5.1 Error Detection
Power-Up Self-Test
AirMux-200 performs a hardware test of the IDU upon turn-on. This
self-test checks the critical circuit functions of the unit. The RTCB LED
indicates results of the self-test (see Chapter 4 for LED descriptions).
Alarms
AirMux-200 detects fault conditions of the radio and user links and
initiates alarms to alert the user. The user can save the alarm log as a
TXT file.
Alarms are displayed in the Event Log (see Figure 5-1).
The event log includes the following fields:
• Alarm sequential number
• Date and time stamp
• Message
• Alarm source (local or remote ODU)
• IP address of the ODU that initiated alarm.
