Dell™ PowerEdge™ Systems — Microprocessor Upgrade Guide WARNING: The power supplies in a PowerEdge system may produce high voltages and energy hazards, which can cause bodily harm. Only trained service technicians are authorized to remove the computer cover and access any of the components inside the computer. For more information, see “Safety Instructions” in your system’s Installation and Troubleshooting Guide.
The contents of your kit will vary, depending on the PowerEdge system and the number of microprocessors you are installing. Each kit will have one or more new Pentium II or Pentium III microprocessor(s), diskettes containing the Resource Configuration Utility (RCU), BIOS, embedded server management (ESM) firmware, and diagnostics. Also included, for some system models, is a cooling shroud and mounting hardware or a replacement system board mounting plate or tray.
NOTICE: Do not attempt to operate a system with one Pentium II microprocessor and one Pentium III microprocessor. Damage to one or both of the microprocessors and/or the system board may occur. NOTICE: All empty microprocessor connectors must be populated with a terminator card. If your system supports more than one microprocessor and you are not installing the maximum number of microprocessors, the remaining microprocessor connectors must have a terminator card.
3. After the system completes the boot routine, follow the instructions on the screen. 4. After the message appears on the screen, remove the BIOS diskette from the diskette drive and follow the instructions on the screen to reboot the system. Saving RCU Configuration Settings Use the RCU to save the current system configuration settings by performing the following steps: 1. Insert the RCU diskette into the diskette drive and reboot the system. 2.
5. Install the upgrade microprocessor. See “Installing the Upgrade Microprocessors” found later in this document. 6. Replace the cooling shroud. See “Removing and Replacing the Cooling Shroud,” found later in this document. If the upgrade kit comes with a new cooling shroud, you must install the new cooling shroud. See “Installing a New Cooling Shroud,” found later in this document. 7. Reassemble and check the system, as follows: a.
Installing Upgrade Microprocessors in the PowerEdge 2300 To upgrade to Pentium II or Pentium III microprocessors in the PowerEdge 2300, perform the following steps. WARNING: The power supplies in this computer system produce high voltages and energy hazards, which can cause bodily harm. Only trained service technicians are authorized to remove the computer cover and access any of the components inside the computer.
e. Record the locations and disconnect all internal cables attached to the system board. f. At the left side of the system, locate and remove the three screws that secure the system board and mounting plate to the chassis (see Figure 1-1). mounting screws (3) system board and mountingplate assembly Figure 1-1. Removing the System Board Assembly 3. support.dell.com g. Slide the system board and mounting plate assembly forward about 12.7 millimeters (mm) (0.
4. Remove the microprocessor. See “Removing the Microprocessors,” found later in this document. 5. Remove the cooling shroud.

Replace the cooling shroud. See “Removing and Replacing the Cooling Shroud,” found later in this document.
CAUTION: When handling the SEC cartridge and heat sink assembly, take care to avoid sharp edges on the heat sink. NOTICE: See "Precautionary Measures," found earlier in this document for important information to prevent damage to the system from ESD. a. Remove the cooling shroud. See “Removing and Replacing the Cooling Shroud,” found later in this document. b. Pull the tab on one side of the guide bracket away from the end of the heat sink and pull up slightly on the cartridge. c.
3. Install the replacement SEC cartridge and heat sink assembly as follows: a. Remove the terminator card or old SEC cartridge from the guide bracket assembly. b. Slide the SEC cartridge into the guide bracket assembly, and firmly seat the assembly until the tabs on the guide bracket assembly snap into place over the ends of the heat sink (see Figure 1-3). thumbscrew retention pins (2) threaded stud Figure 1-3. Installing an SEC Cartridge and Heat Sink Assembly 4. Reassemble and check the system.
If you are upgrading a PowerEdge 4300 with a microprocessor with an operating frequency less than 600 MHz, you do not need to replace the system board mounting tray. 1. Remove the system board mounting tray as follows. WARNING: The power supplies in this computer system produce high voltages and energy hazards, which can cause bodily harm. Only trained service technicians are authorized to remove the computer cover and access any of the components inside the computer.
4. Replace the guide brackets. See “Removing and Replacing the Guide Brackets,” found later in this document. 5. Install the upgrade microprocessor. See “Installing the Upgrade Microprocessor,” found later in this document. 6. Reassemble and check the system. See “Reassembling and Checking the System,” found later in this document. system board tray tray latch Figure 1-4.

Removing the System Board Installing Upgrade Microprocessors in the PowerEdge 4350 To upgrade to Pentium II or Pentium III microprocessors in the PowerEdge 4350, perform the following steps: 1. Access the system board, which involves the following steps: a. Disconnecting power and peripheral cables. b. Removing the covers. c. Removing the front bezel. d. Removing the cooling fan shroud.
2. Remove the microprocessors. See “Removing the Microprocessors,” found later in this document. 3. Remove and replace the guide brackets.

Removing the Microprocessor Removing and Replacing the Guide Brackets To remove the guide bracket assembly, perform the following steps: 1. Remove any terminator card installed in the guide bracket. 2. Remove any microprocessor assembly installed in the guide bracket. 3. Use a #2 Phillips screwdriver to loosen the four captive nuts that secure the guide bracket assembly to the system board (see Figure 1-7). 4.

Removing and Replacing the Cooling Shroud The plastic cooling shroud inside the system is used to improve airflow over the microprocessors. You may need to remove this shroud to access certain components on the system board. Removing the Cooling Shroud To remove the cooling shroud, perform the following steps.
thumbscrew retention pins (2) Figure 1-9. Removing the Cooling Shroud Replacing the Cooling Shroud To replace the cooling shroud, perform the following steps: 1. Hook the upper edge of the large opening on the end of the cooling shroud over the top of the cooling fan on the system back panel. 2. Lower the other end of the shroud into place over the microprocessor(s). 3. Secure the shroud by reinstalling the two retention pins.
To install an upgrade microprocessor, perform the following steps: 1. Insert the new microprocessor into the system board connector (see Figure 1-10). 2. Press the microprocessor firmly into its connector until it is fully seated and the latches snap into place. You must use up to 25 lb of force to fully seat the microprocessor. For Pentium III microprocessors, you do not need to change the jumper settings on the system board.
Installing a New Cooling Shroud If a cooling shroud came with your microprocessor upgrade kit and your system is a PowerEdge 1300 or PowerEdge 2300, you must install the cooling shroud provided in the upgrade kit. To install a cooling shroud, perform the following steps: 1. Carefully position the shroud into place with the square opening over the bulkhead fan and the top of the shroud’s other end resting over the microprocessors, as shown in Figure 1-11. 2.
1. Close the computer panel doors (for PowerEdge 4350 systems only) or replace the covers and front bezel, and reconnect your computer and peripherals to their power sources and turn them on. As the system boots, it detects the presence of the new microprocessor and automatically changes the system configuration information in the System Setup program. The following message appears: 2.
