9.
Press the light path diagnostics panel securely in the bracket.
10.
Install and close the compute node cover. See “Installing and closing the compute node cover” on
page 34.
Statement 21
CAUTION:
Hazardous energy is present when the compute node is connected to the power source. Always
replace the compute node cover before you install the compute node.
11.
Install the compute node into the IBM Flex System Enterprise Chassis. See “Installing the compute
node in an IBM Flex System Enterprise Chassis” on page 92.
12.
If you replaced the part because of a service action, verify the repair by checking that the amber
enclosure fault LED is off. For more information, see “Compute node control panel button and
LEDs” on page 9.
Removing and replacing FRUs (trained service technician only)
About this task
A FRU must be installed only by trained service technicians.
Removing a microprocessor and heat sink
Learn how to remove the microprocessors from a compute node to replace a failing part or as part of
another service procedure.
About this task
To remove a microprocessor and heat sink, complete the following steps:
Procedure
1.
Read the Safety topic and the “Installation guidelines” on page 29.
2.
Shut down the operating system on all partitions of the compute node, turn off the compute node,
and remove the compute node from the IBM Flex System Enterprise Chassis. See “Removing the
compute node from an IBM Flex System Enterprise Chassis” on page 31.
3.
Carefully lay the compute node on a flat, static-protective surface, with the cover side up.
4.
Open and remove the compute node cover. See “Removing the compute node cover” on page 33.
5.
Locate the microprocessor that is to be removed. See “System-board layouts” on page 11.
6.
Open the packaging of the new microprocessor, and place the cover upside down next to the tray, as
shown in Figure 31 on page 70. The cover will be used for the microprocessor that you are replacing.
