Removal and replacement procedures
Use the removal and replacement procedures when you repair, maintain, or exchange your system 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 Phillips screwdriver.
5. If parts are incorrect, missing, or visibly damaged, contact your service provider or next level of
support.
