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’sOwner’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.

Turning Off Your Indy Workstation

Turning Off Your Indy Workstation
Press and release the power button on the front of the workstation, as shown
in Figure 1, to power off the system.
Note that it’s not necessary to shut down the system software before
pressing the power button.
Figure 1 Turning off the Indy workstation
The notifier shown in Figure 2 appears on your screen within a few seconds
and the LED blinks green and amber. Then the system powers off
automatically within the next minute.

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.

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:

1. Put the wrist strap over your wrist, making sure it is tight against your
arm.
2. Attach the alligator clip to a metal part of the Indy chassis.
Checking Your System’s PROM Version: R4600PC 133 MHz Upgrade
If you are installing the R4600PC 133 MHz CPU, you may or may not need
to replace your system’s PROM chip, depending what PROM version you
have.
Note: For other CPU upgrades, you must replace the PROM, and do not
need to check the PROM version first. Go to the next section, “Replacing the
PROM Chip”on page 8.
You check the version of the PROM chip from the Command Monitor while
shutting down your system.
Follow these steps to check your system’s PROM version:
1. Shut down the system.
■From the System toolchest in the upper left corner of your screen,
choose “System Shutdown.”
After a few seconds you see a cautionary message about stopping
all running applications.
■Click “OK”to shut down without powering off the system.
You see the message shown in Figure 4.
Figure 4 Okay to Power Off Notifier
■Click the “Restart”button.

You then see the message shown in Figure 5.
Figure 5 Starting Up the System Notifier
■Click on the “Stop for Maintenance”button. The System
Maintenance menu appears.
2. Press 5on the keyboard, or click on the “Enter Command Monitor”
icon on the System Maintenance menu.
3. See what version of the PROM you have. At the >> prompt, type:
version
Then press <Enter>.
You see a line similar to this:
PROM Monitor SGI Version 5.0 Rev B6 IP24 Sept 28, 1994 (BE)
The date, “Sept 28, 1994”tells you the version of the PROM.
•If your PROM is dated Sept 28, 1994 or later, you do not need to
replace the PROM chip. Skip the section “Replacing the PROM
Chip”, and go to “Replacing the CPU Module”on page 23.
•If your PROM is dated before Sept 28, 1994, you must replace the
PROM chip. Go to the next section, “Replacing the PROM Chip”on
page 8.
4. Type exit to exit the PROM monitor.

Upgrading the Indy Workstation CPU
Replacing the PROM Chip
To reach the PROM chip, you must first remove any GIO option boards that
are installed and then remove the graphics board. Follow the steps below.
Removing the GIO Option Board
GIO option boards are installed on top of the graphics board. A single-width
GIO option board covers half of the graphics board; a double-width covers
the entire graphics board. Figure 6 shows a single-width board.
To determine if your workstation has a GIO option board installed, look at
your workstation and at Figure 6. If there is a GIO option board installed,
follow these steps to remove it. If there is no GIO option board installed, skip
to “Removing the Graphics Board”on page 10.
Note: These instructions are for a single-width GIO option board. Use the
same steps to remove a double-width GIO option board. The only difference
is that there are more screws to remove on a double-width board.

1. Locate the GIO option board, as shown in Figure 6.

2. If there are external cables connected to the GIO option board connector
on the rear of the workstation, disconnect them.
3. Using the Phillips screwdriver provided with this upgrade kit, remove
the two screws from the GIO board connector on the rear of the
workstation, as shown in Figure 7.

Before removing the PROM chip, familiarize yourself with it. Note that it has
either a semi-circular notch or a small, indented circle at one end. You’ll use
this notch or circle to orient the upgrade PROM when you install it.
