SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
ASPIRE-400
(b) The number of data bits is 8 bits.
(c) The number of stop bits is 1 bit.
(d) The parity is None.
(e) The flow control is None.
(11) During "Normal Switching-On", the ACD POST and Commanded Self-Test de-assert the
Dual System Select (DSS) discrete.
(12) If SDU startup is due to automatic reset for "data load programming NVM variable set"
the SDU enters Data Loading Mode.
(13) The SDU transmits within 40 seconds of powering on the following labels:
(a) CFDS Label 350.
NOTE: This does not indicate self-test is completed. However, the SSM fields
need to indicate self-test if POST has not completed. When SSM
fields indicate self-test, the data is assumed to have no validity.
4. SDU Application Startup and Test
A. SDU Equipment Configuration
(1) With the exception of Boot Stage 1 errors, the SDU tolerates single bit errors of the Non-
Volatile Memory used to store program and data structures that are critical to the
operation of the system function.
NOTE: The functions considered critical to the system are the Channel Card Side A
and the ACD Processor which are used to provide the SBB Safety Services.
B. Validation
(1) During SDU Application Start-up and Test, the CC verifies the presence and correct
functionality of the USIM in the SCM.
NOTE: POST will not complete if the SCM does not reach operating temperature.
(a) The ACD:
1 Performs AISD and PIESD User ORT validation
2 Merges the SDU User ORT domain validation results.
(b) The SDU:
1 Performs APP and CC software validation
2 Validates operationally critical APP and CC non-volatile memory
3 Performs ACD, AISD, and PIESD Secure ORTcontent validation
4 Merges the SDU Secure ORT domain validation results
5 Performs licensing validation to determine if all licenses that are required
to enable ORTselected features are valid in the SCM
6 Validates the AP processor PIES/AIS security segmentation.
(2) An ORT file is considered valid if:
(a) The file checksum is correct.
(b) The file part number and version are compatible with the SDU Application
Software.
