Replacement Instructions  
Follow the instructions in this sheet carefully. Failure to follow these instructions could  
damage your equipment and void its warranty.  
Note: Written and video instructions covering customer-installable parts are available at  
Tools Required  
#2 Phillips screwdriver  
Opening the User Access Door  
1. Save all open documents and quit all open applications.  
2. Turn the computer off by choosing Shut Down from the Special menu (if using Mac OS  
9), or choose Shut Down from the Apple menu (if using OS X).  
3. Unplug all cables, except the power cord, from the computer. (Figure 1)  
Warning: If the internal modem is connected to a telephone line, disconnect the  
telephone line from the internal modem port before you open the user access door.  
This prevents electric shock.  
Figure 1  
6. Important: To avoid electrostatic discharge, always ground yourself by touching  
metal before you touch any parts or install components inside the computer. To avoid  
generating static electricity, do not walk around the room until you have finished  
installing the memory and closed the computer.  
Touch the metal surface on the back of the computer. (Figure 3) This helps protect the  
computer from damage caused by electrostatic discharge.

Installing Memory  
RAM Expansion Module Specifications  
The RAM expansion modules used in the eMac and eMac (ATI Graphics) computers are  
168-pin SDRAM DIMMs (dual inline memory modules) that are 3.3 V, unbuffered, 8-byte,  
non-parity, PC-133 compliant.  
The RAM expansion modules used in the eMac (USB 2.0) computers are 184-pin SDRAM  
DIMMs (dual inline memory modules) that are 2.5 V, unbuffered, 8-byte, non-parity, and  
PC2700 compliant. The speed of the SDRAM devices must be rated at 167 MHz (7 ns) or  
faster.  
Important: The memory expansion cards (DIMMs) must use SDRAM devices as  
specified above. DIMMs for previous models of eMac or DIMMs that use EDO or SGRAM  
devices will not work. If they are installed, the computer will beep, and the power light will  
flash several times when you turn on the computer. This indicates that the computer  
cannot find any useable RAM.  
Procedure  
1. Remove the replacement memory from its static-proof bag, taking care not to touch  
the connectors or chips.  
2. Push down the ejectors on the slot of the memory module you want to install or  
replace memory. (Figure 5)

3. Align the replacement memory module in the memory slot, apply pressure evenly to  
both top corners, and push the memory into the slot until the ejectors lock it into place.  
(Figure 6)  
Warning: The memory is designed to fit into the slot only one way. Be sure to align  
the notches in the memory module with the small ribs inside the slot.

2. Carefully turn the computer right side up.  
3. Reconnect the power cable. Important: When connecting the power cord, first plug  
the cord into your eMac, then plug the other end into an electrical outlet or power strip.  
4. Press the power button to restart your computer.  
Warning: Never turn on the computer unless all of its internal and external  
parts are in place and it is closed. Operating the computer when it is open or  
missing parts can damage your computer or cause injury.
