Chapter 1. Removing and replacing FRUs
Use these procedures to remove and replace failing parts.
Before you begin a replacement, perform these tasks:
1. If you are performing a replacement procedure that might put your data at risk, ensure, if possible,
that you have a current backup of your system or logical partition (including operating systems,
licensed programs, and data).
2.
Review the installation or replacement procedure for the feature or part.
3. Note the significance of color on your system.
Blue or terra-cotta on a part of the hardware indicates a touch point where you can grip the hardware
to remove it from or install it in the system, open or close a latch, and so on. terra-cotta might also
indicate that the part can be removed and replaced with the system or logical partition power on.
4. Ensure that you have access to a medium, flat-blade screwdriver.
5. If parts are incorrect, missing, or visibly damaged, contact the provider of your parts, or your next
level of support.
