  2. Take appropriate precautions for avoiding electric shock and handling static-sensitive devices. For information, see Avoiding electric shock and Handling static-sensitive devices.
  3. If you are removing a PCI adapter in a rack-mounted system or expansion unit, follow these steps. If you are servicing a stand-alone system, go to the next step.
  4. If you are removing a PCI adapter in a stand-alone system or expansion unit, follow these steps:
  5. Determine which adapters you plan to remove.
  6. Record the slot number and location of each adapter being removed.
    Note: Adapter slots are numbered on the rear of the system unit.
  7. Ensure that any processes or applications that might use the adapter are stopped.
  8. Enter the system diagnostics program by logging in as root user or as the celogin user, type diag at the AIX command line.
