LED Test Sequence at Startup
During startup, the NIE automatically initiates an LED test to verify the operational status of the LEDs. Immediately
after power is supplied to the NIE, the following LED lighting sequence occurs:
1. The POWER, BATT FAULT, 10 LINK, FAULT, RUN, and PEER COM LEDs turn On, indicating that the operating
system (OS), is starting. (After 2 seconds, the LEDs may change states depending on the site-specific network
activity.)
2. The BATT FAULT, PEER COM, and FAULT LEDs shut Off. The RUN LED flashes to indicate that the NIE
software is loading.
3. The LEDs display the operational status of the NIE. When the RUN LED goes On Steady, startup is complete
and the NIE is operational.
The total time to start up the NIE depends on the size of the database and can take several minutes.
