Steady State LEDs
The LEDs of PNC components in a stable duplicated system should appear as follows:
● For an active ATM EI (functioning as Archangel) in a PN without IPSIs, its amber LED’s
flash pattern is 2 seconds on/200 ms off.
● For a standby ATM EI in a PN without IPSIs, it’s amber LED is off.
● For an active ATM EI in a PN with IPSIs, its amber LED is on steady.
● For an standby ATM EI in a PN with IPSIs, its amber LED is off.
PNC State of Health
PNC-DUP software monitors the health of the two PNCs as determined by their state-of-health
(SOH) vectors, and initiates an interchange when the health of the active falls below that of the
standby (unless prevented from doing so by a PNC lock, busyout, or antithrashing mechanism).
Potentially service-disrupting faults that occur in a PNC’s components are reported to
PNC-DUP and incorporated in the affected PNC’s state of health. The SOHs of both PNCs are
displayed on the status pnc screen, as shown in Figure 31: Status PNC screen with standby
PNC fully In-Service on page 590.
