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 “Front Panel
Components” on page 14 .
Caution -
These service procedures require that you handle components that are sensitive to
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 Link
1. Remove the upgrade components from their packaging, and
place them on an antistatic mat.
2. Remove the covers from the new processor module. “Remove a Processor Module or Processor Filler
Module” on page 60
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.
“Understanding DIMM Configurations” on page 69
4. Install the DIMMs. “Install a DIMM” on page 81
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.
“Check for Faults” on page 33
6. Shut down the server. “Removing Power From the Server” on page 50
7. Remove the processor filler module from Slot 1. “Remove a Processor Module or Processor Filler
Module” on page 60
8. Install the new processor module in Slot 1. “Install a Processor Module or Processor Filler
Module” on page 63
9. Return the server to operation. “Returning the Server to Operation” on page 191
10. Verify the installation. If any fault is present, you must correct
the fault and clear it from the server.
“Verify a Processor Module” on page 67
11. Review the root complex changes. “Understanding PCIe Root Complex
Connections” on page 155
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.
