Service Processor MAPs
CBSA IML With Diagnostics
¹
Reset CBSP.
¹
BATs test the CBSP, SPS, OP Panel and
TIC3 and the connection to the service
processor.
¹
IML the CPSP from the service processor
¹
Run the loaded BATs
¹
Load the CBSP environment from the service
processor
¹
From the service processor load and run the
SATs on the CBC.
The 3746-900 is now in standby.
Other Adapter IML With Diagnostics
¹
Reset the adapter.
¹
BATS are run on the processor of the
selected adapter and initialized.
¹
When the processor is initialized, it sends its
VPD via the CS.
¹
The operational code is loaded in the
processor. Then the VPD of the attached
coupler is sent to the CBSP and resource
status table (RST), and the configuration data
file extended (CDF-E) is updated.
¹
SATs are loaded and run on couplers.
¹
Operational code is loaded in each coupler.
¹
IML ends.
Online Tests (OLTs):
The online tests
(OLTs) for the ESCA are not supported and they
are replaced by the normal use of the link level
protocol of the serial I/O architecture.
3745/3746-900 Model 900 Diagnostics:
In order to test the interface between the 3745
and the 3746-900, the MOSS-Extended DMA bus
test and IOC bus test are invoked from the 3745
MOSS. In addition, the 3745 IPL diagnostic
checks the level 1 level 2 interrupt mechanism of
the 3746-900.
