CAUTION: Hazardous energy present. Voltages with hazardous energy might cause heating when
shorted with metal, which might result in splattered metal, burns, or both. (L005)
Procedure
Before you begin a replacement or installation procedure, do these tasks:
1. If you are installing a new feature, ensure that you install the required software to support the new
feature. See IBM Prerequisite.
2. If you are installing or replacing something that might put your data at risk, ensure, wherever possible,
that you have a current backup of your system or logical partition (including operating systems,
licensed programs, and data).
3. Review the installation or replacement procedure for the feature or part.
4. Note the significance of color on your system.
Blue 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.
5. Ensure that you have access to a medium flat-blade screwdriver, a Phillips screwdriver, and a pair of
scissors.
6. If parts are incorrect, missing, or visibly damaged, do the following steps:
• If you are replacing a part, contact the provider of your parts or next level of support.
• If you are installing a feature, contact one of the following service organizations:
– The provider of your parts or next level of support.
– In the United States, the IBM Rochester Manufacturing Automated Information Line (R-MAIL) at
