Avaya 03-300430 User Manual

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-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
