The installation, removal, and replacement procedures provide thestep-by-step processes 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 avoida 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 thisproduct 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 tothe 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 electricaloutlet. Ensure that the outlet supplies proper voltage and phase rotation according to the systemrating plate.– For racks with a DC power distribution panel (PDP), connect the customer’s DC power source tothe PDP. Ensure that the proper polarity is used when attaching the DC power and DC powerreturn 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 checksspecified during the subsystem installation procedures to ensure that the machine meets safetyrequirements.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 configurationprocedures: Disconnect the attached AC power cords, turn off the applicable circuit breakers located inthe rack power distribution panel (PDP), and disconnect any telecommunications systems, networks,and modems.DANGER:v Connect and disconnect cables as described in the following procedures when installing, moving, oropening covers on this product or attached devices.To Disconnect:© Copyright IBM Corp. 2014, 2017 19
