2.0.0 Where to Obtain the Firmware

This firmware can be found at the following locations:

From the IBM Tech Support Website as individual files (http://www14.software.ibm.com/webapp/set2/firmware/gjsn
) :
1. Look for Power Subsystem for: 9119-595, 9406-595, 9119-590, 9118-575 in the Model column
2. Click on RPM(linux) to download the RPM file
3. Click on XML to download the XML file
4. Load both of these files on the HMC (see section 2.0.1 How to Load the Firmware below)
From the IBM Tech Support Website as a CD-ROM image (http://www14.software.ibm.com/webapp/set2/firmware/gjsn?mode=10&page=cdrom.html) :
Use this image file in conjunction with a computer that is capable of creating CD-ROMs.
NOTE: This CD-ROM image also contains System Firmware

2.0.1 How to Load the Firmware

IMPORTANT NOTE:
Before attempting to load this firmware please ensure that your HMC software has been upgraded to the latest level for "servers with POWER5 processors". HMC software packages can be found at: https://www14.software.ibm.com/webapp/set2/sas/f/hmc/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.
