(2) LRU Codes
BITE event information is encoded by the LRUs in three value
s. The values are named L1
thru L3:
• L1 denotes the LRU or interface (generated by an LRU on its behalf) which
is ge
nerating the event
• L2 denotes the Shop Replaceable Module within an LRU for a event relating
to an LR
U, or for interfaces it denotes a particular part of the interface which
is generating the event.
• L3 further defines the unique event that occurred.
Each fault or event also has an additional text field which can carry additional information
he
lpful to under
stand the fault or event that happened.
The combination of L1 thru L3 alone uniquely identifies a BITE event in the system.
(3) L1 Codes
(a) The event L1 code uses two hexadecimal digits to ide
ntify a LRU or an interface within
an AES LRU, coded as follows:

such as an invalid or unknown system configuration
error, or a system event not specific to an LRU.
