sure for that, I've bought mine on january this year ... problably that's why they didn't argue.sure. but the warranty rules may different, china only parts do not have 3 years warranty.

Well, I do have access to a preheater big enough, and a hot-air gun, but I also have previous experience of tombstoning parts near the one I was replacing, so am only half tempted to give it a go. Then again, it's scrap unless I try...
Update: The pre-heater took its sweet time to get here, but it's a game changer! The lead free solder flows so much easier. Unfortunately I had botched things pretty badly running with just hot air, so was getting no voltage from U4/U5/U6 regulators. Remove/replace them all: Now U4 is 2.5V, U5 is .61V and U6 is zero volts. Let's assume for now that U4 and U5 are functioning correctly... 2/3 is an improvement!Well, I do have access to a preheater big enough, and a hot-air gun, but I also have previous experience of tombstoning parts near the one I was replacing, so am only half tempted to give it a go.

pretty possible its not connected. microprocessors have internal voltage supervisor/reset units.Upon inspection I have clearly lifted the "power good" pad, but it doesn't appear connected to anything?
0.61 Volt ? the regulation range of the TPS62088 is 0.6 - 4 V.Remove/replace them all: Now U4 is 2.5V, U5 is .61V and U6 is zero volts. Let's assume for now that U4 and U5 are functioning correctly... 2/3 is an improvement!
plugged ? I thought they didn't do that anymore today, galvanic process instead.and commercial computer MBs are way too cheap for plugged vias.
As far I know the via would still have to be filled to be plated over. I don't think mass-produced MBs can afford such an expensive process, especially with so much space around.plugged ? I thought they didn't do that anymore today, galvanic process instead.
the galvanic process builds the via by coating copper in the hole.As far I know the via would still have to be filled to be plated over.
Still, too expensive for an off-the-shelf productthe galvanic process builds the via by coating copper in the hole.
all are manufactured that way. it is lower cost because the only way to proper create 0.3mm via'sStill, too expensive for an off-the-shelf product
ipmitool
Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directory
@RolloZ170 did say that the symptoms are different depending on which of the three chips is affected and for how long. If your motherboard is booting - awesome, but you should check the chips carefully and maybe get the board repaired while Supermicro is still handling returnsWell well.. Shuffled PCIE cards around on H12SSL-i (Rev1.01 from china), afterwards no BMC/IPMI. BMC NIC led stays green but doesn't do anything. Heartbeat led blinks fast for ~10 secs and then goes off while power is off. With power on, heartbeat stays constant green. Otherwise the system works and I can boot to OS fine.

fast flashing is BMC bootloader, FW flash is not powered, one of U4/U5/U6 damaged.Well well.. Shuffled PCIE cards around on H12SSL-i (Rev1.01 from china), afterwards no BMC/IPMI.

Yeah. The server was removed from the rack and unplugged. Hindsight 20/20 I propably did touch the MB a bit while shuffling cards/cables. No dropping / big force, nothing I would normally worry about while building stuff on 4 decades. Last time I broke something like this I was 10 years old. Have to be extra careful in the future. Ordered H12SSL-NT for replacement, will try to RMA this after it arrives.fast flashing is BMC bootloader, FW flash is not powered, one of U4/U5/U6 damaged.
have you completely unpowered before swapping the PCIe cards ?
Hi, I have exactly the same problem as in this discussion thread.these are your FW chips
