3746-900 Diagnostic Description
The 3746-900 diagnostics are composed of:
¹
The basic assurance tests (BATs) which are
of two types:
– BATs which are located in the EEPROM
of each processor
–
Loaded BATs which are on the service
processor disk.
They test the common part of the processor
(microprocessor, bus, storage, DSI and switch
bus adapter).
¹
The specific assurance tests (SATs) which
are located on the service processor disk and
loaded as required in the processor to test
TIC3, ESCC, CS, SAS Bus and interfaces.
¹
The manual assurance tests (MATs) which
are located on the service processor disk and
loaded as required in the processor to test
part of the 3746-900. These diagnostics
prompt the CE to perform specific operations
such as, plug, unplug, install wrap, and so on.
They run under the control of the DCM.
Both BATs and SATs use the self-test capabilities
of the 3746-900 modules.
They report the errors via the SRCs on the service
processor console when the link to the service
processor is operational. BATs of the CBSP
report errors on the 3746-900 panel when the link
to the service processor is not operational.
