Team, any idea why 2 of my R730 servers won't boot after a prolong spell in a cold ISO container - shipped from Auz 3 months ago.  They were fine in sunny Auz in Nov 18  but now back in UK they don't respond.  

The PSU looks good (I've also tried the spare); the iDRAC interface GUI looks good - no alerts or errors. When I push the power on button nothing a happens. There is a BITE message on the front LCD that states " VT2040 System Board voltage out of range"

I've removed the servers from the ISO container and brought them into a warm lab.  

Any ideas?
