dittohead Posted March 12, 2018 Share Posted March 12, 2018 So after upgrading to 9211 front hdd led want's working:) 9211 have header for LEDs connection, but HDD LED on front connect via big header to motherboard. Maybe someone research this header pinout? Out of big desire to remove front panel and with probe find LED lines:) Link to comment Share on other sites More sharing options...

schoondoggy Posted March 14, 2018 Share Posted March 14, 2018 I would connect a led to the 9211 led connector to confirm that the drives and the controller are passing drive activity. Link to comment Share on other sites More sharing options...
dittohead Posted March 14, 2018 Author Share Posted March 14, 2018 I measured resistance between LSI's LED cathode and microserver's ground, ~200 Omh, but I not found resistor on LSI, so I think need separate 2th pin, and move it both with pin 6 to LSI header. Or include another one led: into front panel) Link to comment Share on other sites More sharing options...
dittohead Posted March 18, 2018 Author Share Posted March 18, 2018 So front pannel LED works with LSI Turn off server Remove 6th pin from io front connector Take a resistor 220 Ohm Connect second LSI pin on LED header with removed HDD Pin by wire And all works!:) Link to comment Share on other sites More sharing options...
dittohead Posted March 19, 2018 Author Share Posted March 19, 2018 (edited) Small demo and I make a mistake, say "twenty omh" , but this not correct, 200 ohm correct Edited March 19, 2018 by dittohead Link to comment Share on other sites More sharing options...
