i5/OS
At the time of writing i5/OS® is not supported.
2.13 Service information
The 570 is not a client setup server (CSU). Therefore, the IBM service representative
completes the system installation.
2.13.1 Touch point colors
Blue (IBM blue) or terra-cotta (orange) on a component indicates a touch point (for electronic
parts) where you can grip the hardware to remove it from or to install it into the system, to
open or to close a latch, and so on. IBM defines the touch point colors as follows:
Blue
This requires a shutdown of the system before the task can be
performed, for example, installing additional processors contained
in the second processor book.
Terra-cotta The system can remain powered on while this task is being
performed. Keep in mind that some tasks might require that other
steps have to be performed first. One example is deconfiguring a
physical volume in the operating system before removing a disk
from a 4-pack disk enclosure of the server.
Blue and terra-cotta
Terra-cotta takes precedence over this color combination, and the
rules for a terra-cotta-only touch point apply.
2.13.2 Operator Panel
The service processor provides an interface to the control panel that is used to display server
status and diagnostic information. See Figure 2-26 on page 66 for operator control panel
physical details and buttons.
Note: IBM only supports the Linux systems of clients with a SupportLine contract covering
Linux. Otherwise, contact the Linux distributor for support.
Important: It is important to adhere to the touch point colors on the system. Not doing so
can compromise your safety and damage the system.
