Upgrading a processor

Hewlett Packard Enterprise recommends identifying the processor heatsink module components before performing this procedure. For more information, see Processor, heatsink, and socket components.

IMPORTANT:

Existing HPE ProLiant and HPE Synergy Gen10 server products containing first-generation Intel Xeon Scalable processors may not be upgraded to second-generation Intel Xeon Scalable processors at this time.

For more information, see the product QuickSpecs on the Hewlett Packard Enterprise website (https://www.hpe.com/info/qs).

Prerequisites

Before installing this option, be sure that you have the following items:

The components included with the hardware option kit
T-30 Torx screwdriver
T-10 Torx screwdriver

Procedure

Observe the following alerts:
CAUTION: When handling the heatsink, always hold it along the top and bottom of the fins. Holding it from the sides can damage the fins.

CAUTION: To avoid damage to the processor or system board, only authorized personnel should attempt to replace or install the processor in this server.

CAUTION: To prevent possible server malfunction and damage to the equipment, multiprocessor configurations must contain processors with the same part number.

CAUTION: If installing a processor with a faster speed, update the system ROM before installing the processor.
To download firmware and view installation instructions, see the Hewlett Packard Enterprise Support Center website.

CAUTION: THE CONTACTS ARE VERY FRAGILE AND EASILY DAMAGED. To avoid damage to the socket or processor, do not touch the contacts.
Power down the server.
Remove all power:
1. Disconnect each power cord from the power source.
2. Disconnect each power cord from the server.
Do one of the following:
- Extend the server from the rack (Extend the server from the rack).
- Remove the server from the rack (Removing the server from the rack).
Remove the access panel (Removing the access panel).

CAUTION: Do not operate the server for long periods with the access panel open or removed. Operating the server in this manner results in improper airflow and improper cooling that can lead to thermal damage.
If installed, do the following:
1. Remove the air baffle (Removing the air baffle).
2. Remove the processor mezzanine tray (Removing the processor mezzanine tray).
3. Remove the CPU Mezzanine UPI performance kit (Removing the CPU Mezzanine UPI performance kit).
  NOTE:
  Depending on the server configuration, your heatsink might appear different.
Identify the processor to remove.
Remove the processor heatsink assembly:
1. Allow the heatsink to cool.
2. Loosen the heatsink nuts in the order specified by the label on the heatsink.
3. Lift the processor heatsink assembly and move it away from the system board.
4. Turn the assembly over and place it on a work surface with the processor facing up.
5. Install the dust cover.
Release the thermal grease tension between the processor and heatsink:
1. Locate the tension release slot between the frame and heatsink.
  The slot is across from the Pin 1 indicator, near the corner.
2. Insert a 1/4 flathead screwdriver into the slot.
  Be sure that the screwdriver is between the frame and the heatsink.
3. To release the tension of the thermal grease, gently rotate the screwdriver.
4. Unlatch the remaining corners of the frame.
5. Separate the frame from the heatsink.
  The processor remains attached to the frame.
Using a cleaning solvent, remove the existing thermal grease from the processor and heatsink.
Apply thermal grease or a thermal pad to the new processor.
Install the processor on the heatsink:
1. Align the Pin 1 indicator on the frame to the Pin 1 indicator on the heatsink.
2. Latch the processor frame to the heatsink.
Install the processor heatsink assembly:
1. Remove the dust cover.
2. Locate the Pin 1 indicator on the processor frame and the socket.
3. Align the processor heatsink assembly with the alignment pins and gently lower it down until it sits evenly on the socket.
  The heatsink alignment pins are keyed. The processor will only install one way.
  A standard heatsink is shown. Your heatsink might look different.
4. Using a T-30 Torx screwdriver, tighten the nuts until they stop.
If removed, do the following:
1. Install the air baffle (Installing the air baffle).
2. Install the processor mezzanine tray (Installing a processor mezzanine tray).
3. Install the CPU Mezzanine UPI performance kit (Installing a CPU Mezzanine UPI performance kit).
Install the access panel (Installing the access panel).
Install the server into the rack (Installing the server into the rack).
Connect each power cord to the server.
Connect each power cord to the power source.
Power up the server.
