2.9.5.2.1 Emergency Action Interface (EAI) Validity
After requesting the emergency action display page by depressing the EMER DISP
function key, the video terminal digit indicator must be checked to ensure a valid
display. The video terminal indicator is located in the upper center portion of the
display (Figure 2-33). The video terminal digit indicator consists of the maintenance
teletypewriter (MTTY) or maintenance cathode ray tube/terminal (MCRT) followed by
a numeric digit displayed in dynamic text. The digit is increased every 2 seconds. If
this indicator is not displayed and is not increasing, the entire display is invalid.
Once the validity of the display is determined, other indicators are used to qualify EAI
and emergency functions. Table 2-9 summarizes these indicators.
Note: The rest of the indicators on the display are valid only for EAIs indicating All
Seems Well (ASW).
2.9.5.2.2 Emergency Action Interface Indicator Area
The EAI indicators reflect the progress of the emergency action. The emergency action
is progressing successfully if the ASW indication is present (Figure 2-33).
The Control Unit (CU) status area is located at the upper left portion of the EAI page
display (Figure 2-33). This area informs the maintenance personnel which of the CUs
is active and which is on- or off-line. The term CU refers to the control unit or the AW.
At the upper right portion of the EAI page display is the Processor Recovery Message
(PRM) area (Figure 2-33). The PRMs display the systems coded failure/success
recovery information. The PRMs change continuously during an initialization,
reflecting the current state.
