Chapter 5. Removing and replacing server components
Replaceable components are of four types:
v Consumables: Purchase and replacement of consumables (components, such
as batteries and printer cartridges, that have depleting life) is your responsibility.
If IBM acquires or installs a consumable component at your request, you will be
charged for the service.
v 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.
v 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.
v Field replaceable unit (FRU): FRUs must be installed only by Trained service
technicians.
See Chapter 4, “Parts listing, System x3550 M3 Types 4254 and 7944,” on page
159 to determine whether a component is a Tier 1 CRU, Tier 2 CRU, or FRU.
For information about the terms of the warranty, see the Warranty Information
document that comes with the server.
Installation guidelines
Before you remove or replace a component, read the following information:
v Read the safety information that begins on page vii and the guidelines in
“Working inside the server with the power on” on page 169 and “Handling
static-sensitive devices” on page 169. This information will help you work safely.
v 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, complete the
following steps:
1. Go to http://www.ibm.com/systems/support/.
2. Under Product support, click System x.
3. Under Popular links, click Software and device drivers.
4. Click System x3550 M3 to display the matrix of downloadable files for the
server.
For additional information about tools for updating, managing, and deploying
firmware, see the System x and BladeCenter Tools Center at
http://publib.boulder.ibm.com/infocenter/toolsctr/v1r0/index.jsp.
v Before you install optional devices, make sure that the server is working
correctly. Start the server, and make sure that the operating system starts, if an
operating system is installed, or that a 19990305 error code is displayed,
indicating that an operating system was not found but the server is otherwise
working correctly. If the server is not working correctly, see Chapter 1, “Start
here,” on page 1 and Chapter 3, “Diagnostics,” on page 23 for diagnostic
information.
v Observe good housekeeping in the area where you are working. Place removed
covers and other parts in a safe place.
