hawihoney Posted August 28, 2015 Share Posted August 28, 2015 I finally did upgrade my old LimeTechnology MD1500/LL server with a Supermicro X10SL7-F mainboard and several other new components. The system is working, nearly 5 times faster than the old build. However, there's one small thing that I don't get to work. The Power-LED on the case does not work. I did connect the Power-LED cable from the case to Pins 15/16 on JF1 (Front Panel Control Header). LE6 (Power Status LED) shows green when Power is on. Do I need to change the JLED1 (Power LED Indicator Header)? If yes, how? The HDD-LED connected to Pins 13/14 on JF1 (Front Panel Control Header) does work. Thanks in advance. Link to comment
HellDiverUK Posted August 28, 2015 Share Posted August 28, 2015 Supermicro's LED pinouts are pretty bizarre. Try swapping the leads round. I had a lot of trouble getting mine working, but got there in the end. Basically, the power switch is at 1&2, and the power LED is at the opposite end before the gap. Link to comment
hawihoney Posted August 29, 2015 Author Share Posted August 29, 2015 Thanks for your answer. Did swap as a test - without success. The correct pins are connected, just before the gap, next to HDD-LED. HDD-LED works perfect. Seems that I need to live with a non-working Power-LED. Thanks. Link to comment
HellDiverUK Posted September 14, 2015 Share Posted September 14, 2015 Is it a blue LED? I do remember having issues with a blue LED not working on a Supermicro board. I just swapped the LED for a green one, and that worked OK. I think some blue LEDs have different voltage, and don't seem to work too well on Supermicro boards. Link to comment
garycase Posted September 14, 2015 Share Posted September 14, 2015 Just for grins, temporarily disconnect your HDD LED and then connect the Power-LED cable from the case to Pins 13/14 on JF1 (the HDD LED connection) just to confirm that the LED is actually working. If it doesn't work with that connection either then it's likely just a dead LED. Link to comment
hawihoney Posted September 27, 2015 Author Share Posted September 27, 2015 Just to tell what I found out: During upgrade of both servers (MD-1500/LL, MD-1510/LL from 2008/2009) to this motherboard I couldn't get the Power-LED to work. No chance. The pins on JF1 (15/16) didn't work. But the MD-1510/LL had a 3-pin Power-LED cable. I could get this to work on JLED1. Now I need to find a way to change the 2-pin Power-LED cable of my MD-1500/LL to a 3-pin Power-LED cable ;-) Thanks for listening. Link to comment
