”  LED should turn off, and the PPS should begin to blink once per second.  Instead ,this Octoclock simply goes frozen in a state in which the “Internal” “External” and “Status” LEDs remain stuck on.  Nothing occurs after an hour of waiting.  The stuck LEDs are shown in the attached image.

An oscilloscope was used to test the unit, and no signals are produced by any output. No PPS signals are generated, no 10MHz are seen from any of the front panel SMAs.

How should I proceed with troubleshooting this Octoclock?

Attempts to get technical support with Ettus have failed.  A barcode reader says the serial number is 3281D94. I also entered 3201D94 and 3261D94.  All were rejected with the message 

We're sorry, we don't have a match for the number you entered, or a service contract is not associated with that serial number or system.

Other parts of the website indicate that a valid service agreement is required to access technical support.  These errors are shown in the attached images.  Attempts to email the company returns an auto-generated reply that directs you to the support website shown.    This robo email contains the content,

Effective 1 January 2024, the NI/Ettus technical support team has changed the way that we provide technical support for NI/Ettus USRP hardware and software. We have transitioned to the NI Service Request Manager (SRM) to provide direct technical support.  The NI SRM system is now the primary way to obtain technical support for NI/Ettus USRP hardware and software. The NI SRM system can be used to submit new requests for technical support as well as request repairs (RMA).
