Hi,   This warning message is usually a cosmetic warning when momentary communication with the left front panel is lost. Mostly iDRAC updates fixed an issue wherein the Left Front Panel (LED, Quick Sync) intermittently stops communicating and logging errors SWC5008 and SWC5007. Please make sure the iDRAC and BIOS are up to date. For the latest iDRAC and BIOS version R640 [URL] If you had an IDRAC connection, you would probably see a log like "SWC5008: Unable to access Front LED Panel because of a hardware condition"   If you want to configure iDRAC, you can follow this article; [URL] FW via iDRAC [URL] you can update from within the LifeCycle Controller (LCC). [URL]   However, if the problem persists, a check as follows may be required.Check the Front LED Control Board cable for damage.Reseat the Front LED Control Board cable for connection issues.Replace the Front LED Control Board for LED failure.If this doesn't resolve, you can try replacing it with a known good if you have another R640.   Let us know if this helps!
Good evening folks. I have several racks of R640 1U servers. One of them is flashingscrolling an error on the front panel "SWC5008: Critical" but I'm having a hard time getting any other information on what the problem is. I found a page that says it is "unable to access arg1 because ... " but there is no argument given. Just SWC5008: Critical.  The system is running Debian Linux (Version 10 -- Buster) and I can't seem to find any errors on the operating system level. I'm almost certain that no iDRAC setup was done when these servers were installed. Thanks for any information! Mike
