Chapter 5. Removing and replacing server components
Replaceable components are of four types:
v Consumable Parts: Purchase and replacement of consumable parts
(components, such as batteries and printer cartridges, that have depletable life)
is your responsibility. If IBM acquires or installs a consumable part 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, Types 4255, 7945, and 7949 server,” on page 157 to
determine whether a component is a Tier 1 CRU, Tier 2 CRU, or FRU.
For information about the terms of the warranty and getting service and assistance,
see the Warranty Information document.
Installation guidelines
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
device.
Before you remove or replace a component, read the following information:
v Read the safety information that begins on page vii, the guidelines in “Working
inside the server with the power on” on page 171, and “Handling static-sensitive
devices” on page 171. 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.
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.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 x3650 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 xSeries Tools Center at
