Chapter 4. Removing and replacing blade server components
Use this information to remove and replace components of the PS703 or PS704 blade server that are
replaceable.
Replaceable components are of three types:
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 blade server.
v Field replaceable unit (FRU): FRUs must be installed only by trained service technicians.
See Chapter 3, "Parts listing, type 7891," on page 225 to determine whether a part is a tier 1 CRU, tier 2
CRU, or FRU component.
For information about the terms of the warranty and getting service and assistance, see the Warranty and
Support Information document.
Installation guidelines
Follow these guidelines to remove and replace blade server components.
v Read the safety information in the Safety topic and the guidelines in "Handling static-sensitive
devices" on page 230. This information will help you work safely.
v When you install a new blade server, download and apply the most recent firmware updates.
Download and install updated device drivers and the blade server firmware. Go to the IBM Support
site to download the updates. Select your product, type, model, and operating system, and then click
Go. Click the Download tab, if necessary, for device driver and firmware updates.
Note: Changes are made periodically to the IBM website. Procedures for locating firmware and
documentation might vary slightly from what is described in this documentation.
v Observe good housekeeping in the area where you are working. Place removed covers and other parts
in a safe place.
v Back up all important data before you make changes to disk drives.
v Before you remove a hot-swap blade server from the BladeCenter unit, you must shut down the
operating system and turn off the blade server. You do not have to shut down the BladeCenter unit
itself.
v Blue on a component indicates touch points, where you can grip the component to remove it from or
install it in the blade server, open or close a latch, and so on.
v Orange on a component or an orange label on or near a component indicates that the component can
be hot-swapped, which means that if the blade server and operating system support hot-swap
capability, you can remove or install the component while the blade server is running. (Orange can also
indicate touch points on hot-swap components.) See the instructions for removing or installing a
specific hot-swap component for any additional procedures that you might have to perform before you
remove or install the component.
v When you are finished working on the blade server, reinstall all safety shields, guards, labels, and
ground wires.
See the ServerProven website for information about supported operating-system versions and all blade
server optional devices.
