Prepare the server for service.
- Power off the server
and disconnect the power cords from the power supplies.
See Powering Down the Server.
- Extend the server to the maintenance
See Extend the Server to the Maintenance Position.
- Attach an antistatic wrist strap
to your wrist, and then to a metal area on the chassis.
See Take Antistatic Measures.
- Remove the server top cover.
Remove the Server Top Cover.
If the server has a DVD drive, disconnect the DVD cable from the disk
backplane, carefully pull it through the chassis mid-wall, and move it to
the side away from of the air baffle.
For instructions for disconnecting the DVD cable from the disk backplane,
see Servicing the Power, FIM, Disk Backplane Data, and DVD Cables.
If the server has an Oracle PCIe NVMe switch card installed, disconnect
the switch card cables from the disk backplane, carefully pull them through
the chassis mid-wall, and move them to side away from the air baffle.
For instructions for disconnecting the switch card cables from the disk
backplane, see Servicing the NVMe Cables.
Lift the air baffle up and out of the server and put it aside.
- Identify the
location of the failed processor by pressing the Fault Remind
button on the motherboard.
Note - When the Fault Remind button is pressed, a LED located
next to the Fault Remind button lights green to indicate that there
is sufficient voltage present in the fault remind circuit to light
any fault LEDs that were lit due to a failure. If this LED fails
to light when you press the Fault Remind button, it is likely that
the capacitor powering the fault remind circuit has lost its charge.
This can happen if the Fault Remind button is pressed for a long
time with fault LEDs lit or if power has been removed from the server
for more than 15 minutes.
The processor fault LEDs are located next to the processor(s).
If the processor fault
LED is off, then the processor is operating properly.
If the processor fault LED is on (amber), then the processor is failed and should be
Processor 0 (P0) fault LED
Processor 1 (P1) fault LED
- Gently press down on the top of the heatsink to counteract the pressure of the captive
spring-loaded screws that secure the heatsink to the motherboard and loosen
the four Phillips captive screws in the heatsink for the failed processor
Using a No. 2 Phillips screwdriver, turn the screws counterclockwise
alternately one and one half turns until they are fully removed.
- To separate the heatsink from
the top of the processor, gently twist the heatsink left and right,
while pulling upward, and then lift off the heatsink and place it upside
down on a flat surface .
A thin layer of thermal grease separates the heatsink and
the processor. This grease acts as an adhesive.
Note - Do not allow the thermal grease to contaminate the work
space or other components.
- Use an alcohol pad to clean the
thermal grease from the underside of the heatsink.
Be very careful not to get the thermal grease on your fingers.
Failure to clean the heatsink prior to removing the processor could
result in the accidental contamination of the processor socket or other
components. Also, be careful not to get the grease on your fingers as
this could result in contamination of components.
- Disengage the processor
release lever on the
right side of the processor socket (viewing the server from the
front) by pushing down on the lever and moving it to the side away
from the processor, and then rotating the lever upward .
- Disengage the processor release
lever on the left side of the processor socket (viewing the server
from the front) by pushing down on the lever and moving it to the
side away from the processor, and then rotating the lever upward
- To lift the ILM assembly load plate off of the processor socket, rotate the processor release
lever on the right side of the processor toward the closed position (the ILM
assembly load plate is lifted up as the release lever is lowered toward the
closed position) and carefully swing the ILM load plate to the fully open
Caution - Whenever you remove
a processor, you should replace it with another processor and reinstall
the processor heatsink; otherwise, the server might overheat due
to improper airflow. For instructions for installing a processor,
see Install a Processor.
- To remove the processor from the processor socket, acquire the processor removal and
replacement tool and perform the following steps:
- Locate the button in the center of the top of the processor removal and replacement tool and
press it to the down position .
- Properly position the tool over
the processor socket and lower it into place over the processor
To properly position the tool over the processor socket, rotate
the tool until the green triangle on the side of the tool is facing
the front of the server and it is over the left side of the processor
socket when viewing the server from the front.
- Press the release lever on the
tool to release the center button and engage the processor .
An audible click indicates that the processor is engaged.
- Grasp the tool by the sides and
remove it from the server .
- Turn the tool upside down and
verify that it contains the processor .
- While holding the processor tool
up side down, press the center button on the tool to release the
- Carefully grasp the processor
by the front and back edges, lift it out of the tool and place it
with the circuit side down (the installed orientation) into an antistatic
- Carefully clean the thermal grease
off the top of the processor.
