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.
For additional information about tools for updating, managing, and deploying
firmware, see the ToolsCenter for System x and BladeCenter at
http://publib.boulder.ibm.com/infocenter/toolsctr/v1r0/.
v Before you install optional hardware, 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 the Problem
Determination and Service Guide on the IBM System x Documentation CD for
diagnostic information.
v Observe good housekeeping in the area where you are working. Place removed
covers and other parts in a safe place.
v If you must start the server while the server cover is removed, make sure that
no one is near the server and that no tools or other objects have been left inside
the server.
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 can 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 server, monitor, and other devices.
v Back up all important data before you make changes to disk drives.
v Have a small flat-blade screwdriver, a small Phillips screwdriver, and a T8 torx
screwdriver available.
v You do not have to turn off the server to install or replace hot-swap power
supplies, hot-swap fans, or hot-plug Universal Serial Bus (USB) devices.
However, you must turn off the server before you perform any steps that
involve removing or installing adapter cables and you must disconnect the
power source from the server before you perform any steps that involve
removing or installing a riser card.
v Blue on a component indicates touch points, where you can grip the component
to remove it from or install it in the 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 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.
v When you are finished working on the server, reinstall all safety shields, guards,
labels, and ground wires.
