Hi there, We've made some progress trying to find the firmware for you! If you can download the following file: <ADMIN NOTE: Broken link has been removed from this post by Dell>  If you either burn this to a CD/DVD or put this into a USB flash drive, we can use the Unified Server Configurator to update the firmware again. Essentially, follow the steps from my 2nd post but when you are prompted to Select Update Repository, please select Local Drive and ensure that the CD/DVD or USB flash drive is inserted into the server. Let me know how you get on!
We have 7 servers R710 in our datacenter. From two of them we receive sometimes not regulary alert emails about power supply failure. But it takes only a second and is OK again immediately. Sometimes it is power supply 1, sometimes power supply 2. We tried to change cables already but no difference. I tried to update idrac firmware to newest version - no difference. These two servers are the oldest which we have.  Could it be problem with some sensor or what is the problem? I greatly appreciate any help.  Thanks.
