Chapter 5. Removing and replacing components
Use this information to remove and replace the server components.
The types of replaceable components are:
• Structural parts: Purchase and replacement of structural parts (components, such as chassis assembly,
top cover, and bezel) is your responsibility. If Lenovo acquires or installs a structural component at
your request, you will be charged for the service.
• Tier 1 customer replaceable unit (CRU): Replacement of Tier 1 CRUs is your responsibility. If Lenovo
installs a Tier 1 CRU at your request, you will be charged for the installation.
• Tier 2 customer replaceable unit: You may install a Tier 2 CRU yourself or request Lenovo to install it, at
no additional charge, under the type of warranty service that is designated for your server.
See Chapter 4 “Parts listing, Lenovo NeXtScale nx360 M5 compute node” on page 85 to determine whether
a component is a structural part, Tier 1 CRU, or Tier 2 CRU.
For information about the terms of the warranty, see the Warranty Information document that comes with
the server.
For more information about getting service and assistance, see Appendix D “Getting help and technical
assistance” on page 985.

Installation guidelines
Use this information for installation.
Attention: Static electricity that is released to internal compute node components when the compute node
is powered-on might cause the system to halt, which might result in the loss of data. To avoid this potential
problem, always use an electrostatic-discharge wrist strap or other grounding system when removing or
installing a hot-swap device.
Before you install optional devices, read the following information:
• Read the safety information in “Safety” on page v and “Handling static-sensitive devices” on page
