    HP Proliant ML110 G5 - CAUTION RISK OF FIRE (epic fail!)

    Hello everyone.

    I am not sure that this is the correct sub-forum to post but i think its the closest to the problem i met.

    One of our HP Proliant ML110 G5 servers was switched off and the computer room had the smell of burnt plastic...
    If the server was powered on it continued to run and smoke came out almost immediately and the PSU did not switch off, at least until we powered down the server by hand.

    The problem rests on a Y splitter molex to 2X Sata power adapter.
    Our cable has a manufacture date 25/1/2008.
    HP released a product recall just in Dec 2013. Of course we not informed about the problem.

    Looking around the internet we seem to be "lucky", as many others had the entire computers destroyed by the fire.

    It is worrying that the PSU's short protection does not kick in, but measuring the resistance of the shorted burnt plug (+12v to GND) shows about 50ohms which i think the PSU will not detect as shorted.

    I posted here as it might help someone else to check if they are using the same adapters.

        Hii,
        Hp ML110 G5 servers catch on fire ,I have a set of 11 Hp ML110 G5 servers all purchased at the same time. So far 7 of them have had a power cable connected to the hard drive melt down and catch on fire, some in the middle of the night when no one was around. Fortunately the fires were small and contained within the case, but it seems very odd that so many of the servers are experiencing the same (very dangerous) problem.
        Of course, they were just out of warranty when the problem started. Now, when I try to go through the web site to initiate a chat or email with HP, it asks for the serial number and tells me that I cannot contact Support for free since the warranty is expired.

        How do I make the right folks at HP aware of the problem? If my office space burns down because of an issue with a whole batch of their servers, I am sure my company will seek some kind of recompense, in warranty or not...

          Isn't that always the case?

          Seems like it's always those adaptors and always the same type of adaptor that burns...
          I've seen it already many many times on the interwebs, some here probably in real life. It's pretty nasty, but maybe the connector spec is just wrong...

          Why haven't they gone with a connector printed on the PCB? similar to the PCIe connector...

          1. For a short to be detected, there has to be an actual short and not just a shitty connector...

          2. 50Ohm on +12V equals to about 0.24Amps...
          But there also is a motor and so on...

          And you do not need high amps to burn something, just a very very bad connection...

            SATA power connectors are bullshit - the contacts are too small for a power hungry 3.5inch drive.

            stick to using the 4pin molex, and dont buy any drives that dont have one.

              After looking a bit more at the pictures, I wonder if those disks are salvagable.

              You 'just' need a S-ATA (or maybe better a Molex) extension, sidecutter, good soldering iron and there she goes...

                  interesting, optical drives have very low current needs - unless something shorted out.

                    optical drives can pull 1-3 Amps of power on the 12V rail when a disc is being spun up. But once disc is spun, they use no more power than a regular 3.5" HDD, and even less when there is nothing.

                    Thus, the conclusion is:

                    I saw one pretty burned up at work about 3 weeks ago - a cheap Molex to SATA adapter in a eMachines PC that was installed by the user.

                    The only other connectors I've seen short and burn up are floppy connectors.

                      i'd say rohs strikes again, causing tarnished connectors. this increases the connector contact resistance until things get too hot and start a fire. the high humidity and temperatures in singapore are just the arch-nemesis of rohs.

                        Had this happen to me on my downstairs PC. Assuming it was the Molex that shorted. I have stopped using these whenever I can.

                          shit connections for sure . arcing causes lots of heat then the plastic melts and makes things worse . i come across this sort of thing most days

                            Had a SATA connector cable burn up on me once due to bad connection. It was in a Raidsonic 3.5 inch HDD case. Fortunately, the SATA cable was the only victim.

                              The Molex connector on that adapter looks fine. I only see the SATA connector is burned.

                              That said, this makes me want to install a Molex connector on all of my SATA HDDs. Either that, or a 5 Amp fuse on every wire strand that has SATA and Molex connectors - but both of these are a bit more work that I care to do right now.

                              Funny thing is, if you do an image search for "burned Molex connector", most pictures you get back are of burned SATA connectors, lol

                                7th December 2017, I had a server fire in a Proliant ML110.
                                I was working late (luckily) and I had a server ML110 on the bench behind me.
                                It was on the network & switched on. I was using it for a small project, but hadn't actually done anything with it for a couple of months.
                                I could smell burning, and by the time I found where it was coming from, smoke was now emitting from the server.
                                I pulled the plug & took the server outside.
                                I removed the side panel & there were flames at the rear of the drives.
                                The flames extinguished & I left it to cool down
                                it looks as though the cables at the rear of the hard drives had caught light.

                                  This has to be somehow related with high humidity levels or some contaminants in the air (don't laugh, I've seen once a server kept in a kitchen ).

                                  Probably the contacts corrode due to humidity/contaminants and the increased resistance causes them eventually to catch fire.

                                    Yup. "Good ol'" SATA power connectors are know to do that.

                                    This can never happen with Molex power connectors. The only Molex connectors I've seen cause a short-circuit were those super-cheap flimsy ones that come with cheap fans and cheap connector converters/extenders.

                                    Sounds about right to me - at least the corrosion part. As to whether it can happen only in a place with high humidity or not - that I don't know. Either way, I'm sure it must be related to RoHS and/or manufacturers cutting a corner somewhere with the connectors, thus allowing them to oxidize much easier.

                                      Something caused the contact resistance to increase and from there it ran away into self-immolation.

                                      Word to the wise regarding PSUs with edge connector output connectors that slide in and out of server chassis. DO NOT slam them into the chassis. If you don't cause damage severe enough to cause an immediate failure you may damage the mating connector contacts and/or solder joints, setting in motion a slow breakdown of the contact and eventual overheating. It make take a couple of years, but it will be destructive and ugly and it will smell really bad.

                                        Vaya!!! que sorpresa no tan agradable y que problema.
                                        Sobre la fuente de alimentación he de añadir que al tener el máximo de 365W es probable que conectores tipo sata estén expuestos y más si su funcionamiento es de casi 24H. sin interrupción...normalmente se arregla con un molex de cuatro pines con extensión sata.
