Central Processing Unit (CPU) Replacement

Disconnect the 10G cable NIC.

Pull the green retention plunger upwards and twist 90 degrees to lock in the upright position.

Using the handle located at the left side of the server sled, pull the sled outwards.

Remove the server sled and place it onto a crash cart or work bench for service.

Grab the center portion of the chassis lid as shown.

Firmly pull towards the front of the server chassis to release the lid.

Lift the lid and remove

DIMM slots and CPU locations are as shown.

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.

Lift the heatsink from the CPU socket.

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

Enure the heatsink is facing downwards (with the thermal compound exposed).

Unlatch the 'unlock' retention lock first, by simultaneously pushing down and inward on the lever as shown.

Unlatch the 'lock' retention lock second, by simultaneously pushing down and inward on the lever as shown.

Fully extend the second 'lock' lever.

Press the first 'unlock' retention lever down towards the CPU to allow the CPU retention bracket to lift.

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

Grasp the CPU by its sides and remove.

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.

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

Lower the CPU directly onto its socket, as shown.

Close the CPU retention gate.

Ensure the 'lock' CPU retention lever is on top of the CPU retention gate lip.

Close both retention levers.

Close the 'lock retention lever first, then the 'unlock' retention lever.

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.

0.2 grams is 'about' 1 hash mark tick on the 1 gram CPU thermal compound syringe.

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

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

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.

Lower the heatsink onto the CPU.

Ensure the heatsink screw posts are aligned with the CPU retention post holes.

Tighten screws in a diagonal sequence.

Tighten each screw halfway first.(about two driver rotations). Then, proceed to tighten each screw completely.

Insert the lid onto the server chassis.

Slide it towards the rear of the chassis until it clicks into place and resistance is felt.

Insert the server sled into the rack as shown.

If the green retention plunger is still in the upright position, twist it 90 degrees to release it. This will secure the server.

Press the power button to power-on the server.
