• When you install your new compute node, take the opportunity to download and apply the most recent
firmware updates. This step will help to ensure that any known issues are addressed and that your
compute node is ready to function at maximum levels of performance. To download firmware updates for
your compute node, go to http://www.ibm.com/support/fixcentral.
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/.
• Before you install optional hardware, make sure that the compute node is working correctly. Start the
compute node, 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 compute
node is otherwise working correctly. If the compute node is not working correctly, see "Running DSA
Preboot diagnostic programs" on page 57 for information about how to run diagnostics.
• Observe good housekeeping in the area where you are working. Place removed covers and other parts
in a safe place.
• 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.
• Make sure that you have an adequate number of properly grounded electrical outlets for the compute
node, monitor, and other devices.
• Back up all important data before you make changes to disk drives.
• Have a small flat-blade screwdriver, a small Phillips screwdriver, and a T8 torx screwdriver (provided
on the back of the chassis) available.
• To view the error LEDs on the system board and internal components, leave the compute node connected
to power.
• You do not have to turn off the compute node 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 compute node
before you perform any steps that involve removing or installing adapter cables and you must disconnect
the power source from the compute node before you perform any steps that involve removing or installing
a riser card.
• Blue on a component indicates touch points, where you can grip the component to remove it from or
install it in the compute node, open or close a latch, and so on.
• 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 compute node and operating system support hot-swap
capability, you can remove or install the component while the compute node 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.
• When you are finished working on the compute node, reinstall all safety shields, guards, labels, and
ground wires.
