Antec Plus 550, Solo White Connecting the Front I/O, Connecting the USB Ports, Signal Names

1.Make sure you have the correct I/O panel for your motherboard. If the panel provided with the case isn’t suitable, please contact your motherboard manufacturer for the correct I/O panel.

2.Line up your motherboard with the standoff holes, and remember which holes are lined up. Not all motherboards will match with all the provided holes; this is normal, and won’t affect functionality. (In other words, there will likely be extra holes.)

3.Remove your motherboard by lifting it up.

4.Screw the brass standoffs into the threaded holes that line up with your motherboard. Do not over-tighten the standoffs. Some standoffs may be pre-installed for your convenience.

5.Place your motherboard on the brass standoffs.

6.Fasten your motherboard to the standoffs with the provided Philips-head screws. Your motherboard is now installed.

Connecting the Front I/O

1.Connect the Reset switch (labeled RESET SW) to the motherboard at the RST connector. Polarity (positive and negative) does not matter for switches.

2.Power Switch (labeled POWER SW) connects to the PWR connector on the motherboard.

3.Connect the Power LED (labeled POWER LED) to your motherboard. For LEDs, colored wires are positive (+). White or black wires are negative

(–). If the LED does not light up when the system is powered on, try reversing the connection. For more info on connecting LEDs to your motherboard, see your motherboard manual.

4.Hard Drive LED (labeled HDD LED) connects to the hard drive activity header.

Connecting the USB Ports

You will find a single 10-pin connector on a cable attached to the front USB ports. This is an Intel® standard connector that is keyed so that it can’t be accidentally reversed when connected to a proper Intel® standard motherboard header. Connect the 10-pin connector to the motherboard headers so that the blocked pin fits over the missing header pin.

Note: Please check the motherboard manual for the USB header pin layout and make sure it matches the table below. If it does not match this Intel® standard, please visit Antec’s web store at http://www.antec.com/StoreFront.bok and search for part number 30095 to order a USB Internal Adapter Cable. This adapter will allow you to connect the front USB to your motherboard on a pin-by-pin basis.
