Page 25 of your manual details the front panel connectors. The socket is located on the bottom right corner of your motherboard. Not all of the pins will have connections (speaker, chassis intrusion).

The LED SW is the hard drive activity LED. It is a dual +/- connector. For your motherboard, it goes in the lower left hand corner of the board pinout.

This is different than the POWER LED with separate positive and negative connectors that goes in the lower right corner.

I don't believe that to be correct, the LED SW is for the front panel led switch (which seems to be used in conjunction with the RGB Fans).

The manual also seems to be incorrect, listing an HD LED connector when actually there isn't any

I would have connected it to the Power LED connection, LED SW, to my mind is thw LED for the power switch to indicate that it's on and that is usually the POWER LED, Mind you, c-attack is usually right.

Yes, one too many LED and HD acronyms. I had to go get the 740 out of storage and they did replace the HD LED activity light with the HD120 LED fan switch on that case. Since neither one of us has the HD120 RGB fans, that connector serves no purpose. Apparently you can also leave it connected the HD LED activity light without harm, as I have unknowingly done for the last 5 months. Funny little thing in swapping from 540 to 740 and back. Sorry for the bum steer.

Hi again guys.
Now i confused again... This connector is to connect in POWER LED or HD LED?
The POWER LED in motherboard have 3 pinout and LED SW connector have only 2 pinout...
Where is correct connect this LED SW, in POWER LED or HD LED?
The Corsair manual don't explain very well.

You don't connect it all, unless you have HD120 RGB fans and the connection should be on the control box, not the motherboard. I am not sure why they used that type of connector.

Here is another professional who ran into the same issue.
http://www.legitreviews.com/corsair-...eview_185791/4

"When setting up the front panel headers, we encountered an unusual header connection. There were the standard, Power LED, Power Switch, and Reset Switch. Missing is the HDD activity LED, but we found the LED SW header in it’s place. Checking the user manual, it says there should be a HDD LED but there is no sign of it. Knowing there is a LED button on the front panel, it makes me wonder what this could be for. We talking with Corsair, and they stated this is used to control the lighting on their new HD/SP fans, we hope to get some in so we can see how this works."

I haven't done it either, but the only thing that makes sense is a simple on/off switch for the illumination.

Yes, you can ignore it and leave in the other half of the case.
