Installation—Xserve G4 with Tray Load CD-ROM
This section covers the installation of the Encore/MDX G4 Duet into
an Xserve G4 server with a tray load CD-ROM mechanism. These
models can be identified by the CD tray door on the front right cor-
ner of the server. If you are installing this product into an Xserve with
a slot load CD mechanism, go to page 10. 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
1. Remove the plastic shroud covering the processor card’s heat sink
(Figure 16).
2. Remove the three screws securing the processor card heat sink to
the logic board (Figure 17).
3. Lift the heat sink off the processor card and set it aside
(Figure 18).
4. Grasping its edges, gently lift the side of the processor card oppo-
site the fan to separate it from the logic board, and then carefully
lift it straight up and away
(Figure 19). Set the card aside.
