Use power isolation procedures for isolating a problem in the power system. Use isolation procedures if there is no HMC attached to the server. If the server is connected to an HMC, use the procedures that are available on the HMC to continue FRU isolation.
Some field replaceable units (FRUs) can be replaced with the unit powered on. Follow the instructions in System FRU locations when directed to remove, exchange, or install a FRU.
The following safety notices apply throughout the power isolation procedures. Read all safety procedures before servicing the system and observe all safety procedures when performing a procedure.
