ProLiant BL460c Gen9 Stops on BIOS

[JM3]

We're having a problem with ProLiant BL460c Gen9's. We bought 4 and all have had the same problem. Two were replaced, 1 was fixed temporarly by the following procedure:

Switch 6 needs to be set to On, put server back into the enclosure and powered on for a few minutes, then powered off and switch 6 set back to Off.

Tried this again but server is not getting past the first BIOS screen. Motherboard is being replaced today but surely there is an underlying fault. Tired to escalate with Ent. Support but nothing has ever happened. Anyone else having this problem?

This advisory is exactly what we are getting but with different HBA's (HP QMH2672 16Gb FC HBA)
