To avoid potential danger, make sure to read and follow the safety information.
Attention: Read
“Installation Guidelines” on page 41 and “Safety inspection checklist” on page 42 to make
sure that you work safely.
Procedure
Step 1. Make preparations for this task.
a. Power off the node (see “Power off the node” on page 51); then, disconnect all external cables
from the node.
b. Remove the node from the chassis (see
“Remove a node from the chassis” on page 72); then,
carefully lay the node on a flat, static-protective surface, orienting the node with the front
toward you.
Notes:
• When removing the node, note the node tray number and make sure to install the node in
the same tray from which it was removed. Reinstalling the node into a different tray requires
the node to be reconfigured.
• For safety, make sure to hold the node with both hands when lifting the node.
Step 2. Remove the top cover from the node.
a.
Press the release buttons on the side and the top of the top cover.
b.
Slide the top cover toward the rear of the node; then, lift it up from the node and place it on a
flat and clean surface.
Important:
• Service label is located on the inside of the top cover (see
“Identify the system and access
the Lenovo XClarity Controller” on page 35
).
• For proper cooling and air flow, install the top cover before powering on the node.
Operating the node with the top cover removed might damage the components.
