Abstract
This document contains a table entitled Netfinity 5500 M20 - Installing and upgrading the microprocessor
Content
The server comes with one microprocessor installed on the processor board. If you install additional microprocessors, the server can operate as a symmetric multiprocessing (SMP) server. With SMP, certain operating systems and application programs can distribute the processing load between the microprocessors. This enhances performance for database and point-of-sale applications, integrated manufacturing solutions, and other applications.
To avoid damage and ensure proper server operation when you install new or additional microprocessors, use microprocessors that have the same cache size and type, and the same clock speed. Microprocessor internal and external clock frequencies must be identical.
NOTE:
- Read Safety information in the HMM.
- Thoroughly review the documentation that comes with the microprocessor, so that you can determine whether you need to update the server BIOS to the latest level.
- Obtain an SMP-capable operating system (optional). For a list of supported operating systems, see http://www.ibm.com/servers/eserver/serverproven/compat/us/on the World Wide Web.
NOTE:
1. The following illustrations might differ slightly from the hardware.
2. If you replace the microprocessor in the server with a microprocessor that operates at a different speed, be sure to set the microprocessor core frequency selection jumpers correctly. See Processor board jumpers for more information.
3. The microprocessor that is installed in microprocessor connector J1 is CPU or microprocessor 1. If a microprocessor is installed in microprocessor connector J2, it is CPU or microprocessor 2; a microprocessor installed in J3 is CPU or microprocessor 3; a microprocessor installed in J4 is CPU or microprocessor 4. See Table 13 for information on the order in which microprocessors and voltage regulator modules (VRMs) must be installed. If the server has only one microprocessor installed, that microprocessor is installed in microprocessor connector J1 and is the startup (boot) processor. If more than one microprocessor is installed, the microprocessor installed in the highest numbered microprocessor connector (normally J4) is the startup processor and the microprocessor installed in J1 is the application processor.
4. VRM 2 is shared between microprocessor 1 and microprocessor 2. VRM 5 is shared between microprocessor 4 and microprocessor 6.
5. Terminator cards are installed with the arrow pointing towards the rear of the system.
The following table shows the order in which additional microprocessors and VRMs should be installed.

Refer to the following illustrations of the processor support tray and processor board while you perform the following steps.
NOTE: For simplicity, the illustrations show only the processor support tray and processor board; you do not need to remove the processor support tray and processor board to install a microprocessor.
1. Processor support tray cover
2. Quarter-turn fasteners
3. Latches
4. Second installed microprocessor (microprocessor 4)
5. First installed microprocessor (microprocessor 1)
6. Microprocessor connector 1 (J1)
7. Microprocessor connector 2 (J2)
8. Microprocessor connector 3 (J3)
9. Microprocessor connector 4 (J4)
10. Terminator card
11. VRM connectors 5 (J17) and 6 (J18)
12. VRMs for second microprocessor (VRMs 5 and 6)
13. VRMs for first microprocessor (VRMs 1 and 2)
To install an additional microprocessor
1. Turn off the server and peripheral devices and disconnect all external cables and power cords (see Preparing to install options in the HMM); then remove the top cover (see Top cover removal in the HMM).
2. Turn the two quarter-turn fasteners 2 on the processor support tray cover 1 one quarter turn and remove the cover from the processor support tray.
3. Determine the connectors where the microprocessor and VRMs are to be installed. See Table 13.
4. Remove the terminator card 10 from the microprocessor connector 9. Store the terminator card in a safe place in the static-protective package that the new microprocessor is shipped in; you will need to install it again if you ever remove the microprocessor.
5. Install the microprocessor:
a. Touch the static-protective package containing the new microprocessor to any unpainted metal surface on the server; then, remove the microprocessor from the package.
b. Hold the microprocessor 4 by the open latches 3, and center the microprocessor over the microprocessor connector 9.NOTE: Make sure the microprocessor is oriented and aligned correctly before you try to close the latches.
c. Carefully close the latches 3 to seat the microprocessor in the connector.
6. Install the voltage regulator modules (VRMs) 12 included in the microprocessor kit:
a. Remove fan assembly 4 to allow access to the VRM connectors. See Hot-swap fan assembly replacement in the HMM for instructions on removing fan assembly 4.
b. Determine the connectors where the VRMs are to be installed. See Table 13. The microprocessor upgrade kit comes with two VRMs. You might need to install only one, depending upon the number of microprocessors in the server.
c. Center the VRM 12 over the connector 11. Make sure that the VRM is oriented and aligned correctly; then, press the VRM into the connector.
d. Repeat the preceding step for the second VRM, if needed. If you need to install only one VRM, store the remaining VRM in a safe place to use as a replacement, if you ever need one.NOTE: If you remove the microprocessor at some time in the future, remember to install the terminator card in the appropriate microprocessor connector and to remove the VRMs for that microprocessor.
e. Install fan assembly 4. See Hot-swap fan assembly replacement in the HMM for instructions on installing fan assembly 4.
7. Install the processor support tray cover 1 and turn the two quarter-turn fasteners 2 one quarter turn to secure the cover.
8. If you have other options to install or remove, do so now; otherwise, go to Completing the installation in the HMM.
