Chapter 6. Removing And Replacing Components; Installation Guidelines - Lenovo x3300 M4 7382 Installation And Service Manual

Chapter 6. Removing and replacing components

There are three types of replaceable components.
• 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 5 "Parts listing, Lenovo System x3300 M4 Type 7382" on page 159 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 793.

Installation guidelines

Use the installation guidelines to install the System x3300 M4 Type 7382.
Attention: Static electricity that is released to internal server components when the server 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

sensitive devices" on page 171. 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 server, see

• When you install your new server, take the opportunity to download and apply the most recent firmware
updates. This step will help to ensure that any known issues are addressed and that your server is ready
to function at maximum levels of performance. To download firmware updates for your server, go to
www.ibm.com/support/ fixcentral
Important: Some cluster solutions require specific code levels or coordinated code updates. If the device
is part of a cluster solution, verify that the latest level of code is supported for the cluster solution before
you update the code.
