Microprocessor installation - IBM eServer xSeries 350, Netfinity 6000R

Content

The server comes with one microprocessor installed on the system board. The server supports up to four microprocessors. If you install at least one additional microprocessor, the server can operate as a symmetric multiprocessing (SMP) server. With SMP, certain operating systems and application programs can distribute the processing load among the microprocessors.

Before you begin:

• 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 level of BIOS for the server.
• Click here to review a list of supported SMP operating systems.
  

WARNING: To avoid damage and ensure proper server operation when you install a new or an additional microprocessor, use microprocessors that have the same cache size and type, and the same clock speed. Microprocessor internal and external clock frequencies must be identical.

Notes:

1. To order additional microprocessor options, contact the IBM reseller or IBM marketing representative.
2. The server comes standard with one microprocessor installed in microprocessor connector J34 (slot 1) on the system board, and a terminator card in microprocessor slot 4. The microprocessor in slot 1 is the startup (boot) microprocessor. The microprocessor installed in microprocessor connector J35 is microprocessor 2 (slot 2); the microprocessor installed in microprocessor connector J36 is microprocessor 3 (slot 3); and the microprocessor installed in microprocessor connector J37 is microprocessor 4 (slot 4). If more than one microprocessor is installed, the highest numbered microprocessor is the microprocessor from which the server will start. The lower numbered microprocessors are used as application microprocessors.
   
3. If you replace the microprocessors in the server with microprocessors of a different speed, be sure to set the microprocessor core frequency selection jumper block correctly, as described in this section.
4. The server does not support replaceable voltage regulator modules (VRMs).

If you need to install additional microprocessors, install them in the following order:

1. Slot 1 (first slot, connector J34)
2. Slot 2 (second slot, connector J35)
3. Slot 3 (third slot, connector J36)
4. Slot 4 (fourth slot, connector J37)

Note: The server comes with a terminator card installed in microprocessor slot 4. To ensure proper server operation, the terminator card must remain installed in microprocessor slot 4 until you have installed microprocessors in slots 1 through 3.

The following illustration is a simplified layout of the microprocessor connector locations and other microprocessor related components on the system board.

Note: The illustrations in this document might differ slightly from the hardware.

2. Microprocessor slot 2 (J35)
3. Microprocessor slot 3 (J36)
4. Microprocessor slot 4 (J37)
5. Memory board (J40)

9. PCI slot 5, 64-bit 33 MHz (J54 - 5V) Bus C
10. PCI slot 6, 64-bit 33 MHz (J55 - 5V) Bus C
11. PCI hot-plug switch card (J1)
12. PCI slot 1, 32-bit 33 MHz (J50 - 5V) Bus A
13. Battery

The following illustration shows how to install a microprocessor on the system board.

Note: The illustrations in this document might differ slightly from the hardware.

Note: If you are replacing a failed microprocessor, verify that you have selected the correct microprocessor for replacement. To do this, check the Diagnostic panel that is located under the top cover to see which LED is on.

1. Turn off the server and disconnect all power cords and external cables; then, remove the top cover
2. Determine the slot where the microprocessor is to be installed.
3. If you have installed microprocessors in slots 1 through 3 and you are now installing a microprocessor in slot 4, remove the terminator card from the microprocessor connector. Store the terminator card in a safe place in the static-protective package that the new microprocessor comes in; you will need to install it again if you ever remove the microprocessor.
4. Install the microprocessor:
   1. Touch the static-protective package containing the new microprocessor to any unpainted metal surface on the server; then, remove the microprocessor from the package.
   2. Hold the microprocessor by the open latches, and center the microprocessor over the microprocessor connector.
      
      Note: Make sure that the microprocessor is oriented and aligned correctly before you try to close the latches.
      
      
   3. Carefully close the latches to seat the microprocessor in the connector.
      
      
5. If you replace the microprocessors in the server with microprocessors of a different speed, use the correct microprocessor core frequency settings. To ensure that the server maintains the correct microprocessor bus-to-core ratio, you must set the following microprocessor speed (core-frequency-selection) jumpers: J13, J27, J28, and J29. The jumpers on this block are in the following order, from top to bottom: J13, J27, J28, and J29.
   
   Correct Microprocessor-core-frequency settings
   

   J13	J27	J28	J29	Bus Ratio	Core Frequency (MHz)
   H	L	L	H	7:1	700/100
   H	L	L	H	8:1	800/100

   
   
6. Install any other options for the server.
