3. Setup and Installation
Before proceeding with installation, ensure your computer is powered off and unplugged from the wall outlet. It is recommended to wear an anti-static wrist strap to prevent damage to components.
- Open the Computer Case: Carefully remove the side panel of your computer case to access the motherboard and expansion slots.
- Identify Available USB 2.0 Headers: Locate two available 9-pin USB 2.0 headers on your motherboard. These headers typically have 9 pins arranged in two rows, with one pin often missing or blocked to ensure correct orientation. Consult your motherboard manual for exact locations if needed.
- Remove an Expansion Slot Cover: Identify an empty expansion slot at the rear of your computer case. Remove the metal cover corresponding to this slot.
- Install the Bracket: Insert the metal bracket of the JacobsParts USB 2.0 4 Port Rear Panel Bracket into the open expansion slot. Secure it with a screw, typically found on the computer case.
- Connect to Motherboard Headers: Carefully connect the two 9-pin header cables from the bracket to the identified USB 2.0 headers on your motherboard. Ensure the connectors are oriented correctly to avoid bending pins. Each 9-pin connector on the cable will connect to one 9-pin header on the motherboard, providing two USB 2.0 ports per header.
- Close the Computer Case: Once the cables are securely connected and the bracket is fastened, replace the side panel of your computer case.
- Power On: Reconnect your computer's power cable and power it on. The new USB 2.0 ports should be automatically detected by your operating system.
