This is primarily directed at the Adtran folks and/or anyone who has had a similar problem where a TA900 loses its boot hint.
Scenario:
Customer has second generation TA924e which has been service for some time running R10.5.2. Unit is supplying PRI and analog lines from SIP trunk, not used for data. Customer called in this morning reporting all phones down, T1 lights red, box unresponsive. They tried power-cycling with no effect.
I programmed a spare unit from RANCID backup and swapped it out. Customer back in service.
Brought old unit back, on the bench it comes up in bootstrap# mode.

And all is now just fine. Power cycle unit, it is happy, boots consistently. But can I trust it, and what caused it to lose its boot configuration? Should I try to RMA the box? It's working fine now so probably not.
What is the exception report file? I haven't tried to download or open it, is this the type of thing that Adtran support would want to see, or can mere mortals decipher it? Is there a hardware issue and can I trust this unit?
