Microprocessors - Netfinity 3500 - Type 8644

Microprocessors - Netfinity 3500 - Type 8644

The server comes with an Intel® Pentium® II microprocessor.
This microprocessor incorporates MMX™ technology with built-in ECC L2 cache.

If you do upgrade the microprocessor, use the instructions that come with the upgrade along with the instructions in 'Installing or Replacing Microprocessors'.

When you install an additional microprocessor, the Netfinity 3500 server can operate as a symmetric multiprocessing (SMP) server. With SMP, certain operating systems and application programs can distribute the processing load between microprocessors.. This can enhance performance for database and point-of-sale applications, integrated manufacturing solutions, and other applications.

The voltage regulator function is built into the system board. This feature supports each microprocessor on the system board. If you install a second microprocessor, it must operate at the same voltage as the primary microprocessor to ensure proper operation of the voltage regulator feature.

Installing or Replacing Microprocessors:

Use the following procedure for installing microprocessors. If you want to remove a microprocessor, reverse the order of the following steps.

Review the documentation that comes with the microprocessor, so that you can determine whether you need to update the server BIOS. ServerGuide includes IBM Update Connector, a dial-up program that keeps the BIOS and device drivers current. You can also obtain the latest level of BIOS for the server through the World Wide Web and the IBM PC Company Bulletin Board System (BBS).
Obtain an SMP operating system (optional). For a list of supported operating systems, see
http://www.pc.ibm.com/us/server
on the World Wide Web.
If you install an additional microprocessor that is different from the current installed microprocessor, the server operation might be unreliable.
To prevent this, use a microprocessor with the same internal and external clock speed, and the same cache size and voltage requirements as those of the currently installed microprocessor.
Microprocessor internal and external clock frequencies and cache size must be identical.
If you select a setting for the frequency jumper that is greater than the actual frequency of the microprocessor, you might damage the microprocessor.

If the server has been operating, the heat sinks on the installed microprocessor will be hot.

You can avoid getting a burn while removing an existing microprocessor or installing an additional one, if you let the components cool for 10 minutes before continuing with the procedures described in this section.

NOTE:

The microprocessor in the server comes with an attached heat sink. The microprocessor plugs into the primary microprocessor socket on the system board and is stabilized with a plastic bracket attached to the system board.
The type of heat sink in the server might be different from the heat sink shown in this procedure.
When you add a second microprocessor, it must operate at the same speed as the primary microprocessor. For information about the appropriate switch settings, see 'Microprocessor Speed Switches', or see the label inside the server cover.

To install a microprocessor

Remove the server cover
If the server does not come with an air baffle, go to Step 3.
If the server comes with an air baffle, remove the air baffle:
1. If the cables are in the way, move them.
2. Locate the three small levers on the air baffle that protrude through the holes on the rear of the server.
3. Press the levers down, toward the bottom, until they unlock.
4. Slide the air baffle away from the rear of the server.
5. Tilt the air baffle toward the microprocessors, and slide it out, under the metal bar and away from the two microprocessor/heat-sink assemblies.
6. Remove the air baffle from the server, and save it for later use.
If you are installing a second microprocessor in the server, go to Step 5.
If you are replacing an existing microprocessor, go to Step 4.
Remove the microprocessor:
1. Locate the appropriate microprocessor socket (primary or secondary) on the 'System Board'
2. Place your index fingers on the small retainer tabs on the top of the microprocessor. Push in toward the microprocessor until the tabs release.
3. Carefully place one hand on the server frame and pull the microprocessor up and out of the connector with the other hand.
4. Store the old microprocessor in a static-protective package.
5. Go to Step 7 to install the replacement microprocessor.
Locate the secondary microprocessor socket on the system board.
Remove the terminator card from the secondary microprocessor socket.
Touch the static-protective package containing the new microprocessor to any unpainted metal surface in the server, then, remove the new microprocessor.
Press in on the retainer tabs until they click.
NOTE: For the location of the (microprocessor) retainer tab, see Pentium® II
Align the new microprocessor with the appropriate connector (primary or secondary) on the system board and slide it into the guides. Press the microprocessor down until it snaps into place and is fully seated in the connector.
Pull outward on the (microprocessor) retainer tabs.
If the server comes with an air baffle, reinstall it.
To reinstall the air baffle, follow the instructions in Step 2 in reverse order.
If you replace the microprocessor with one that has a different speed, you must change the switch settings on the system board.
Since you installed a new microprocessor in the server, you must reconfigure the server.
Follow the procedure described in 'Configuration/Setup Utility Program Menus'.
You might also need to make changes to the operating system.
- If the opreating system does not support SMP, install one of the SMP operating systems that the server supports.
  See http://www.pc.ibm.com/us/server
  on the World Wide Web.
- If the operating system does support SMP, refer to the operating-system documentation.
  You might need to make changes so that the operaing system recognizes the new microprocessor.
If you want to install or remove any other options, do so now.
