Operation: Network Activity (Status) Indicators
STATUS INDICATORS
Network activity LEDs
The eight status indicator LEDs display the operating condition of the RAVE unit and its connection to the Ethernet network. They are color coded such that green LEDs, when illuminated, signify a good or normal condition, while red LEDs signify a problem. The “Conductor” LED is yellow and simply indicates whether the unit is providing system synchronization and ac- cessibility functions.
Link
This LED illuminates green when the unit has established a link to an operating Ethernet network. In normal operation, this LED remains constantly lit, as long as the circuitry detects the network carrier. If this LED is not illuminated, there is a fault, possibly at the network device or in the cable connection. Note that this indicator does not confirm that the link is 100 Mbps or that the network device is supported by RAVE.
100 Mbps
This LED illuminates green when the unit establishes a link to a
Rx
This green LED lights for 50 milliseconds or longer whenever the unit receives Ethernet data, whether it is addressed to the unit or not. This indicator will blink when receive activity is present. The activity of this indicator is dependent on the RAVE model and bundle type. This is a physical layer indicator and does not guarantee that data is being received properly at the CobraNet core.
Rx Error
This red LED illuminates for at least 1 second if the unit has trouble receiving CobraNet related data. If illuminated, the failure may be due to problems with Ethernet reception, overcommitted transmission, excessive network delay or an internal fault. This indicator will also illuminate with the TxError LED if the device cannot synchronize to the network clock.
