Microprocessor kit - Netfinity 5500

Resolving The Problem

Your server comes with one microprocessor installed on the processor board. When you install an additional microprocessor kit, your 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.

Before you begin:
- 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 basic input/output system (BIOS). Click here to download the latest BIOS update.
- 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

NOTES
1. The illustrations in this section might differ slightly from your hardware.
2. To avoid damage and ensure proper server operation when you install a new or additional microprocessor, use the same speed and voltage as those of the currently installed microprocessor. Microprocessor internal and external clock frequencies must be identical.
3. The microprocessor that is installed in the primary microprocessor connector is CPU or processor 1. If a microprocessor is installed in the secondary microprocessor connector, it is CPU or processor 2. If the server has only one microprocessor installed, that microprocessor is installed in the primary microprocessor connector and is the boot processor. If the server has two microprocessors installed, the microprocessor in the secondary microprocessor connector is the boot processor and the microprocessor in the primary microprocessor connector is the application processor.

Refer to the following illustration while you perform the steps in this section.

NOTE
The illustration shows only the processor board for simplicity; you do not need to remove the processor board to install a microprocessor kit.

To install an additional microprocessor kit

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. Remove the terminator card 5 from the secondary microprocessor connector 4. You do not need the terminator card when you have a second microprocessor installed. You can store it in a safe place in the static-protective package that your new microprocessor is shipped in.

3. 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. Center the microprocessor 6 over the secondary connector 4.

c. Press in on the latches 7 and carefully insert the microprocessor into the connector.
d. Press outward on the latches 7 to lock the microprocessor in place.

4. Install the voltage regulator module (VRM) 1 included in the microprocessor kit in the secondary VRM connector 8.
