Eagle 450 Upgrade Instructions, Rev. A00
Chapter 7 - Eagle 300/500 Upgrade
Hardware Installation
In this upgrade the AM-138 replaces the AM-172 or AM-174 Roadrunner board and the AM-319 system
board. This upgrade procedure involves removing these two boards and the rear panel and installing the
AM-138 and a new rear panel. The following instructions walk you through this process.
PREPARING FOR THE UPGRADE
Before starting the hardware upgrade, make sure you have completed all of the steps in Chapter 5,
"Beginning an Eagle 450 Upgrade." Do not begin the hardware installation until you've performed all of
the necessary preliminary processes.
While your computer's hardware is exposed and the AC power cord is unplugged, the
components are vulnerable to damage caused by static discharge. Your body and clothing are
capable of storing an electrical charge that can damage or destroy unprotected electronic
components. Before you handle any computer hardware, make certain your work area is properly
protected against static discharge. There are a number of commercially available static protection
devices, like the wrist strap shown in Chapter 3, designed specifically to protect your equipment
from harmful static discharge.
REMOVING THE CHASSIS COVER
1.
Power down your computer and unplug the power cord.
2.
Label and unplug all external cables.
3.
At the rear of the computer, remove the four screws that attach the top cover to the chassis.
4.
Slide the top cover back and lift the rear edge up (as indicated by the arrows on Figure 7-1).
Remove the cover and place it out of the way.
The pictures in this chapter show the chassis used for most Eagle computers. Your chassis may
look slightly different, but the installation procedure is the same.
