Expansion boards (on page 48)
o Processors (on page 36), except the processor installed in socket 1
IMPORTANT: Processor socket 1 and PPM slot 1 must be populated at all times or the server
does not function properly.
o PPMs ("PPM" on page 41), except the PPM installed in slot 1
o DIMMs (on page 42), except the first bank

2. Reseat the processor in socket 1.
3. Reseat the remaining processors, rebooting after each installation to identify any failed processors.
IMPORTANT: Populate the processors in the following order: 1, 2, 4, 3.
IMPORTANT: Always install a PPM when you install a processor. The system fails to boot if the
PPM is missing.
4. Replace the processor in socket 1.
5. Replace the processor board, if applicable.
6. Replace the system board.
IMPORTANT: If replacing the system board or clearing NVRAM, you must re-enter the server
serial number through RBSU ("Re-entering the server serial number and product ID" on page
58).
Memory-related port 85 codes
Memory-related port 85 codes display in the format 4xh.
IMPORTANT: Reboot the server after completing each numbered step. If the error condition
continues, proceed with the next step.
To troubleshoot memory-related error codes:
1. Check the memory LEDs ("Systems Insight Display LEDs" on page 78) for any identified errors or
failed DIMMs, and take corrective action.
2. Bring the server to base configuration by removing all components that are not required by the
server to complete POST. This process can include removing all:

o Processors (on page 36), except the processor installed in socket 1
IMPORTANT: Processor socket 1 and PPM slot 1 must be populated at all times or the server
does not function properly.
