Removing And Replacing Parts In The 9183-22X - IBM IC922 Servicing

Removing and replacing parts in the 9183-22X

Use these procedures to remove and replace failing parts in the IBM Power
system.
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. The color blue on the part indicates a touch point.
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.
• When possible, use one hand only to connect or disconnect signal cables.
• Never turn on any equipment when there is evidence of fire, water, or structural damage.
• Do not attempt to switch on power to the machine until all possible unsafe conditions are
corrected.
• Assume that an electrical safety hazard is present. Perform all continuity, grounding, and power
checks specified during the subsystem installation procedures to ensure that the machine meets
safety requirements.
• Do not continue with the inspection if any unsafe conditions are present.
