Removing A 1-Bay Compute Node; Replacing A 1-Bay Compute Node - Lenovo NeXtScale n1200 Installation And Service Manual

Removing a 1-bay compute node

Use these instructions to remove a 1-bay compute node from the NeXtScale n1200 Enclosure.
Attention: To maintain proper system cooling, do not operate the chassis without a compute node or
compute node filler in each node bay. Install a compute node or filler within one minute of the removal of a
compute node.
Before you remove a 1-bay compute node, complete the following tasks:
1. Make a note of the bay number. Reinstalling a compute node into a different bay from the one from
which it was removed can have unintended consequences. Some configuration information and update
options are established according to bay number.
2. Shut down the compute node operating system; then, shut down the compute node. See the
documentation that comes with your compute node for the procedure to shut down the operating
system.
To remove a 1-bay compute node, complete the following steps.

Step 1. Open the release handle (rotate the handle to the left) to disengage the compute node from the
chassis.
Step 2. Use both hands to slide the compute node out of the compute node bay and place it on a flat,
static-protective surface.

Use these instructions to install a 1-bay compute node in the NeXtScale n1200 Enclosure. You can install a
compute node while the chassis is powered on.
