Hi Stefan,
Thanks for the answers.
The background for the question is that our colleagues designing the main blade intend to have a box for testing out of the shelf and want to use the IPMC standalone mode. (At Stony Brook, when testing out of the shelf, we don’t use the IPMC and instead have a way to bypass with jumpers.)
For the standalone mode test we made at Stony Brook, we connected a bench supply of 48V to the main blade, (which we routinely do), saw the management power come on, and then used the serial console and ipmitool to issue the “go into standalone mode” command:
ipmitool -I serial-terminal -D /dev/ttyUSB2:115200 raw 0x2e 0x0d 0x0a 0x40 0x00 0x02
We expected that the board would then come up as usual, starting with the 12V payload power, but nothing happened. ttyUSB2 happens to be the serial console port on our system.
Do you have any suggestions?
John
