Hi, can someone by change provide good pictures of the optional JSEN1 temperature sensor that is used for multiple supermicro boards?

I've only found this one here and I'm currently trying to figure out if and how adding additional sensors to the board works. It can't be as simple as just hooking I2C sensors up to that bus, can it?

Product number: MCP-280-00033-0N
eBay link: https://www.ebay.de/itm/335379055576

The documentation is kinda sparse on that.

I currently assume that JSEN1, JIPMB1, JSMB, JNVI2C1, and PWRI2C all expose the same I2C bus as the SMBus on the PCIe slots does but with slightly different pinouts each.

After that the question is how to get the sensors to show up in the BMC but one problem after another.

Edit: Huh, so this is what reddit does when I click on the "there is a better community for this post message" when that community doesn't allow reposts. It literally just automatically copies the entire post instead. Interesting...

Edit 2: In the repost over in r/HomeLab someone mentioned that the I2C bus is basically unusable since Supermicro started signing the BMC firmware. Is this true?

When I turn on the power supply, the LEDBMC blinks green, and LED9 blinks green, the latter blinks fairly quickly. Then after perhaps 15 seconds, LED9 stops blinking, and turns off. LEDBMC soon becomes a steady green, for about 20 seconds, then goes back to blinking green. Also, the HD on the case is blinking red.

Not sure what is going on here, anyone know this motherboard?

This is in the US, no peripherals, and being used for research.

Good evening,

New to this section and have some questions regarding the Supermicro branded LSI-9003 cards. My current setup is an X11DPU with two Xeon Gold 6248's, 512gb DDR4 ecc 2133 ram, NVIDIA Tesla P100 16g, 3 sas3 LSI-9003 cards, 12 3.5 bays and two external 4 3.5 bay cages. All firmware BIOS and BMC are most current.

When I use Supermicro branded AOC-S3008L-L8i v2.0 HBA IT cards with the most current 16.00.14.00 firmware the X11 IPMI does not pick up the cards or drives no matter where they are in the PCI slots. If I take a generic LSI-9003 based card and cross flash the Supermicro IT firmware, the cards and drives are found by BMC and IPMI shows the info for each plus they show up in the sensor readings. I like this because it reports the card and average drive temps. I would prefer to use the Supermicro AOC cards as they are slightly smaller and I can fit one with the quad 10g PCI bifurcation card, also the AOC cards have a PC bracket with larger holes for better air flow. I messaged with Supermicro tech support about this. They confirmed that Supermicro SAS3 card firmware on a generic LSI-9003 card would be picked up by the BMC, but refused to acknowledge or explain why the Supermicro AOC-S3008L-L8i cards with the same firmware would not.

Any thoughts, ideas, or explanation would be appreciated.

Hi peeps, I am planning an AI server build and am looking at the ASRock Rack ROMED8-2T and Supermicro H12SSL motherboards to pair with an EPYC cpu.

As we know, the RAM prices are insane and I have found some 6 year old 64GB modules locally for cheap and I would like to know if anyone can confirm if they work in either of these or related motherboards.

This is the link to the RAM:

I have couldn't find it on these two motherboard QVL but my understanding is that some modules are compatible even if they are not listed.

Hey everyone, I’m the developer of Redfish Console, an iOS app for connecting to your server’s BMC over the network using Redfish.

You can view system health, sensors, hardware information, and event logs, plus use power and locator controls where supported.

I haven’t tested it across different physical hardware yet, so I’m looking for volunteers with Supermicro systems to help test compatibility and share feedback.

Looking for Supermicro testers

I’d appreciate feedback on what works, what doesn’t, and anything you’d like to see improved. DM me with your server/motherboard model and BMC firmware version, or share your experience in the comments.

Pricing

The app is free to download. Viewing system information, hardware, logs, and using controls requires Pro:

• $1.99/month or $19.99/year, with a two-week free trial.
• $39.99 for lifetime access.

Privacy and diagnostics

The app connects directly to your BMC.

Optional diagnostics help me diagnose app crashes and errors and improve stability. They don’t track your activity or record your screen.

Reporting is on by default. You can turn it off under Settings → Share App Diagnostics. Reports go to an external diagnostic service and can include crash details, app/device information, and technical identifiers.

Redfish Console on the App Store

I’d appreciate any testing, bug reports, or suggestions!

So I went to download BIOS and BMC updates for my X12STL-IF and it's trying to make me log in. I thought OK, this is technically a server board, so let me try a prosumer/gaming board instead. Same thing.

The "continue as guest" download option is gone. I now have to create an account? And I have to use a "work" email and provide my company name? So they're going to reject say a gmail.com or outlook.com account?

Seriously, what is wrong with Supermicro? Yes, I know there are ways around it, but why do they, yet again, feel the need to make it as difficult as possible to download firmware and utilities from their official source? I just don't get it.

I've been a fanboy for a long time. I have several servers and all of my desktop boards at home are Supermicro's.

Hi, does anyone know if the RSC-R1UG-E16R-X9 will work in my x9SRW-F. Currently I have the RSC-R2UW-E8R plugged into the same slot. if it doesn't work is there one that will allow me to plug a GTX 1050 half height into the same slot for a jellyfin server?

I've decommissioned a SAN recently which was new in 2011. It was a SuperMicro 4U chassis with 16 bays, and a BPN-SAS2-836EL1 backplane. I've got rid of the original motherboard supplied, which was an ASUS, and have been thinking about getting a recon X10 motherboard of some kind, to bring it in line with the rest of my fleet. However, whilst the original unit was hardware RAID, this time around I'd want to run it with ZFS and software RAID, so would need a different HBA, but will this backplane, the BPN-SAS2-836EL1 be able to work in such a setup? The chassis has two 1200W PSUs.

Hi,

seem to break transceiver and twinax compatibility. Anyone else experienced it?

 Possibly worst firmware release ever from Supermicro Networking? 

 Config that worked previously no longer works. I used 1.4.1.1 and regret upgrading. Any hope that I can get my ports and trunks working again besides a downgrade?

Ref.: https://www.supermicro.com/wdl/Firmware/Switch/SSE-3548/

Any help would be great. It’s been a really long time since I built a server. I need some help identifying what these two cables are and where they go on a ATX Sabertooth Z97 Mark 1 MB.
Thanks for any help.

Hey everyone,

I have a workstation that originally had four RTX 3090s in it, and I’m hoping someone here has dealt with a similar power issue, especially with the same Supermicro power distribution board.

The system has an ASUS Pro WS WRX80E-SAGE SE WIFI motherboard, a Threadripper PRO 3995WX, and a Supermicro PDB-PT747-6824 power distribution board with a PWS-2K20A-1R power supply.

A few months ago, the system stopped recognizing all four GPUs and would only see two. I recently moved the workstation to a new location and decided to put it back together with just two 3090s. It powered on, but shortly after I started a stress test, I smelled smoke and the system shut off.

I found that one of the white GPU power connectors had burned pretty badly. The plastic is discolored, some of the wire insulation melted, and there was exposed copper around the connector. I’ve included pictures of the damage, the board, and what a good connector looks like.

I’ve already cut off the damaged connector, and the system has been unplugged since. I haven’t tried powering it back on.

At this point, I don’t really need all four GPUs in this machine anymore. I’d be happy running two, or possibly three, if I can do so safely.

What I’m trying to figure out is whether I can permanently take that damaged power branch out of service, properly terminate and isolate the individual wires, and continue using the remaining GPU power connections. Or, given how badly the connector burned, should I be replacing the entire harness or PDB?

I’ve looked into individual closed-end wire terminations, but before I go that route, I’d really like to hear from anyone who has actually worked on one of these boards or dealt with a similar failure.

A few things I’m wondering about:

• Has anyone seen this happen with a PDB-PT747-6824 or its GPU power cables? Did you figure out what caused it?
• Is there a way to remove or replace just the damaged cable at the board, or is replacing the whole assembly the way to go?
• If I stop using that branch entirely, is there a safe way to terminate the remaining wires, or would you avoid that altogether?
• What would you inspect or test before trusting the remaining connectors with two 3090s under a sustained rendering load?
• Does anyone know where I could find a replacement board or harness, even used?

The workstation is mainly used for Nuke and C4D/Redshift rendering, so I want to make sure whatever I do will hold up under load, not just boot into Windows.

I’m including several pictures to show the damage and how everything is connected. Any advice from someone who has worked with this setup would be appreciated.

This is what I was thinking of getting to terminate the ends of the cut cables (or if someone has a better recomend - https://www.amazon.com/Nilight-Closed-Terminal-Connector-Warranty/dp/B07T1H6N82/ )

Thanks!

I recently started the construction of my new home server project. I've assembled the chell without the CPU,Ram, nor storage or PCIe cards. I've been trying to connect to the m12swa-tf bmc ast2600 but have been unable to do so. I cannot get it to grab an IP nor can I find it on the fallback IP.

According to the motherboard manual it looks like the only connection to the shared NIC is through the CPUs PCIe 0 lanes. I didn't think it was required, but does anyone know? I've spent a good 6 hours stuck so far. So thanks in advance.

Edit: Solution, Installing the CPU and a single stick of Ram, caused the ipmi interface to be reachable on the local network at the appropriate IP.

The specific model of the server is CSE-847E16-R1400LPB.

I believe there may be an extra SATA power cable or at least an extra molex connector that I can use but it's all hidden. My question is, what is the easiest way to access these cables? Does it involve removing the motherboard?

I know I should provide pictures but I can't do that right now. I appreciate any help you can offer me.

Disponemos de un servidor Supermicro X13 con un Xeon 8558u, 128gb RAM (4x32), RAID 1 por VROC en 2 SSD SATA conectado al backplane y una gráfica Nvidia conectada a la tarjeta PCIe.

Tiene instalado Windows Server 2025, pues el rendimiento es muy inferior a un servidor con un Xeon de 2011, con 16GB de RAM y un SSD SATA.

Navegando por el Explorer, la carga de archivos/directorios no es instantánea, se queda unas milésimas en blanco y ya carga o incluso sale el icono de cargando mientras aparece.

Se ha revisado todo, controladores, estado del RAID, Defender, etc. Al final hemos actualizado la BIOS y la BMC y los problemas han aumentado. Ahora no reconoce el sistema ni la BMC la tarjeta gráfica.

He visto poca información al respecto, ya que no hay un changelog en el paquete de actualización de la BIOS/BMC que indique los cambios. El Windows Server 2025 lo hemos virtualizado y corre perfectamente bajo un hipervisor con muchos menos recursos que el hardware físico.

Llevamos ya semanas liados con él y no encontramos el porque de esa lentitud y ahora se añade que no reconoce la gráfica al actualizar la BIOS.

¿Os ha pasado algo parecido?

Is there any reputable sellers in the US that have this chassis?

I opened an RMA with Supermicro for an item I want to return. I shipped the item to Supermicro and they acknowledged receipt of the item three weeks ago. They said in their email that I would receive a refund on my credit card within three business days. I have not received the refund and Supermicro is not responding to the follow-ups I have sent via email.

Has anyone else gone through the return process with Supermicro? Is this typical?

If you are interested, read this. Have a fun.

I was given a PC with a X9DRL-iF motherboard. Whenever I boot it up, it gets stuck on this step where it gives two short beeps and has F2 in the bottom right. Has anyone else ran into this issue before and know how to fix it? It seems a lot of people run into a 2F error, but I haven't found any documentation on a F2 error.

Additionally I did have the thought that it just needed me to press F2 on the keyboard, however I tried that and it didn't work.
