The firmware can be installed from asupported and running operating system on the POWER-based blade or from the SDMC. Thefirmware can also be installed on a blade when booted from standalone AIX diagnostics.Power Systems has a permanent firmware boot side, or A side, and a temporary firmwareboot side, or B side.
