Information document.

Installing an optional device

Some compute node components are available as both an optional device and a replaceable component.
The installation procedure is the same for the optional device and the replaceable component.

Installation guidelines

Before you remove or replace a FRU or install an optional device, read the following information:
• Before you begin, read
information will help you work safely.
• 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 the latest firmware
and device drivers, go to
System,Compute Node and x440 Compute Node.
• Observe good housekeeping in the area where you are working. Place removed covers and other parts in
a safe place.
• Back up all important data before you make changes to hard disk drives.
• Before you remove a compute node from the Flex System chassis, you must shut down the operating
system and turn off the compute node. You do not have to shut down the chassis itself.
• 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.
• For a list of supported optional devices for the compute node, see

System reliability guidelines

Use these guidelines to ensure that the compute node meets the cooling and system reliability requirements:
• To ensure proper cooling, the Flex System chassis is not operated without a compute node or node bay
filler in each node bay. See
Service Guide" at http://pic.dhe.ibm.com/infocenter/flexsys/information/topic/com.lenovo.acc.8721.doc/
for additional information.

• A socket cover and heat-sink filler or a microprocessor and heat sink must always be installed on
microprocessor sockets 1, 3, and 4. Microprocessor socket 2 will only have a socket cover when a
microprocessor is not install. If the compute node has only one microprocessor, it must be installed in
microprocessor socket 1.
• The air baffles are installed over the DIMM connectors.
