4. Remove the circled thumb-screw; this will be
used to secure the PCIe card's bracket to the
inner chassis. If you are using a double-width
card, please remove the additional thumb-screw
and bracket cover as well.
5. Install the PCIe card. Line up the connector
on the card with the PCIe slot (highlighted in
red), and make sure that the edge of the metal
bracket on the PCIe card lines up with the slot in
the bottom of the Mercury Helios 3S. The card
shown is an example of a single-width, half-
length, full-height card. Your card's dimensions
and appearance may differ.
6. Once the PCIe card is fully seated, the PCIe
bracket will sit flush with the opening on the
back of the inner-chassis. Take the screw you
removed in Step 4 and secure the PCIe card
bracket to the Mercury Helios 3S.
