Preparing The Server For Diagnosis; Minimum Hardware Configuration; Breaking Down The Server To Minimum Hardware Configuration; Dimm Population Information - HPE ProLiant MicroServer Gen10 Series Troubleshooting Manual

Preparing the server for diagnosis

Prerequisites
• Verify that the appropriate software is installed on the server.
• Hewlett Packard Enterprise recommends that you access the server documentation in the Hewlett
Packard Enterprise Information Library.
Procedure
1. Verify that the server is in the proper operating environment with adequate power, air conditioning, and
humidity control.
For the required environmental conditions, see the server user guide in the Hewlett Packard Enterprise
Information Library.
2. Record all error messages displayed by the system.
3. Remove all CD-ROMs, DVD-ROMs, USB drive keys, or SD cards that are not bootable devices.

Minimum hardware configuration

During the troubleshooting process, you might be asked to reduce the server to its minimum hardware
configuration. This configuration consists of only the components required to boot the server and successfully
pass POST.
When reducing the server to its minimum hardware configuration, keep in mind the following:
• Before removing any components, determine the minimum configuration for each component and follow all
guidelines in the server user guide.
• The processor is embedded into the system board. If an issue occurs with the processor, replace the
system board.

Breaking down the server to minimum hardware configuration

Procedure
1. Determine the minimum configuration for each component.
2. If installed, uninstall the following components based on the removal guidelines described in the server
maintenance and service guide, which can be found in the Hewlett Packard Enterprise Information
Library.
• Additional DIMMs
Leave only the minimum number of DIMMs required to boot the server. For more information, see the
memory guidelines in the Gen10 memory user guide.
• Hard drives and solid-state drives
• Optical drives (DVD-ROM, CD-ROM, and so forth)
• Expansion boards

DIMM population information

For specific DIMM population information, use the HPE Server Memory Configurator tool (https://
