Introduction

Overview

This guide demonstrates how to replace a central processing unit (CPU) in an Open Compute V2 server. == Acronyms and Terms == * CPU - Central Processing Unit * DIMM - Dual In-line Memory Module

  1. Identify the DIMM and CPU from the image shown.

    • Identify the DIMM and CPU from the image shown.

    • Use the image to correlate DIMM and CPU sockets with the case ticket.

  2. Remove the lid from the server node. Engage the lid with both hands, as shown. Push the lid towards the rear of the server.

    • Remove the lid from the server node.

    • Engage the lid with both hands, as shown.

    • Push the lid towards the rear of the server.

    • Lift the lid.

    Edit

  3. Loosen four Phillips #2 screws. Lightly press the heatsink downwards next to the screw being loosened. Loosen screws in a diagonal order.

    • Loosen four Phillips #2 screws.

    • Lightly press the heatsink downwards next to the screw being loosened.

    • Loosen screws in a diagonal order.

  4. Lift and remove the heatsink.

    • Lift and remove the heatsink.

  5. Press the CPU retention bracket lever (nearest the unlock symbol) down and away from the CPU. The retention lever is spring loaded. Apply force to the lever as it rises. The retention lever is spring loaded. Apply force to the lever as it rises.

    • Press the CPU retention bracket lever (nearest the unlock symbol) down and away from the CPU.

    • The retention lever is spring loaded. Apply force to the lever as it rises.

    Edit

  6. Repeat the process for the second CPU retention bracket lever.

    • Repeat the process for the second CPU retention bracket lever.

    Edit

  7. Pivot the gate so that the CPU can be removed. Lift the CPU away from its socket. Take care not to touch the LGA socket pins as you lift the CPU.

    • Pivot the gate so that the CPU can be removed.

    • Lift the CPU away from its socket.

    • Take care not to touch the LGA socket pins as you lift the CPU.

    Edit

  8. Align the arrow printed on the CPU with the arrow on the CPU retention bracket.

    • Align the arrow printed on the CPU with the arrow on the CPU retention bracket.

    • Seat the CPU in the socket.

    • Be careful when lowering the CPU into the socket. Mishandling the CPU can bend the LGA socket pins.

    Edit

  9. Lower the CPU retention gate. Lower and lock the CPU retention levers, as shown. Begin with the 'unlocked' lever symbol, then proceed to the 'locked' symbol retention lever.

    • Lower the CPU retention gate.

    • Lower and lock the CPU retention levers, as shown.

    • Begin with the 'unlocked' lever symbol, then proceed to the 'locked' symbol retention lever.

    Edit

  10. Apply thermal compound to the CPU, as shown. About 1 gram of thermal compound should be distributed evenly in five dots. Align two heatsink posts with two holes in the CPU housing bracket, as annotated.

    • Apply thermal compound to the CPU, as shown.

    • About 1 gram of thermal compound should be distributed evenly in five dots.

    • Align two heatsink posts with two holes in the CPU housing bracket, as annotated.

    • Pivot the heatsink so that all four screws are seated in the CPU housing bracket holes.

    • Tighten the four screws on the heatsink.

    Edit

  11. Install the lid back on the server. Install the lid back on the server. Install the lid back on the server.

    • Install the lid back on the server.
