Removing the compute node
Use this information to remove the compute node.
Notes:
1. This procedure should be performed only by trained service technicians.
2. Before you replace the system board, make sure that you backup any features on demand
(FoD) keys that were enabled. Reactivate any Features on Demand features after replacing the
system board. Instructions for automating the activation of features and installing activation
keys is in the
Lenovo Features on Demand User's Guide
. To download the document, go to

3. When you replace the system board, you must either update the server with the latest firmware or
restore the pre-existing firmware that the customer provides on a diskette or CD image. Make sure that
you have the latest firmware or a copy of the pre-existing firmware before you proceed.
4. When you replace the system board, make sure that you remove the Integrated Management Module
Advanced Upgrade and place it on the new system board. For information about the Advanced
Upgrade, see “Using the remote presence and blue-screen capture features” on page 39
Note:
You have to reactivate the Features on Demand (FoD) after replacing the system board.
Before you remove the compute node, complete the following steps:
1. Read “Safety” on page v and “Installation guidelines” on page 101.
2. If the compute node is installed in a NeXtScale n1200 Enclosure, remove it (see “Removing a compute
node from a chassis” on page 104 for instructions).
3. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with
the bezel pointing toward you.
4. Obtain the following for use during the replacement procedure (see Chapter 4 “Parts listing, Lenovo
NeXtScale nx360 M5 compute node” on page 85).
• Alcohol wipes (part number 59P4739)
• RFID tag (required only if the compute node came with a RFID tag attached to the bezel)
• T8 torx screwdriver (part number 00FK488, provided on the back of the chassis)
• Thermal grease kit (part number 41Y9292)
Important:
When you replace the system board, you must update the compute node with the latest
firmware or restore the preexisting firmware. Make sure that you have the latest firmware or a copy of the
preexisting firmware before you proceed.
See “System-board layouts” on page 22 for more information about the locations of the connectors,
jumpers, and LEDs on the system board.
