Hi All!

QUICK question--How can you tell what is the positive and what is the negative sides of the HD LED, RESET SW, POWER SW connectors of the case switches that plug into the board?

I'm putting a new motherboard in my old Chieftec Mini Dragon case and I can't find the info on it.

The connectors do have a "triangle" on one of the ends, but I don't know if that means anything.

Thanks,

Look for a small triangle embedded on the wire lead connectors to position the motherboard connector pins CORRECTLY...Look for pin1 to be labeled on the motherboard as a small "1" embedded either to the LEFT or right of the group of pins....Guessing is OK when connecting a wire to a connection......if it doesn't work no harm is done.......You can also get this info from the motherboard documentation.

Pages 204 -206Generally, white is negative, and the little triangle on the connector is positive. on a STANDARD panel, the connectors are in this grouping ::::. where it goes:

'pow led''power sw'
'HDD led''reset sw''extra pin'

In this order

+- +-
+- +- . therefore the triangle should always go to the left.

By the way, the LEDs are also Diodes, so if they are backwards the first time, nothing will short because no current can flow.

The switches are non-polar, which means they can go on either direction.

Please note the last pin is just there to provide a 'key' mechanism to SHOW you where they go.Quote from: Fireborn on July 21, 2009, 06:41:13 PM
