Power down your iSeries system unit

You need to power down your system unit before you can connect your new expansion unit to it. All
system units in a cluster must be powered down. Follow the steps below to power down your system
unit.
__ 1. Ensure that you have a current backup of your operating system and licensed programs. If you
have backed up the operating system and licensed programs since the last time you applied
program temporary fixes (PTFs), that backup is acceptable.
__ 2. If you have installed logical partitions on your system unit, refer to Logical partitions in the iSeries
Information Center. In the iSeries Information Center you can find instructions on powering down a
system with logical partitions.
__ 3. If an IXA is present on the system, shut it down using the OS/400
__ 4. Ensure that all jobs are complete.
__ 5. When all jobs are complete, type pwrdwnsys *immed on a command line and press the Enter key.
Note: If you encounter difficulties during the installation, contact your authorized dealer or service
provider.
__ 6. After your system unit has completely powered down, power off all PCs and devices, such as
printers and display stations, that are connected to the system unit.
__ 7. Unplug any power cords, such as for printers, expansion units, and display stations, that are
connected to the system unit.
__ 8. Unplug all the power cords for the system unit from the electrical outlet.
__ 9. Did you receive a 7002 internal flex cable with your expansion unit?
__ No: Go to Chapter 2, "Set up your expansion unit," on page 13.
__ Yes: Go to "Installing the 7002 cable" on page 8.
