Installation—Xserve G4 (Slot Load) Models
This section covers the installation of the Encore/MDX G4 Duet into
an Xserve G4 (Slot Load) server. These models can be identified by the
CD slot on the front right corner of the server. If you are installing this
product into an Xserve with a tray load CD mechanism, go back to
page 7. If you are installing this product into a Power Mac G4 Mirrored
Drive Doors (MDD) model, go back to page 3.
Shut Down and Remove Server from its Rack
1. Shut down your Xserve. If the server has been on for a while,
allow a few minutes for it to completely cool before beginning
the installation.
2. Disconnect any connected cables and remove the Xserve from
its rack. Place the Xserve on a flat, level surface, and then recon-
nect the power cord to the server and an electrical outlet.
3. Touch the metal enclosure to discharge any potential damaging
static electricity.
4. Disconnect the power cord from the Xserve.
Remove Processor Card Assembly
1. Remove the three screws securing the processor card assembly to
the logic board (Figure 28).
2. Grasping its edges, gently lift the side of the processor card
assembly opposite the fan to separate it from the logic board, and
then carefully lift it straight up and away
(Figure 29). Set the
assembly aside.
Prepare Encore/MDX G4 Duet for Installation
Before you install the Duet processor upgrade into your Xserve, you
must replace the attached fan assembly with the included heat sink
cover, and set the DIP switches on the top surface of the card to
ensure full system performance.
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 30).
2. Carefully remove the cap covering the connector on the bottom
of the Duet card (Figure 31), and then place the cap on the origi-
nal processor card’s connector.
WARNING: When handling computer products, take care to
prevent components from being damaged by static electricity;
avoid working in carpeted areas. Handle processor upgrade cards only
by their edges and avoid touching connector traces and component
pins. Also, avoid touching the logic board and any of its components.
Support Note: To avoid generating a static charge in your
body, do not walk around the room until after you finish
installing the Encore card and close the computer.
