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 IBM 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 IBM
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 IBM to install it, at no
additional charge, under the type of warranty service that is designated for your server.
See Chapter 4 “Parts listing, IBM NeXtScale nx360 M4 Compute Node Type 5455” on page 81 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 “Getting help and technical assistance” on
page dccvi.
Installation tools
The following tools are required to remove or replace parts on the IBM NeXtScale nx360 M4 Compute Node
• Phillips screwdriver
• T8 torx screwdriver (part number 00FK488, provided on the back of the chassis)
• Flat-blade screwdriver
Installing an optional device
Some compute node components are available as both optional devices and replaceable components. The
installation procedure is the same for the optional device and the replaceable component.
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 91.
This information will help you work safely.
• Make sure that the devices that you are installing are supported. For a list of supported optional devices
for the compute node, see http://www.ibm.com/systems/info/x86servers/serverproven/compat/us.
