NOTES:
1.
bbbbbbb represents the seven-digit LRU end-item base part number.
2.
hh represents the two-digit LRU end-item hardware configuration number.
3.
sss represents the three-digit LRU end-item software configuration number.
4.
nn represents the two-character LRU end-item software modification level (possibly including space, dash
characters, and alpha characters).

Following the display of all Level I failure messages, a list of the
available LRU end-item part numbers is displayed. This list only includes
part numbers for those LRUs present in the given installation as defined
by the system configuration pins (see MECHANICAL INSTALLATION).
For an installed LRU whose end-item part number is not available,
dashes are displayed in place of the part number (e.g., HPL _ _ _ _ _ _
_ _ _ _ _). The list of part numbers are displayed in the order given in
Table 6-6.
Table 6-6. List of Part Numbers
SDU bbbbbbb--hhsss--nn
HPH bbbbbbb--hhsss--nn
HPL bbbbbbb--hhsss--nn
HSU bbbbbbb--hhsss--nn
For the SDU, the two-digit LRU hardware configuration number must be
entered manually through the CMT interface for valid data to be
available for display. This data is stored during LRU end-item testing. All
other numbers reside within the LRU software. All numbers are
communicated to the SDU by Honeywell/Thales HSU and HPA(s)
through the part number block transfer. For non-Honeywell/Thales
interfacing HPAs, no such data is available to the SDU, therefore,
dashes are displayed for the HPA end-item part number.
Following the display of the LRU End Item part numbers, the ICAO
aircraft address is displayed in octal and hexadecimal formats as shown
below:
ICAO--XXXXXXXX YYYYYY
Where "XXXXXXXX" represents the octal format and "YYYYYY"
represents the hexadecimal format. If the ICAO is provided from an
ARINC 429 source, as determined by the state of configuration pin
TP10A, and a valid ICAO has not been received, the octal and
hexadecimal values are replaced with dashes.
