Use this information for installation.
Attention: Static electricity that is released
to internal compute node components when the compute node is powered-on
might cause the system to halt, which might result in the loss of
data. To avoid this potential problem, always use an electrostatic-discharge
wrist strap or other grounding system when removing or installing
a hot-swap device.
Before you install optional devices, read the following
information:
- Read the safety information in Safety and Handling static-sensitive devices. This
information will help you work safely.
- Make sure that the devices that you are installing
are supported. For a list of supported optional devices for the compute
node, see the Lenovo ServerProven website.
- 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 the Fix Central website.
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 the Lenovo ToolsCenter website.
- 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 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.
