  • IBM server x336 modification SCSI to SATA – 2 (LED Indicators)

    2012 - 05.17

    This is small update of article about modification server IBM x336 from SCSI to SATA.

    Today I’d like to talk about front LED indicators.

    Our cheap sata backplane has two outputs for LED indicators. One is for power and one for activity.


    I’ve bought two colors led for indication power and activity of each HDD. As I dicovered later activity output not work properly.

    If you never work with two colors led – midle pin is common Ground and side pins are VCC each for one color.

    After all mount led and connect to our backplane. I use glue pistol to hold LED in correct position.
