Installing a Mini PCIe Card
Note:
The system also has a half-size Mini PCIe slot that can accommodate either a Mini PCIe or an mSATA
card. Refer to jumper settings for signal selection for this slot.
The system board is equipped with 2 Mini PCIe slots: one full-size and one half-size slot. Here we will
demonstrate the installation of a full-size Mini PCIe card.
1. Grasp the Mini PCIe card by its edges and align the notch in the connector of the PCIe card with
the notch in the connector on the system board.
2. Push the Mini PCIe card down and use the provided mounting screw to secure the card on the
system board.
