2.0.1 How to Load the Firmware

IMPORTANT NOTE:
Before attempting to load this firmware please ensure that your HMC (Hardware Management Console) software has been upgraded to the appropriate version. HMC version information can be found at: http://www14.software.ibm.com/webapp/set2/sas/f/power5cm/home.html

The instructions regarding how to query, obtain, install and remove firmware levels can be found on the following IBM Infocenter Page: Getting server firmware and power subsystem firmware fixes and upgrades

2.1 Cautions and Important Notes

Never Turn Off the UEPO switch (red switch) During the Power Subsystem Firmware Update Process -- the update will fail, and the process must be repeated. Also, the power component being loaded could be permanently disabled.
Never Log Off of the HMC During the Power Subsystem Firmware Update Process -- the update will fail, and the process must be repeated.
Service any existing problems with the Power Subsystem prior to attempting to load Power Subsystem Firmware from the HMC. Outstanding problems can cause the Power Subsystem to be in an N-mode power state (which means there has been a loss of redundancy) and can prevent the HMC from being able to load the Power Subsystem Firmware.
