Chapter 5. Customer replacement units This chapter provides instructions for adding certain components to the blade server. Some removal instructions are provided in case you need to remove one option to install another. Installation guidelines Before you begin to install options in the blade server, read the following information: v Read Appendix B, "Safety information," on page 97 and the guidelines in "Handling static-sensitive devices." This information will help you work safely with the blade server and options. v Back up all important data before you make changes to disk drives. v For a list of supported options for the blade server, go to http://www.ibm.com/pc/ us/compat/. 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 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. System reliability considerations To help ensure proper cooling and system reliability, make sure that microprocessor socket 2 always contains either the microprocessor heat sink filler or a microprocessor and heat sink. Handling static-sensitive devices Attention: Static electricity can damage electronic devices and the system. To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them. To reduce the possibility of damage from electrostatic discharge, observe the following precautions: v Limit your movement. Movement can cause static electricity to build up around you. v Handle the device carefully, holding it by its edges or its frame. v Do not touch solder joints, pins, or exposed printed circuitry. v Do not leave the device where others can handle and possibly damage the device. v While the device is still in its static-protective package, touch it to an unpainted metal part of the BladeCenter unit or any unpainted metal surface on any other © Copyright IBM Corp. 2003 27

Chapter 5. Customer replacement units
This chapter provides instructions for adding certain components to the blade
server. Some removal instructions are provided in case you need to remove one
option to install another.
Installation guidelines
Before you begin to install options in the blade server, read the following
information:
v
Read Appendix B, “Safety information,” on page 97 and the guidelines in
“Handling static-sensitive devices.” This information will help you work safely with
the blade server and options.
v
Back up all important data before you make changes to disk drives.
v
For a list of supported options for the blade server, go to http://www.ibm.com/pc/
us/compat/.
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 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.
System reliability considerations
To help ensure proper cooling and system reliability, make sure that microprocessor
socket 2 always contains either the microprocessor heat sink filler or a
microprocessor and heat sink.
Handling static-sensitive devices
Attention:
Static electricity can damage electronic devices and the system. To
avoid damage, keep static-sensitive devices in their static-protective packages until
you are ready to install them.
To reduce the possibility of damage from electrostatic discharge, observe the
following precautions:
v
Limit your movement. Movement can cause static electricity to build up around
you.
v
Handle the device carefully, holding it by its edges or its frame.
v
Do not touch solder joints, pins, or exposed printed circuitry.
v
Do not leave the device where others can handle and possibly damage the
device.
v
While the device is still in its static-protective package, touch it to an
unpainted
metal part of the BladeCenter unit or any
unpainted
metal surface on any other
