1.9.2 NE 900 D Cobra Status LEDs
The LINK, ACTIVITY and FAULT CobraNet LEDs indicate the status of the CobraNet network
connection.
The LINK LED illuminates only when the Ethernet cable is connected to a network with other
CobraNet devices.
The ACTIVITY LED is on only when there is a match between the bitwidth/latency and bundle settings
of the NE 900 D Cobra and those of the receiving device.
The FAULT LED is used to blink a numeric code to the user with a series of blinks followed by a
pause. The number of blinks indicates the following:
1. Mismatched format or bundle settings.
2. Not used on NE 900 D Cobra.
3. Invalid bundle number selected (> 65279).
4. Ethernet cable disconnected or no other CobraNet devices on network.
5. CobraNet cannot communicate with DSP in the NE 900 D Cobra.
