About Memory
The Octane workstation has four DIMM banks with two DIMM sockets in each of the
banks. Before you install the two 1 GB DIMMs, review the following information:
•Bank 1 (sockets 1 and 2) must always be filled.
•The highest density DIMMs must be installed in Bank 1, while lower density
DIMMs must be installed in the remaining banks by order of their size (highest
density first).
•Banks must be filled sequentially; when Bank 1 is full, fill Bank 2. Do not skip banks.
•Each bank must be empty, or contain two DIMMs, one in each of the two sockets.
•Capacity refers to the number of megabytes or gigabytes in a DIMM: 32, 64, 128
megabytes, and so on, or 1 GB.
–Minimum memory capacity in the Octane workstation is 64 MB (2 x 32 MB
DIMM).
–Maximum memory capacity in the Octane workstation is 8 GB (8 x 1 GB
DIMM).

Removing DIMMs
Your upgrade kit includes two 1 GB DIMMs. Install these DIMMs ahead of any lower
density DIMMs, as explained in “About Memory”on page 6. If there are no 1 GB DIMMs
currently installed, remove the lower density DIMMs populating bank 1. If there are 1
GB DIMMs installed, remove any lower density DIMMs currently populating the next
bank. The following procedure assumes there are no 1 GB DIMMs currently installed.
Caution: Memory modules are extremely sensitive to static electricity. Handle the
modules carefully, and wear the wrist strap while removing them.
1. Locate the lower density DIMMs in bank 1.
Caution: Do not touch the connector near the DIMM removal lever.
2. Remove the DIMM from the first socket of bank 1, as shown in Figure 6.
•Press down on the latch at the end of the DIMM socket. The DIMM partially
ejects from the socket (A).

3. Remove the DIMM from the second socket of bank 1, following the procedure in
step 2.
Caution: Do not touch the connector near the DIMM removal levers.
You are now ready to begin the installation.
Installing 2 GB of Memory
This procedure assumes there are no 1 GB DIMMs currently installed, and you are
installing the two 1 GB upgrade DIMMs in bank 1, sockets 1 and 2.
Caution: Memory modules are extremely sensitive to static electricity. Handle the
modules carefully, and wear the wrist strap while installing them.
To install the two 1 GB upgrade DIMMs, read the “About Memory”section on page 6,
then follow these steps:
1. Insert a 1 GB upgrade DIMM into the first socket in bank 1 (gently but firmly).
DIMMs are notched on the bottom so they cannot be inserted incorrectly, as shown
in Figure 7.
You hear a click as it is seated, and the latch on the end of the socket moves up.
2. Insert the other 1 GB upgrade DIMM into the second socket in bank 1 (gently but
firmly).
3. You are finished installing 2 GB of memory.
If you want to reinstall the lower density DIMMs you removed, make sure you
follow the rules in the “About Memory”section on page 6. This means you may
need to remove any existing DIMMs (except for the 1 GB DIMMs), and reinstall
them in the proper order.

Replacing the System Module
1. Remove the caps on the compression connectors on the back of the system module.
Do not touch the system module compression connectors as you lift the module into
the workstation.
Caution: Do not insert the system module into the workstation unless the power
cord is unplugged from the electrical socket. Inserting the system module with the
power cord connected to the electrical socket causes damage to the workstation.
2. Grasp the system module by its immovable handle and support it with one hand as
you slide it into the chassis.
3. Push the module completely into the chassis using the immovable handle. (Both
sliding handles protrude.) The system module stops when it is slightly out of the
chassis.
4. Push the sliding handles simultaneously to connect the system module to the
workstation. Push firmly on the handles to completely lock the system module to
the workstation.
The sliding handles are completely recessed and the system module is flush with
the chassis when it is fully seated and locked to the workstation.
5. Tighten the captive screws in the sliding handles to attach the system module to the
chassis.
6. Remove the wrist strap.
7. Replace any cables you removed and plug in the power cord.
Powering On Your Workstation
1. Push the power button on your workstation, then press the power switch on your
monitor.
2. Replace the lockbar.
•Open the cover on the front of your workstation.

Silicon Graphics®OCTANE®R12000™2 GB Memory Upgrade Kit Installation Guide
Verifying Memory Installation
1. After you power on your system, choose Toolchest >System> System Manager >
Hardware and Devices > About This System, and check the amount of memory
displayed for Main Memory.
The displayed memory should equal the original amount of memory minus any
memory you removed, plus the 2 GB upgrade. For example, if you originally had
256 MB, removed two 32 MB DIMMs, then installed the two 1 GB DIMMs, the
System Manager should display 2.192 GB of memory.
2. If the amount of memory is incorrect, follow the directions in this flier to power off
your system, then check the installation or removal procedure.
•Check the angle of the DIMMs. They should be upright and completely seated.
•Recheck the installation procedure, then power on your workstation. If the
amount of memory displayed in About This System is still incorrect, refer to
Chapter 9, “Troubleshooting”in your Octane Workstation Owner’s Guide.
Troubleshooting
For an explanation of memory-related error codes and other troubleshooting
information, refer to Chapter 9, “Troubleshooting”in your Octane Workstation Owner’s
Guide.
