When swapping to a modern aftermarket computer case, you will be met with separate 2-pin female connectors. Wire them to the individual header pins using the configuration below: Pin Number Function / Label Polarity / Note Hard Drive Activity LED (HDD_LED) Positive (+) Pin 2 Power Indicator LED (PWR_LED) Positive (+) Pin 3 Hard Drive Activity LED (HDD_LED) Negative (-) Pin 4 Power Indicator LED (PWR_LED) Negative (-) Pin 5 Reset Switch (RESET_SW) No Polarity Pin 6 Power Switch (PWR_SW) No Polarity Pin 7 Reset Switch (RESET_SW) No Polarity Pin 8 Power Switch (PWR_SW) No Polarity Pin 9 Unused / Reserved Ground / Empty Pin 10 Key Pin Physically Missing Pin 11 Unused / Reserved Ground / Empty Pin 12 Local Network LED (LAN_LED) Positive (+) (Rarely used in custom builds) Pin 13 Unused / Reserved Ground / Empty Pin 14 Local Network LED (LAN_LED) Negative (-) Step-by-Step Connection Instructions
Ensure your power supply switch on the back of the case is turned ON (I position) and the 24-pin ATX main power cable is fully seated.
| Pin # | Signal | Standard Wire Color (Most Cases) | | :--- | :--- | :--- | | 1 | HDD_LED (+) | Orange | | 2 | PWR_LED (+) | Green | | 3 | HDD_LED (-) | White | | 4 | PWR_LED (-) | White |

The front panel header is typically found in the of the board. It consists of two rows of pins. The row closest to the edge of the motherboard is the EVEN numbered row (2, 4, 6, 8...), while the row closer to the center (next to the PCIe slots) is the ODD row (1, 3, 5, 7...). Polarity Notes HDD LED 1 (+) & 3 (-) Connect the colored wire to Pin 1. Power LED 2 (+) & 4 (-) Sometimes marked as PWR_LED. Reset Switch Polarity does not matter for switches. Power Switch The "on" button; polarity does not matter. LAN LED Side-oriented pins, specific to some case designs. Connection Tips for New Cases
user wants a long article about the front panel header for the Acer IPISB-VR Rev 1.01 motherboard. This is a common OEM motherboard from Acer, often found in Aspire desktops. The article needs to be comprehensive, covering how to locate the header, pinout, standard vs. proprietary designs, how to connect case front panel cables (power switch, reset switch, HDD LED, power LED), and troubleshooting. I need to search for relevant information. I will perform a set of searches to gather information. search results show some potentially useful links. Result 0 from Tom's Hardware might contain pinout information. Result 1 from salsalasopa860.weebly.com might have a manual or pinout. Result 2 from xpressskiey.weebly.com might have a manual. Result 5 from forum-monitor.net.ru is in Russian but might have pinout. Result 3 from Tom's Hardware might be relevant. Result 0 from gutefrage.net is in German but might be helpful. I should open these to gather detailed information. Tom's Hardware thread provides a pinout solution: "HD LED (orange) +1 -3 PWR LED (green) +2 -4 RESET (blue) 5 7 PWR ON (RED) 6 8". This seems to be a key source. The salsalasopa860.weebly.com page also provides a layout: "HDD LED 1 (+), 3 Power LED 2 (+), 4 Reset SW 5 (+), 7 Power SW 6 (+), 8". The xpressskiey.weebly.com page seems to be a similar complaint about missing manuals, not a pinout. The forum-monitor.net.ru page is in Russian and might not contain a clear pinout. The gutefrage.net page offers general advice. I should also search for "IPISB-VR front panel pinout diagram" and "Acer IPISB-VR front panel header pinout". I will also search for "IPISB-VR Rev 1.01 front panel connector" and "Acer IPISB-VR front panel audio header". search results show some user queries and forum posts. The Tom's Hardware thread (result 0) might have the pinout. The sweclockers.com thread (result 1) might have a diagram. I should open result 0 from the search for "IPISB-VR Rev 1.01 front panel". I also need to open result 1 from the search for "acer ipisb-vr rev 1,01 är det någon som har kopplingsschemat?". search results provide some pinout information. The Tom's Hardware thread gives a pinout: HD LED (orange) +1 -3, PWR LED (green) +2 -4, RESET (blue) 5 7, PWR ON (RED) 6 8. The salsalasopa860.weebly.com page gives: HDD LED 1 (+), 3 Power LED 2 (+), 4 Reset SW 5 (+), 7 Power SW 6 (+), 8. There are also mentions of a schematic or boardview file. The article should cover the motherboard's background, the challenge of finding documentation, the location of the front panel header, pinout details, step-by-step connection guide, troubleshooting, and FAQs. I will also need to gather information on the motherboard's specifications, such as chipset, form factor, and other headers. I can search for "Acer IPISB-VR Rev 1.01 specifications". should also search for "Acer IPISB-VR front panel header location". search results have provided some pinout information. I should also look for a schematic or boardview file. Result 1 from search 11 (realschematic.com) might have a schematic. I should open that. schematic is a paid product, but the page confirms the motherboard's existence and the project name. For the article, I should also include basic front panel connection principles, such as polarity for LEDs and the non-polarity of switches. I should also mention that the front panel header is often labeled "F_PANEL" or "PANEL1". I can search for "front panel header pinout standard". should also gather information on potential issues, such as the system not powering on, LEDs not working, or reset button not functioning. I can search for "IPISB-VR front panel not working". article should be comprehensive and well-structured. I will now produce a long article covering the motherboard's background, the challenge of documentation, locating the header, pinout diagrams, step-by-step connection guide, troubleshooting, and FAQs. I will cite the sources I've found.ating a pre-built desktop motherboard can be a daunting task, especially when looking for official documentation. If you own an Acer system, you've likely experienced the struggle of finding a simple pinout diagram. This guide serves as the complete resource for connecting the front panel of a PC case to the Acer IPISB-VR Rev 1.01 motherboard.
Note: Pin 1 is often marked by a or a small "1" printed on the motherboard silkscreen. Pin 10 is usually missing to serve as a "key" for orientation. Connection Tips When swapping to a modern aftermarket computer case,
Note: Pinout diagrams for Acer boards vary slightly by manufacturing date. Always verify with a multimeter if possible.
: Pin 1 requires the positive wire. Look for a small triangle icon molded onto the back of the plastic connector to verify which wire is positive. 4. Map the Reset Switch (RESET_SW) Action : Attach the RESET_SW cable to Pin 5 and Pin 7 .
Leave a comment with your specific case model or the color of wires on your front panel connector, and we will map them for you. This link or copies made by others cannot be deleted
If the computer runs fine but the front panel lights remain dark: Turn off the PC and unplug the power cable.
If you are moving this motherboard to a new case, the standard individual 2-pin connectors from the new case must be plugged in vertically (e.g., bridging pins 1 and 3) according to the diagram above.
By following this guide, you should now have all the information you need to confidently connect your case's front panel to your Acer IPISB-VR Rev 1.01 motherboard and get your PC up and running.
On the IPISB-VR Rev 1.01, the header is usually read from left to right, with the bottom row typically handling the critical power and ground signals. The most common configuration for this revision is as follows:
