Maintenance Analysis Procedures (MAPs)

The maintenance analysis procedures (MAPs) provide the service representative a step-by-step procedure
to analyze a problem with the system and I/O subsystem hardware. Be prepared to record code numbers
and other data while using the MAPs.
Because the Model D10 and Model D20 are subsystems, refer to your system's service guide. The
system's service guide contains all of the MAPs needed for servicing the Model D10 and Model D20 I/O
subsystems.

Checkpoints

Checkpoints display on the system operator panel and the virtual terminal while the system unit is
powering on and going through the initial program load (IPL). See the system's service guide for
descriptive information and a complete listing of all checkpoints used by the Model D10 and Model D20
I/O subsystems.

Error Code to FRU Index

The Error Code to FRU Index lists fault symptoms and possible causes. The most likely cause is listed
first. Use this index to help you decide which FRUs to replace when servicing the Model D10 or Model
D20 I/O subsystem. See your system's service guide for more information and a complete listing of all
error codes and FRUs used by the Model D10 and Model D20 I/O subsystem.

Using the Service Processor

The service processor is in the processor subsystem to which your I/O subsystem is connected and runs
on its own power boundary. The service processor continually monitors hardware attributes and the
environmental conditions within the system and connected I/O subsystems. The service processor is
controlled by firmware and does not require the operating system to be operational to perform its tasks.
The service processor menus allow you to configure service processor options, as well as enable and
disable functions.
Service processor menus are available using an ASCII terminal or an HMC virtual terminal window when
OK is displayed on the operator panel or when the service processor has detected a system problem (such
as a surveillance failure).
For more information about the service processor for the system to which your I/O subsystem is
connected, see the system's service guide.

Using System Management Services

Use the system management services menus to view information about the processor subsystem to which
the I/O subsystem is connected. For more information about the service processor, see the service guide
for the attached system.
