Hardware Installation
This chapter describes the PCI Express Series hardware installation procedure. Since the
BIOS automatically assign the PCI Express board’s IRQ number and I/O addresses, you must
plug in the board before installing the driver.
Step 1
Connect the internal cable to the card
Note
Both sides of the cable connectors are the same, it doesn’t matter which side
you connect

7
Step 2
Install the card to the Mini PCI-e slot
Make sure you install the card in the right position (fool-proof design)
Step 3
Fix the card on the motherboard
Make sure you tighten up the screws to fix the card

8
Step 4
Card installation completed
Step 5
Connect the cable to the daughter board
Connect other side of the cable to the daughter board
Note
Both sides of the cable connectors are the same, it doesn’t matter which side
you connect
