32. Have the customer reset the system date and time through the operating system that is installed.For more information, see the documentation for your operating system.33. If the part was replaced because of a service action, verify the repair by checking that the amberenclosure fault LED is off. For more information, see “Compute node control panel button andLEDs” on page 11.What to do nextAfter replacing the system-board and chassis assembly, you must either update the system with the latestfirmware or restore the pre-existing firmware.Completing the installationTo complete the installation, you must install and close the compute node cover, install the compute nodeinto the IBM Flex System Enterprise Chassis, and turn on the compute node.Procedure1. Install and close the compute node cover. See “Installing and closing the compute node cover” onpage 41.Statement 21CAUTION:Hazardous energy is present when the compute node is connected to the power source. Alwaysreplace the compute node cover before installing the compute node.2. Install the compute node into the IBM Flex System Enterprise Chassis. See “Installing the computenode in an IBM Flex System Enterprise Chassis” on page 93.3. Turn on the compute node, as described in “Turning on the compute node” on page 12.Note: If you have just connected the power cords of the IBM Flex System Enterprise Chassis toelectrical outlets, you must wait until the power-on LED on the compute node flashes slowly beforeyou press the power-control button.4. If you installed an I/O expansion card, use the documentation that comes with the expansion card toinstall device drivers and to perform any configuration that the expansion card requires.5. For certain optional devices, run the compute node SMS Utility program, as described in “Using theSMS utility” on page 24.90 Power Systems: IBM Flex System p260 and p460 Compute Nodes Installation and Service Guide
