C240 M3 Stuck at "Configuring and testing memory .."

Question

Hi,
This server's just been returned to us from Cisco, who had it on loan since it was new.   We're trying to put it back into service, but have hit the following problem.
On first power-up the server gets as far as the "Configuring and testing memory .." message.  Just that message, it doesn't show any progress in actually testing memory.   After a few seconds it shuts itself down, then spins up again, repeating that a couple of times before sitting with the "Configuring and testing memory .." message at the top of the screen, but now also showing CIMC IP address at the bottom.   All four LEDs above the power button show steady green,  and the unit ID buttons switch the blue LED on/off as they should.
I can get to the CIMC login screen, but the password's been changed from default so can't get any further in that direction until we find out the new user/password details.  Unless someone knows how to reset CIMC to default.
I've tried the following recovery steps ..
(1) If we set the "Clear CMOS" jumper J2065, the server won't power up.  It powers up to standby, but does not respond on pressing the power button.
(2) Using the "BIOS recovery" jumper J2068 doesn't appear to have any effect, the server does not read the recovery file from USB flash drive.
Any ideas?   
Thanks, 
Tony S

Cheers.  There's not much to reseat at this stage.   The server came back with two CPUs of unknown type, I've removed and set those aside in case they're some sort of weird CPU that needs a special memory configuration.
We've fitted a single E5-2609 as CPU1 and single DIMM in A1.  There are no PCI cards or anything else to reseat.    As a matter of fact the server behaves exactly the same if there's no memory at all, making me think it's hanging up before starting the memory check.
I would love to get into the CIMC, but does anyone know a way to reset the username/password other than via the BIOS screens (which aren't accessible).
Thanks, Tony S
