Bought one of these.
- Didn't have RAM previously to test so just powered on to see what happens.
- Booted, had a static IP set (192.168.33.33?) for BMC but screen said No Ram
- Got some RAM, turned it on, stuck on "Please wait for BMC initialize..." with an 06 code
- Unplugged PSU, removed BIOS battery, waited overnight (~8hours)
- Turned it on, and it POSTed. Able to get into IPMI, etc
- It's still on, will see what happens.
