Acer IPISB-VR Rev 1.01 motherboard, commonly found in the Acer Aspire M3970 and Gateway DX4860, uses a standard but sometimes unlabeled front panel header. Use the following pinout to connect your case cables correctly. Front Panel Header Pinout
Locate the cluster of pins usually found on the bottom-right edge of the motherboard. Pin 1 is typically marked by a white square on the PCB. Pin Numbers Description
Hard Drive activity light. Pin 1 is Positive (+), Pin 3 is Negative (-).
Power status light. Pin 2 is Positive (+), Pin 4 is Negative (-). Reset Switch Resets the PC. Polarity does not matter for switches. Power Switch Main power button. Polarity does not matter.
Network activity indicator (often unused by standard cases). Important Connection Tips Missing Pin:
Pin 10 is typically missing from the header to help with orientation. LED Polarity:
do not light up, flip the connector 180 degrees. LEDs only work in one direction. Positive (+) Identification: Look for a small
or arrow on the back of the plastic connector to identify the positive wire.
The Power and Reset switches are non-polarized, meaning they will work regardless of which way the connector is facing. Other Front Panel Connections Explaining PC Front Panel Connectors 23-Oct-2022 —

Disclaimer: Always disconnect your power supply before working on your motherboard. This guide is based on reverse engineering and community testing. Revisions of the IPISB-VR (1.00, 1.01, 1.02) may have minor pinout differences—always test with a multimeter if unsure.
The front panel header for the Acer IPISB-VR Rev 1.01 is a standard Acer OEM 14-pin header (with one pin missing). If you are moving this motherboard to a new case, you will likely need to connect individual 2-pin cables (Power SW, Reset, etc.) to this specific pinout. Front Panel Pinout Diagram
The pins are arranged in two rows. Row 1 (Odd) is typically closer to the center of the board, and Row 2 (Even) is closer to the edge. Acer Community Description 1 (+) / 3 (-) Indicates hard drive activity (Polarity matters) 2 (+) / 4 (-) Constant light when system is ON (Polarity matters) Connects to the Reset button (Polarity doesn't matter) Connects to the Power button (Polarity doesn't matter) Key / Reserved No pin (Empty space) Key / Reserved No pin (Empty space) Indicates network activity (Often sideways) Connection Quick-Guide Identify Pin 1
: Look for a white square or small "1" printed on the motherboard silkscreen. Power SW (Pins 6 & 8) Reset SW (Pins 5 & 7)
are not polarized. You can plug them in either way, and they will work as long as they bridge the correct two pins. HDD LED (Pins 1 & 3) Power LED (Pins 2 & 4)
are polarized. If they do not light up after booting, simply flip the connector 180 degrees. USB & Audio
: These are separate from the front panel button header. USB headers are typically yellow with 9 pins, while the Front Panel Audio Header is usually located near the back I/O ports. Acer Community Acer IPISB-VR Rev 1

Acer IPISB-VR Rev 1.01 front panel header is a 14-pin (actually 13 physical pins, with one missing) connector typically located at the bottom-right edge of the motherboard
. Because this board is often found in OEM systems like the Gateway DX4860, it lacks a standard retail manual, but the pinout follows a specific layout.

: Pin 10 is missing from the header. This "key" helps you orient the block if you are using the original OEM single-block connector. LED Polarity
: LEDs (HDD and Power) are polarized. If they do not light up after connection, flip the 2-pin connector around. Identifying Positive (+)
: On your case cables, the positive wire is usually colored (red, green, or blue), while the negative wire is typically black or white. You can also look for a small triangle (▲)
on the back of the plastic connector, which indicates the positive side.
: The Power and Reset switches are "momentary" switches and work regardless of which way the pins are facing. Acer Community

The Acer IPISB-VR Rev 1.01 is a micro-ATX motherboard commonly found in OEM systems like the Acer Aspire M3970 and Gateway DX4860. Because it is an OEM board, finding an official manual for the front panel header can be difficult, as these systems often use proprietary single-block connectors. Front Panel Header Pinout (JFP1)
The front panel header on this board is typically a 14-pin or 10-pin block located near the bottom right edge. The pins are numbered in an alternating fashion: even numbers on one row and odd numbers on the other. Connection Description 1 HDD LED + Hard Drive Activity Light (Positive) 2 Power LED + Power Indicator Light (Positive) 3 HDD LED - Hard Drive Activity Light (Negative) 4 Power LED - Power Indicator Light (Negative) 5 Reset SW Reset Switch Not Polarized 6 Power SW Power Button Not Polarized 7 Reset SW Reset Switch (Ground) Not Polarized 8 Power SW Power Button (Ground) Not Polarized 10 Empty Key Pin (Missing) 12 LAN LED + Network Activity Light (Positive) 14 LAN LED - Network Activity Light (Negative) Key Installation Tips
Identifying Pin 1: Look for a white square or a small "1" printed on the motherboard's silk-screen near the corner of the header.
Polarity Matters for LEDs: If your HDD or Power LED does not light up, reverse the connector on the pins. Reversing LED polarity will not damage the board.
Switches are Universal: The Power and Reset switches are "momentary" and do not have a specific positive or negative orientation.
Testing without a Case: You can start the motherboard by briefly touching a screwdriver to pins 6 and 8 (Power Switch). General Specifications Explaining PC Front Panel Connectors
