Lenovo NeXtScale nx360 M5, Installation And Service Manual, Page: 119 / 1022

Attention:
• To maintain proper system cooling, do not operate the NeXtScale n1200 Enclosure without a
compute node or node bay filler installed in each node bay.
• When you remove the compute node, note the node bay number. Reinstalling a compute
node into a different node bay from the one it was removed from can have unintended
consequences. Some configuration information and update options are established according
to node bay number. If you reinstall the compute node into a different node bay, you might have
to reconfigure the compute node.
Step 2. Pull the compute node out of the node bay.
Step 3. Install either a node bay filler or another compute node in the node bay within 1 minute.
If you are instructed to return the compute node, follow all packaging instructions, and use any packaging
materials for shipping that are supplied to you.
Installing a compute node in a chassis
Use this information to install a compute node in a NeXtScale n1200 Enclosure.
Before you install the compute node in a chassis, read “Safety” on page v and “Installation guidelines” on
page 101.
Statement 21
CAUTION:
Hazardous energy is present when the compute node is connected to the power source. Always
replace the compute node cover before installing the compute node.
If you are installing a compute node model without an integrated Ethernet controller, you must install a
network interface adapter before you install the compute node in the chassis for management network
communication. For a list of supported optional devices for the compute node, see http://www.lenovo.com/
serverproven/.
To install the compute node in a chassis, complete the following steps.
