5.2 Installation Steps

1. Prepare your computer: Power down your HP EliteDesk or ProDesk system and unplug all cables.
2. Open the computer case: Refer to your computer's service manual for instructions on how to safely open the case.
3. Locate an available expansion slot: Identify the appropriate slot for your specific expansion card (e.g., PCIe slot for NIC cards, or dedicated slots for port expansion cards).
4. Insert the card: Carefully align the card with the slot and press down firmly until it is securely seated. Do not force the card.
5. Secure the card: Use the retaining clip or screw to secure the card in place within the chassis.
6. Close the computer case: Reassemble the computer case according to your computer's service manual.
7. Reconnect cables: Plug in all necessary cables, including power, monitor, and peripherals.
8. Power on the computer: Start your computer. The operating system should detect the new hardware.
9. Install drivers (if necessary): For some cards, especially NICs or advanced display adapters, you may need to install specific drivers. Check the manufacturer's website for the latest drivers compatible with your operating system.

6. Operation

Once successfully installed and recognized by your operating system, the expansion card will function automatically. For example:

• USB/Type-C cards: Connect your USB devices to the new ports.
• HDMI/VGA/DP cards: Connect your display devices to the new video output ports.
• 2.5GbE NIC cards: Connect an Ethernet cable to the new RJ45 port for network access.
