Prepare Encore/MDX G4 Duet for Installation
Before you install the Duet processor upgrade into your Xserve, you
must remove the attached fan assembly; they are not used when this
upgrade is installed in an Xserve.
1. Remove the Encore/MDX G4 Duet processor upgrade card from
its anti-static package; make sure to handle the card by its edges
(Figure 20).
2. Carefully remove the cap covering the connector on the bottom
of the Duet card (Figure 21), and then place the cap on the origi-
nal processor card’s connector.
3. Place the processor card you removed from the computer into
the anti-static package, and then store it, the original heat sink,
and the screws you removed, in a safe place.
4. Place the Duet card on a flat, level surface, with the bottom of
the card resting on the piece of foam that was in the anti-static
package. Remove the four screws securing the fan assembly to
the top of the card and set them aside
(Figure 22).
5. Carefully disconnect the fan connector from the Duet card, and
then remove the fan assembly (Figure 22).

Support Note: Sonnet recommends that you keep the original
processor card, heat sink, and screws in case you ever need them.
WARNING: Do not change the position of the DIP switches
on the top edge of the Duet card; they must be left in the
Up position. If they are set to the down position, your Xserve will not
boot with the Duet card installed.
