Antec Sonata III 500 - Manual (Page 3)

INSTALLING THE MOTHERBOARD
This manual does not cover CPU, RAM, or expansion card installation. Please consult
your motherboard manual for specific mounting instructions and troubleshooting.
1.
Lay the case down, with the open side facing up. The drive cages and power
supply should be visible.
2. 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.
3. 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 functionally. (In other words, there will likely be
extra holes.)
4. Remove your motherboard by lifting it up.
5.
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.
6. Place your motherboard on the brass standoffs.
7.
Screw in your motherboard to the standoffs with the provided Philips-head
screws. Your motherboard is now installed.
Connecting the Power and LED
If the motherboard has a 20-pin power receptacle, detach the 4-pin attachment on
the 24-pin power connector, see pictures 1 and 2. Before you connect the power
supply to any of the devices, please consult the appropriate user manuals for the
motherboard and other peripherals.
1.
Connect the 24-pin Main Power Connector and
the 4-pin or 8-pin 12V connector to the motherboard
as needed. If the motherboard uses a 20-pin
connector, detach the 4-pin attachment on the
24-pin power connector (see pictures 1 and 2).
Note: the detachable 4-pin section cannot be
used in place of a 4-pin +12V connector.
2. Connect the Reset switch (labeled RESET SW) to
the motherboard at the RST connector. Polarity (positive and negative) does
not matter for switches.
3. The Power Switch (labeled POWER SW) connects to the PWR connector on
the motherboard.
4. The Power LED (labeled POWER LED) connector is located behind the Reset
connector. 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.
5. The 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 your motherboard headers so that the blocked pin fits over
the missing header pin.
