Common procedures for servicing or installing features in the
8001-12C or 8005-12N
Learn about the common procedures related to installing, removing, and replacing features in the IBM
Power System S821LC (8001-12C) system.
Before you begin
Observe these precautions when you are installing, removing, or replacing features and parts.
About this task
These precautions are intended to create a safe environment to service your system and do not provide
steps for servicing your system. The installation, removal, and replacement procedures provide the
step-by-step processes that are required to service your system.
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:
v 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.
v Do not open or service any power supply assembly.
v Do not connect or disconnect any cables or perform installation, maintenance, or reconfiguration of this
product during an electrical storm.
v 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.
v 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.
v Connect any equipment that will be attached to this product to properly wired outlets.
v When possible, use one hand only to connect or disconnect signal cables.
v Never turn on any equipment when there is evidence of fire, water, or structural damage.
v Do not attempt to switch on power to the machine until all possible unsafe conditions are corrected.
v 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.
v Do not continue with the inspection if any unsafe conditions are present.
v Before you open the device covers, unless instructed otherwise in the installation and configuration
procedures: Disconnect the attached AC power cords, turn off the applicable circuit breakers located in
the rack power distribution panel (PDP), and disconnect any telecommunications systems, networks,
and modems.
