Netfinity 3500 - Microprocessors

Applicable to: World-Wide

Microprocessors
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.

Notes 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 on page 98, or see the label inside the server cover. To locate the microprocessor switch area of the system board, find the configuration switches section of the system-board illustration. See System Board on page 95.

To install a microprocessor:
1. Remove the server cover (see Side Access Cover on page 93).
2. If the server does not come with an air baffle, go to step 3 on page 86.
If the server comes with an air baffle, remove the air baffle:
a. If cables are in the way, move them.
b. Locate the three small levers on the air baffle that protrude through the holes on the rear of the server.

c. Press the levers down, toward the bottom, until they unlock.
d. Slide the air baffle away from the rear of the server.
e. Tilt the air baffle toward the microprocessors, and slide it out, under the metal bar and away from the two microprocessor/heat-sink assemblies.
f. Remove the air baffle from the server, and save it for later use.
3. If you are installing a second microprocessor in the server, go to step 5 on page 87.
If you are replacing an existing microprocessor, go to step 4.
4. Remove the microprocessor:
a. Locate the appropriate microprocessor socket (primary or secondary) on the system board. (See the illustration in System Board )
b. Place your index fingers on the small retainer tabs on the top of the microprocessor. Push in toward the microprocessor until the tabs release.

c. Carefully place one hand on the server frame and pull the microprocessor up and out of the connector with the other hand.

d. Store the old microprocessor in a static-protective package.
e. Go to step 7 to install the replacement microprocessor.
5. Locate the secondary microprocessor socket on the system board. (See the illustration in "System Board")
6. Remove the terminator card in the secondary microprocessor socket.
7. Touch the static-protective package containing the new microprocessor to any unpainted metal surface in the server; then, remove the new microprocessor.
8. Press in on the retainer tabs until they click.

Note For the location of the retainer tabs, see the illustration in step 4b.

9. 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.
10. Pull outward on the retainer tabs.

11. If the server comes with an air baffle, reinstall it. To reinstall the air baffle, follow the instructions in step 2 in reverse order.

12. If you replace the microprocessor with one that has a different speed, you must change the switch settings on the system board. To locate the switches, see "System Board". For information about the appropriate switch settings, see "Microprocessor Speed Switches", or see the label inside the server cover.

13. 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 operating 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 operating system recognizes the new microprocessor.

14. If you want to install or remove any other options, do so now. Otherwise, go to "Completing the Installation".
