Where the heck is DIMM 7

Testing, diagnosis, troubleshooting, service, repair – These are common buzz words that we hear quite frequently when people talk about Total Cost of Ownership (TCO) and how platform RASUM (Reliability, Availability, Serviceability, Usability and Manageability) features could help to reduce those costs.

Reducing Mean Time To Repair (MTTR) is one of the aspects that apply both at the factory level and in field service. Advantech’s blade diagnostics are the foundation for a special feature that makes servicing our blades so much easier. All diagnostic software can detect broken CPUs, DIMMs and other replaceable items such as SSDs and disks. But does a message like “Please replace DIMM no. 7” printed on a console window really help service personnel in the field? Well, if they know where DIMM no. 7 is or if they have a map of the blade at hand, I guess that would be fine.

There is a much smarter way to locate a faulty item on Advantech blades (of course). The Advantech diagnostic software can identify the faulty item and then store the specific location in a special register of the hardware. The value of that register can be displayed for a period of time even after the blade has been removed from the system, i.e. the power source. The display items are LEDs located just next to the faulty item, i.e. DIMM7 in our example.

All that a service or factory tech then needs to do after running the diagnostics is remove the blade from the chassis, put it in front of them, press a small push button, known as the “Where-the-heck- is-DIMM-7-?” button, and the LED illuminates and will guide them to the component that needs replacement. No more learning how DIMMs are numbered on that blade and no more looking for the latest maps. Just replace the DIMM next to the LED. That’s it. Simple, or what?
