Server Upgrade Process - Oracle SPARC T8-4 Service Manual

Server Upgrade Process

Server Upgrade Process
The SPARC T8-4 server supports two processor module configurations:
Fully-populated — Two processor modules
■
Half-populated— One processor module and one processor filler module
■
Processor modules are cold-service components that can be replaced only by qualified
service personnel. For the location of the processor modules, see
Components" on page
Caution -
electrostatic discharge. This discharge can cause failure of server components.
This table contains the steps for upgrading the server to a fully-populated configuration.
Step Description
1. Remove the upgrade components from their packaging, and
place them on an antistatic mat.
2. Remove the covers from the new processor module.
3. Verify that you have the correct DIMMs for your server. All of
the DIMMs must be either 32 or 64 GB, and they must match
the size and capacity of the DIMMs already installed in the
cpu node.
4. Install the DIMMs.
5. Check the server for faults. If any fault is present, you must
correct the fault and clear it from the server before you can
continue with the upgrade.
6. Shut down the server.
7. Remove the processor filler module from Slot 1.
8. Install the new processor module in Slot 1.
9. Return the server to operation.
10. Verify the installation. If any fault is present, you must correct
the fault and clear it from the server.
11. Review the root complex changes.
12. Review the PCIe card load balancing changes. Even though
the load balancing guidelines change with the u;pgrade, you
do not need to move any existing PCIe cards.
