17. SYSTEM DIAGNOSIS
(only when the N-8000MI/8000DI/8000AF is used)
The N-8000MI/8000DI/8000AF diagnoses the system condition, and provides its results at the contact output
terminal as open or closed contact. The system diagnosis is performed in a way that the N-8000MI/8000DI/8000AF
connects the target equipment via the network.
The contact output terminal is closed only when an abnormality has been detected.
Thereafter, its closed terminal opens when the N-8000MI/8000DI/8000AF judges the condition to be normal.
This function aims to diagnose the exchange's line status and the network status of the connected equipment.
Use the N-8000 Setting Software to perform settings for the network lines and equipment to diagnose. (Refer
to p. 5-49 , 5-110, 5-117 .)
Note
Diagnosis is performed at the set time intervals*. Therefore, the diagnosis results are not obtained in real time.
The system condition, even if a change occurs, cannot be detected in the intervals from a diagnosis to the next
diagnosis.
* Diagnosis results are renewed every 20 seconds or less.
17.1. Line status diagnosis
If the N-8000EX or N-8010EX exchange's line to be diagnosed shows the status below, the N-8000MI/8000DI
/8000AF judges the line to be abnormal.
• Station's CPU failure
• Line synchronization error
• Station number registered but not connected
17.2. Network status diagnosis
The N-8000MI/8000DI/8000AF attempts to communicate with the network-connected equipment to be
diagnosed such as exchange, various kinds of interface unit, or IP station. If no response is detected, the
N-8000MI/8000DI/8000AF judges such equipment to be failed.

Diagnosis results can be displayed on a status indicator.
