vii General Overview

We strongly recommend reading through this entire manual if this is your ﬁrst time installing a processor upgrade card in the Power Mac G4 Cube. The Power Mac G4 Cube is a compact marvel of Apple engineering. Although it was never intended for the Cube’s processor to be upgraded, Sonnet’s Torx T-15 screws (for cooling fan) engineers have created the Encore/ST G4, a processor upgrade solution designed to deliver advanced Torx Torx processing power to the Cube. T-10 T-15 tool tool You Should Have The following items should be included in your product package (see Figure 1): • Cooling fan • Four 20mm Torx T-15 screws (for cooling fan) • Sonnet Torx T-10 tool (for Cube screws) Cooling fan • Sonnet Torx T-15 tool (for fan screws) Figure 1 The following items are required for installation: • Encore/ST G4 processor upgrade card, (sold separately) Top plate • Mac OS 9.2.1 minimum (required for ﬁrmware release latch update procedure) • Power Mac G4 Cube Firmware version 4.1.9 (min.) • Tweezers • Four small containers to separate screws removed from the Cube (recommended) core

Prior to beginning the hardware installation of the Encore/ST and cooling fan, you MUST ﬁrst posts (4) perform any necessary Mac OS software upgrade and ﬁrmware update to your Cube as explained in the software installation chapter that follows. enclosure

Operating System Compatibility At this printing, Encore/ST G4 processor upgrade cards are compatible with Mac OS 9.2.x through Mac OS X version 10.2.2. For up-to-date Mac OS compatibility, check our website. viii Cube Hardware Features Figure 2 Prior to proceeding with the software and hardware installation of the Encore/ST card and cooling fan, you should become familiar with some basic Cube hardware features (Figure 2). Due to its compact and complex design, there are Screw Types numerous screws of different types (Figures 3 and 4) that must be removed, and then reinstalled in the proper places. In order to replace the processor card and install the fan, you will need to remove several components. Most of the computer will be disassembled during the course of this upgrade #1 #2 #3 #4 process. Do not proceed with this installation unless you (Qty: 11) (Qty: 1) (pan head, (Qty: 2) Qty: 1) feel comfortable with completely disassembling your Cube. Sonnet strongly recommends that a qualiﬁed technician perform this installation.

As you proceed with disassembling the Cube in the hardware installation of the Encore/ST, we recommend that you place the screws in separate containers to help you to easily identify and keep track of them. This will minimize confusion during reassembly. #5 #6 #7 (supplied by (Qty: 2) (Qty: 1) Sonnet, Qty: 4) Before working inside your Cube, always move it to an area where you can freely work, and gently rest it Figure 3 on a soft cotton cloth to prevent scratching the computer’s enclosure.

Troubleshooting Guide

Problem: Using the power switch on top of the Cube, the computer won’t turn on.

Possible Solution: Remove the core from its enclosure, and then remove the eight screws securing the top plate. Lift up the top plate and verify the small, white 5-pin connector (wires leading from the DC-to-DC board plugged into the main logic board) is plugged in securely to the the sensor switch.

Problem: There are extra Torx screws left after reassembling the Cube.

It is easy to miss a screw when you reassemble the computer.
