Figure 3-23. AES and LRU Controller Interaction
(g) The AES Controller resides in the Modman LRU.
(h) Each LRU Controller monitors the LRU for BITE events. BITE events are classified into
two categories:
• Faults: These are BITE events which have a SET state (occurring) or CLEAR state
(fault has disappeared).
• Events: These are BITE events which occur but do not have a set or clear state.
(i) The LRU records the BITE event into a specific LRU log, dependent on the type of fault
or event.
NOTE:
Not all BITE events indicate an error situation. BITE events are also used for
storing significant events in the historical logs, either on the LRU or in the AES
controller, or for informing the AES controller of important system wide
information.
(j) BITE events are sent to the AES controller. The AES controller may react to an event
by changing the overall state of the AES system. Actions include disabling the system,
rebooting the system, etc.
