J41 is an LED INPUT. The idea is to run a wire from the activity LED output header of any plug-
in HD controller card (e.g. a RAID card) to the motherboard, so that the card's LED can be
"combined " with the IDE and SCSI activity indicators on the motherboard and then driven to the
J40 HD LED output. In other words, when a card's LED lights up, so will the front-panel hard-disk
activity indicator. This is useful for chassis that have only a single LED to indicate HD activity from
multiple controller sources. (Pin 1 = negative terminal of the add-on card's LED header, Pin 2 = do
not connect.)
