Chapter 5. Removing and replacing server 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,
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 (CRU):
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 ThinkServer sd350 Server Type 5493, Lenovo ThinkServer n400
Enclosure Type 5495” on page 67 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 C “Getting help and technical
assistance” on page 171.
Installing an optional device
Some compute node components are available as both an optional device and a replaceable component.
The installation procedure is the same for the optional device and the replaceable component.
Installation guidelines
Before you remove or replace a replaceable component or install an optional device, read the following
information:
• Before you begin, read “Safety” on page v and “Handling static-sensitive devices” on page 76. This
information will help you work safely.
• When you install your new compute node, 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
compute node is ready to function at maximum levels of performance.To download the latest firmware
and device drivers, go to http://www.lenovo.com/support and select
ThinkServer sd350 Server.
• Observe good housekeeping in the area where you are working. Place removed covers and other parts
in a safe place.
• Back up all important data before you make changes to hard disk drives.
• Before you remove a compute node from the Lenovo ThinkServer n400 Enclosure Type 5495 chassis,
you must shut down the operating system and turn off the compute node. You do not have to shut
down the chassis itself.
• Blue on a component indicates touch points, where you can grip the component to remove it from or
install it in the compute node, open or close a latch, and so on.
• For a list of supported optional devices for the compute node, see http://www.lenovo.com/us/en/
