Before you install the compute node in a chassis, read “Safety” on page v and “Installation guidelines”
on page 75.
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.
To install the compute node in a chassis, complete the following steps.

Step 1.
Select the node bay.
Notes:
1. If you are reinstalling a compute node that you removed, you must install it in the same node
bay from which you removed it. Some compute node configuration information and update
options are established according to node bay number. Reinstalling a compute node into a
different node bay can have unintended consequences. If you reinstall the compute node into
a different node bay, you might have to reconfigure the compute node.
2. To maintain proper system cooling, do not operate the Lenovo ThinkServer n400 Enclosure
Type 5495 chassis without a compute node, or node bay filler in each node bay.
Step 2.
Install the air baffle properly in the position before sliding the compute node.
Step 3.
Slide the compute node into the node bay until it stops.
Note:
The time required for a compute node to initialize varies by system configuration. The power
LED flashes rapidly; the power button on the compute node does not respond until the power LED
flashes slowly, indicating that the initialization process is complete.
Step 4.
Turn on the compute node (see “Turning on the server” on page 29 for instructions).
Step 5.
Make sure that the power LED on the compute node control panel is lit continuously, indicating
that the compute node is receiving power and is turned on.
Step 6.
If you have other compute nodes to install, do so now.
