Upgrading the Indy Workstation CPU

This manual explains how to install the CPU upgrade on an Indy
workstation.

Note: If you received a CD with the upgrade, you must install the software

first. Read the software release notes on the CD for software installation
instructions before installing the hardware.

To install the hardware, you will complete these steps:

• Shut down the system.

• Remove the cover.

• Remove and replace the PROM chip on the system board. (If you are

upgrading to an R4600PC 133 MHz CPU, you may not have to replace
the PROM. See the section “Checking Your System’s PROM Version:
R4600PC 133 MHz Upgrade” on page 6.)

• Remove and replace the CPU module.

• Replace the cover and restart your system.

Read through this guide first before starting the upgrade. If you find a term
you haven’t seen before, see your workstation’s Owner’s Guide. The glossary
contains definitions of many of the terms used in this guide.

Caution: Make sure you have a full backup of your system before powering

down and installing the upgrade. For instructions on backing up your
system, choose “Online Books” from the Help toolchest. Then select the
Personal System Administration Guide and search for “Backing Up and
Restoring Files.”

Installing the Software

If you received a CD with the upgrade, read the release notes on the CD for
instructions on installing the software. Install the software before installing
the hardware.

Upgrading the Indy Workstation CPU

Removing the Top Cover

Follow these steps to remove the top cover of your Indy workstation:

1. If the monitor is on top of the workstation, move it to one side.

Caution: Monitors are very heavy. Have someone help you move it.

2. Disconnect the following cables from the back of the Indy workstation:

• power cable

• monitor cable

• IndyCam™ cable (if connected)

• EtherNet AUI cable (if connected)

Disconnecting the IndyCam and EtherNet AUI cables is optional.
Removing them gives you more room when removing the screws on
either side of the graphics board connector.

Removing the Top Cover

3. Facing the front of the Indy workstation, place your right thumb on the
small channel at the back of the cover, and your second and third
fingers under the finger ledge, as shown in Figure 3.

4. Snap the cover loose by bracing your thumb against the lip and
pushing up the finger ledge with the second and third fingers, followed
by a small push toward the front.

5. Slide the cover forward about one inch and tilt it up to remove it.

Tip: It may be difficult to release the cover the first time, and you may have

to use some force.

Attaching the Wrist Strap

Wear the wrist strap to prevent the flow of static electricity, which can
damage the components in the Indy workstation.

Caution: The components inside the Indy are extremely sensitive to static

electricity. Handle all chips and modules carefully, and wear the wrist strap
shipped with the upgrade package while replacing parts inside the system.

To attach the wrist strap, follow these steps:
