Power: Off State: System power off/State unknown Restart count: 137 Power-on hours: 465 hours Figure 4-35 RSA II Web interface: power-off state Solution and workaround A newer BMC firmware solves the incorrect reading of the power state that is reported by the field programmable gate array (FPGA) firmware code. You can work around this error by removing all systems in the partitions from the AC power source. Wait 30 seconds and then replug the AC power. We recommend that you regularly check for newer system firmware code and updated product publications such as the Problem Determination and Support Guide and new tips on the Support for IBM System Support Web pages at: http://www.ibm.com/systems/support/x As shown in Figure 4-36 on page 244, select your product family x3850 M2 or x3950 M2, or the machine type to find the required information.
