• Microprocessors, heat sinks, and microprocessor heat-sink fillers. Use the microprocessor
installation tool that comes with the replacement microprocessor to remove each microprocessor
from the system-board assembly and install each one immediately in the new system-board
assembly (see “Removing a microprocessor and heat sink” on page 162 and “Replacing a
microprocessor and heat sink” on page 165).
• Hard disk drive backplate (see “Removing the hard disk drive backplate” on page 139).
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 the compute node
Use this information to install the compute node.
Note: This procedure should be performed only by trained service technicians.
Before you install the compute node, complete the following steps:
1. Read “Safety” on page v and “Installation guidelines” on page 89.
2. If the compute node is installed in an IBM NeXtScale n1200 Enclosure, remove it (see “Removing a
compute node from a chassis” on page 92 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, IBM
NeXtScale nx360 M4 Compute Node Type 5455” on page 81).
• Alcohol wipes (part number 59P4739)
• Bezel
• 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 “Updating the firmware” on page 21 for more information.
To install the system-board assembly, complete the following steps.
Step 1. Install all of the components in the following list that you removed from the old system-board
assembly onto the new system-board assembly:
• DIMMs (see “Installing a memory module” on page 130).
• Air baffles (see “Replacing the air baffle” on page 109).
• Hard disk drives and hard disk drive fillers (see “Installing a 3.5-inch hard disk drive” on page
143, “Installing a 2.5-inch hard disk drive” on page 146, and “Installing a 1.8-inch hard disk
drive” on page 149).
• Microprocessors, heat sinks, and microprocessor heat-sink fillers. Use the microprocessor
installation tool that comes with the replacement microprocessor to remove each microprocessor
from the system-board assembly and install each one immediately in the new system-board
assembly (see “Removing a microprocessor and heat sink” on page 162 and “Replacing a
microprocessor and heat sink” on page 165).
• Hard disk drive backplate (see “Installing the hard disk drive backplate” on page 140).
After you install the compute node, complete the following steps:
