Chapter 4. Removing and replacing BladeCenter HT
components
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 can install a Tier 2 CRU yourself or
request IBM to install it, at no additional charge, under the type of warranty
service that is designed for your computer.
v
Field replaceable unit (FRU):
FRUs must be installed only by trained service
technicians.
See Chapter 3, “Parts listing,” on page 23 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 and Support Information
document.
Installation guidelines
Before you remove or replace a component, read the following information:
v
Read the safety information that begins on page vii and “Handling static-sensitive
devices” on page 32. This information will help you work safely.
v
Observe good housekeeping in the area where you are working. Place removed
covers and other parts in a safe place.
v
You do not have to disconnect the BladeCenter HT unit from power to install or
replace any of the hot-swap modules in the BladeCenter HT unit. You must shut
down the operating system and turn off a blade server before you remove the
blade server, but you do not have to remove power from the BladeCenter HT unit
itself.
v
Do not attempt to lift an object that you think is too heavy for you. If you have to
lift a heavy object, observe the following precautions:
– Make sure that you stand safely without slipping.
– Distribute the weight of the object equally between your feet.
– Use a slow lifting force. Never move suddenly or twist when you lift a heavy
object.
– To avoid straining the muscles in your back, lift by standing or by pushing up
with your leg muscles.
v
Make sure that you have an adequate number of properly grounded electrical
outlets for the BladeCenter HT unit.
v
Back up all important data before you make changes to disk drives.
v
Have a 3/16 in. flat-blade screwdriver available.
v
Have a phillips-head #1 screwdriver available.
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 you can remove or
install the component while the BladeCenter HT unit 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.
