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 39.
5. Locate the thermal sensor as shown in Figure 33 on page 67.
6. For best visibility, orient yourself to the left of the compute node.
7. Using your left hand (for best visibility), squeeze the tab (A) on the sensor to dislodge the sensor
from its connector.
8. Pull the sensor out.
9. If you are instructed to return the thermal sensor, follow all packaging instructions, and use any
packaging materials for shipping that are supplied to you.
10. Press the new thermal sensor into the connector until it snaps into place.
11. Install and close the compute node cover. See “Installing and closing the compute node cover” on
page 41.
Statement 21
CAUTION:
Hazardous energy is present when the compute node is connected to the power source. Always
replace the compute node cover before installing the compute node.
12. 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 93.
13.
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 11.
Removing and replacing tier 2 CRUs
Use this information for removing and replacing tier 2 CRUs.
About this task
You can install a tier 2 CRU, or you can request IBM to install it, at no additional charge, under the type
of warranty service that is designated for the compute node.
Removing a DIMM
The very low profile (VLP) dual-inline memory module (DIMM) is a tier 1 CRU. You can remove it
yourself. If IBM removes a tier 1 CRU at your request, you will be charged for the removal. The low
profile (LP) DIMM is a tier 2 CRU. You can remove it yourself or request IBM to remove it, at no
additional charge, under the type of warranty service that is designated for the compute node.
