Introduction

This guide demonstrates how to replace the Central Processing (Processor) Unit (CPU) on the ORV1 Leopard server.

    • Perform a warm shut down on the server. Run:

    • ssh -l root <hostname> shutdown -h now

    Edit

  2. Disconnect the 10G network interface cable. Pull the 10G network interface cable pull-tab. Pull the 10G network interface cable pull-tab.

    • Disconnect the 10G network interface cable.

    • Pull the 10G network interface cable pull-tab.

    Edit

  3. Pull the green retention plunger upwards. Pull the server away from the rack, as shown. Pull the server until about (2) inches of the black lid is exposed.

    • Pull the green retention plunger upwards.

    • Pull the server away from the rack, as shown.

    • Pull the server until about (2) inches of the black lid is exposed.

  5. Squeeze (2) lid retention handles towards the center of the node. Slide the lid towards the rear of the server node. Lift and remove the lid.

    • Squeeze (2) lid retention handles towards the center of the node.

    • Slide the lid towards the rear of the server node.

    • Lift and remove the lid.

    Edit

  6. Loosen (4) torque screws with a Phillips #2 screwdriver. Loosen screws in a diagonal sequence. Loosen each screw halfway first (about two driver rotations). Proceed loosening the screws completely.

    • Loosen (4) torque screws with a Phillips #2 screwdriver.

    • Loosen screws in a diagonal sequence.

    • Loosen each screw halfway first (about two driver rotations). Proceed loosening the screws completely.

    • Use your hand to apply pressure to the corner nearest the screw being loosened.

    Edit

  7. Lift the heatsink from the CPU socket. Place the heatsink to the side of the server chassis, near its respective CPU socket. Make sure the heatsink is facing upwards (with the thermal compound exposed).

    • Lift the heatsink from the CPU socket.

    • Place the heatsink to the side of the server chassis, near its respective CPU socket.

    • Make sure the heatsink is facing upwards (with the thermal compound exposed).

    Edit

  8. Scrape the thermal compound application from the heatsink using a plastic putty knife. Scrape the thermal compound parallel to the machined grain, as shown. Scrape the thermal compound parallel to the machined grain, as shown.

    • Scrape the thermal compound application from the heatsink using a plastic putty knife.

    • Scrape the thermal compound parallel to the machined grain, as shown.

    Edit

  9. Wipe the remaining thermal compound off of the heatsink with an ispropyl alcohol pad. Wipe the thermal compound parallel to the machined grain, as shown. Continue this process until no thermal compound residue remains on the heatsink.

    • Wipe the remaining thermal compound off of the heatsink with an ispropyl alcohol pad.

    • Wipe the thermal compound parallel to the machined grain, as shown.

    • Continue this process until no thermal compound residue remains on the heatsink.

    Edit

  10. Unlatch (2) CPU retention release levers Unlatch the 'unlock' retention lock first. Unlatch the 'lock' retention lock second.

    • Unlatch (2) CPU retention release levers

    • Unlatch the 'unlock' retention lock first.

    • Unlatch the 'lock' retention lock second.

    • Press the retention rods down and push them towards the CPU. Allow the retention rods to slowly lift.

    • CPU retention release levers are spring loaded. Apply slight pressure as they lift to avoid injury and damage.

    Edit

  11. Lift the CPU retention bracket.

    • Lift the CPU retention bracket.

    • Allow the CPU retention bracket to pivot, and let stand vertically.

    Edit

  12. Grasp the CPU by its sides.

    • Grasp the CPU by its sides.

    • Lift the CPU from its socket.

    Edit

  13. Wipe the top of the CPU with an ispropyl alcohol pad to remove the thermal compound residue. Multiple passes may be needed. Continue until all the thermal compound residue has been removed. Multiple passes may be needed. Continue until all the thermal compound residue has been removed.

    • Wipe the top of the CPU with an ispropyl alcohol pad to remove the thermal compound residue.

    • Multiple passes may be needed. Continue until all the thermal compound residue has been removed.

    Edit

  14. Orientate the CPU so that the arrow printed on the CPU aligns with the arrow printed on the CPU retention housing, as shown. Orientate the CPU so that the arrow printed on the CPU aligns with the arrow printed on the CPU retention housing, as shown.

    • Orientate the CPU so that the arrow printed on the CPU aligns with the arrow printed on the CPU retention housing, as shown.

    Edit

  15. Lower the CPU directly onto its socket, as shown. Lower the CPU directly onto its socket, as shown.

    • Lower the CPU directly onto its socket, as shown.

    Edit

  16. Close the CPU retention gate. Ensure the 'lock' CPU retention lever is on top of the CPU retention gate lip, as shown.

    • Close the CPU retention gate.

    • Ensure the 'lock' CPU retention lever is on top of the CPU retention gate lip, as shown.

    Edit

  17. Lock the CPU in its socket. Close both retention levers. Close the 'lock retention lever first, and then the 'unlock' retention lever.

    • Lock the CPU in its socket.

    • Close both retention levers. Close the 'lock retention lever first, and then the 'unlock' retention lever.

    Edit

  18. Apply thermal compound to the top of the CPU using the 5-dot method. Place 0.2 grams of thermal compound on each CPU corner. Drag residue towards the center of the CPU. Place 0.2 grams of thermal compound on the center of the CPU.

    • Apply thermal compound to the top of the CPU using the 5-dot method.

    • Place 0.2 grams of thermal compound on each CPU corner. Drag residue towards the center of the CPU.
