Removing and replacing parts in the 9006-12P
system
Use these procedures to remove and replace failing parts in the IBM Power
system. These parts are referred to as field replaceable units (FRUs).
Note: See the International Information Bulletin for Customers - Installation of IBM Machines (http://
www.ibm.com/e-business/linkweb/publications/servlet/pbi.wss). This bulletin (Publication number
SC27-6601-00) provides a list of the key IBM system installation activities and those activities that might
be billable activities.
Before you begin a replacement, complete these tasks:
1. If you are completing 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.
• The color terracotta on the part indicates you might not need to power off the system to complete
service. This determination depends on your system configuration, and you might need to complete
steps to prepare the system before a service action can be completed on the system with the system
power turned on.
• The color blue on the part indicates that the procedure might require the system to be shut down
before servicing. Check your service procedure before you attempt the repair.
4. Ensure that you have access to a medium, flat-blade screwdriver, and a Phillips screwdriver.
5. If parts are incorrect, missing, or visibly damaged, contact the provider of the part or your next level of
support.
DANGER: When working on or around the system, observe the following precautions:
Electrical voltage and current from power, telephone, and communication cables are hazardous.
To avoid a shock hazard:
• If IBM supplied the power cord(s), connect power to this unit only with the IBM provided power
cord. Do not use the IBM provided power cord for any other product.
• Do not open or service any power supply assembly.
• Do not connect or disconnect any cables or perform installation, maintenance, or reconfiguration
of this product during an electrical storm.
• The product might be equipped with multiple power cords. To remove all hazardous voltages,
disconnect all power cords.
– For AC power, disconnect all power cords from their AC power source.
– For racks with a DC power distribution panel (PDP), disconnect the customer's DC power
source to the PDP.
• When connecting power to the product ensure all power cables are properly connected.
– For racks with AC power, connect all power cords to a properly wired and grounded electrical
outlet. Ensure that the outlet supplies proper voltage and phase rotation according to the
system rating plate.
– For racks with a DC power distribution panel (PDP), connect the customer's DC power source
to the PDP. Ensure that the proper polarity is used when attaching the DC power and DC power
return wiring.
• Connect any equipment that will be attached to this product to properly wired outlets.
