Chapter 3: Installing HDX Cards 13
9 Install the first HDX card into the lowest-num-
bered available PCIe slot in the computer. (See
Figure 4 on page 14).
Do the following:
• Hold the card above the PCIe slot at a slight
angle so that the back of the card is higher
than the front of the card (where the Di-
giLink Mini connectors are located on the
card).
• With the card at an angle, rest the card’s
front bracket against the edge of the chas-
sis, where the computer’s slot access port is
located.
• Carefully slide the back of the card down
into the PCIe slot’s grey plastic PCIe card
support (where the slot numbers appear).
(See Figure 5 on page 15.)
• With the card PCIe connectors facing down,
carefully slide the card straight down and
firmly seat the PCIe connector into the
PCIe slot, making sure that all card compo-
nents on the back of the card have clearance
from the grey plastic PCIe card support.
On Mac Pro “Westmere” machines, you may
need to carefully push the grey plastic PCIe
card support back to install the HDX PCIe
card without damaging it.
Do not force the card into the PCIe card
support slot. When you have the correct
installation angle, the card should slide in
easily. If you do not have the correct angle,
reposition the card.
