I wonder if the debug led is showing anything...

 

[luckylinux]

I only have UDIMMs in ECC right now. I can't access BMC. I get nothing on VGA output and the IPMI doesn't seem to get an IP to connect to.

I ordered a cheap single dimm and a cheap pentium G cpu to test out with.

From my experience with the Intel CC150 which apparently does NOT support ECC unbuffered RAM, it booted up just fine with ECC unbuffered RAM. It just did NOT enable the ECC Feature and you could see that in GNU/Linux via dmesg / dmidecode -t memory.

Different Platform sure, but I was also surprised that mine posted at all with ECC unbuffered RAM, if ECC wasn't supported.

Nothing on the debug. It never even lights up. I feel like its a power issue of some sort.

I ordered a cheap Pentium CPU and some small RAM to do more testing. If it fails, I'll just send the motherboard back.

The motherboard options for this CPU are very limited and many are only available via grey market like ebay.

 

[MSameer]

Got the cpu.

I can see bmc is getting a lease from my dhcpd but i am unable to access it or even ping.

I am connecting the cpu fan to fan1 and it's rotating. BMC heartbeat seems fine.

Not sure what is going on here.

I just had a similar situation with a Supermicro X11SCZ-F, not sure either .

I needed to turn the System ON in order for the BMC to get an IP Address from DHCP for some weird Reason .

Possible Reasons in your Case might also include VLANs or a duplicated IP Address (possible if you use dual redundant Routers which failed to synchronize themselves with each other). Or you got a Network Loop somewhere (I had it with my UNIFI WiFi Access Point).

I'd suggest booting a GNU/Linux LiveUSB (I had better success with Ubuntu on UEFI Systems, although I usually use Debian in BIOS Mode, default Debian GRUB Installation for UEFI seems to be messed up) and make sure that you have dhcpcd enabled (or NetworkManager or e.g. dhclient -v in a Shell Script e.g. /etc/rc.local Auxiliary Service with associated Systemd Service enabled).

Then check with ipmitool lan print what is going on. You can also reset the Password later on.

 

[MSameer]

I have a single router but 2 switches connected via 10g copper. A messy setup for a messy home ;-D

Opnsense happily gives a lease. I did a cmos reset and connected the vga port (Yuikes) and guess what? The board entered the bios by itself. Now to find a keyboard to complete this pre-historic troubleshooting. Still cannot access ipmi though

 

[MSameer]

Got it working.

Bios -> server mgmt (management) -> bmc network configuration -> switch "BMC out of band access" from no change to enabled.

The board is an ovh oem board apparently. It is running ovh bios. Reminds me of the mc12-le0 liquidation...

I do not know the default password. Neither admin/admin nor admin/password worked. To reset it:

1. Enter bios
2. Load default bmc settings
3. Reboot
4. Go make some coffee (bmc needs time to initialize).
5. Enter bios and toggle bmc access
6. Profit.

Boy, this bios feels clunky. I miss supermicro.

 

[MSameer]

I forgot. Once bmc network defaults are loaded, login via admin/admin and you will be prompted to change the password

 

[MSameer]

@Magnet any luck?

On Supermicro at least you should be able to reconfigure the IPMI Admin Password fairly easily from a Live Linux System (e.g. LiveUSB or NetBoot):

# Reset ADMIN Password
# Admin is typically User #2
ipmitool user set password 2

You can also reconfigure IPMI to use DHCP (then reboot the BMC) by Issueing these Commands on Supermicro Motherboards:

# Configure IPMI to use DHCP IP Addressing
# Supermicro: use channel 1
ipmitool lan set 1 ipsrc dhcp

# Reboot the BMC
ipmitool bmc reset cold

On the Fujitsu TX1320 M3 I had to use another Channel, so it might be a slightly different Command in your Case too:

# Fujitsu TX1320 M3: use Channel 2
# Configure IPMI to use DHCP IP Addressing
# ipmitool lan set 2 ipsrc dhcp

# Reboot the BMC
ipmitool bmc reset cold

@Magnet any luck?

I have an extra CPU/RAM module on the way to check. Hopefully get some time this weekend.
My current config never got a lease on management.

It doesn't matter because even if you get a lease, you might not be able to access IPMI.

The boards are clearly not new. I can tell because I have 2 boards with different bmc access configuration.

Try connecting a vga cable and see what you get.

My RAM is samsung m391a2k43bb1-ctd

EDIT: It is possible your bmc is configured to not get a lease. Try popping the cmos battery?

 

[Magnet]

Well. I've tried everything I can think of.

I did the clear CMOS procedure and ended up putting in a new battery just in case
Tried my original set of 4 UDIMMs, all 4, 2 and 1 DIMM at a time, tried another single UDIMM
Tried my original 2324G and also a compatible pentium
Tried multiple PSUs
CPU fan is connected to one of the fan headers, it never spins
Nothing else is connected except power to motherboard
Tried with/without keyboard in USB port.
When I power the PSU, i get a flash of lights from the ethernet ports, then a slow blink near the ASpeed chip and a solid green between RAM and 24 pin power.

Nothing happens if I short power on pins.

I never get anything from the VGA port.

I think its busted unless anyone has any ideas.

 

[MSameer]

And have you connected both 24 pin ATX and 8 pin eps connectors?

Do you have a ch341a and the ability to dump BIOS? I don't think you will get fan spin if the BIOS is corrupt/missing. I would try to restore the BIOS from a known-good dump of someone else with a working board. I don't know if BIOS is socketed on these boards, but some newer platforms have 1.8V BIOS chips, so measure voltage before you YOLO at 3.3V, or just Google the part number of the BIOS chip and find the datasheet.

 

[Magnet]

And have you connected both 24 pin ATX and 8 pin eps connectors?

Yes both 24 and 8 pin are plugged in. This is from a PSU that works on another board I'm testing.

 

[MSameer]

Well, I'd say it's busted then. Return and request another unit?

If shorting the pins does not work (and you are shorting the correct pins) then nothing else can be done :-(

 

[Magnet]

I don't have a bios reader/programmer.

The label on it says:

E3C252D4U-2T/OVH
1.21

I wonder if I could source one pre-written with a fresh BIOS?

 

[Magnet]

Yep. confirmed that also. My timeline for return is closing March 7, so might be initiating a return

 

[MSameer]

We all like to tinker but in this case I'd return and order a new board. Why tinker with something when it might not work at the end?

I ordered 2 boards and they both work so it's just bad luck on your side.
