Tx
This LED illuminates green for at least 50 milliseconds while the unit is transmitting Ethernet data. This indicator will blink
when transmit 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 transmitted properly from the CobraNet core.
Tx Error
This LED illuminates red for at least 1 second if a unit is having trouble transmitting CobraNet related data. Failure here
may be due to network inaccessibility, duplicate transmit bundle assignments, improper network configuration or an inter-
nal fault. This indicator will also illuminate with the RxError LED if the device cannot synchronize to the network clock.
Conductor
This yellow LED will illuminate whenever the unit is acting as the system “conductor”. In this mode, the unit provides the
system synchronization and accessibility resources. Arbitration for the conductor role is initiated during system initializa-
tion or when a unit with a higher priority than the current conductor is added to the network. Conductor priority is based on
the transmission capabilities of the device. The device with the least amount of transmission requirements is the best
candidate for the conductor role. Currently, the hierarchy is as follows:
1.
RAVE 160s-24 and 80s
highest
2.
RAVE 188s-24 and 88s
mid position
3.
RAVE 161s-24 and 81s
lowest
In the event there are two or more units with the highest priority arbitrating for the conductor role, the MAC address will
be used as the deciding factor.
Note that there should be one, and only one, conductor per LAN or VLAN. Multiple conductor
indicators may point to an unintentional partition in the network architecture because of multicast
filtering.
Fault
This red LED illuminates whenever the unit detects an unexpected internal fault. If the RAVE unit cannot pass its self-
induced self-test (POST), the fault indicator will usually repeat a sequence of flashes, which indicates where the POST
failure occurred. If the RAVE does pass the self-test but cannot perform or continue its operation, a blink code consisting of
three flash patterns may be repeated on the fault indicator. Additionally, the RAVEs audio metering LEDs may display a
binary fault code. Fault codes are provided by Peak Audio for each major release of CobraNet code. When communicated
by the user, these front panel fault code displays may help QSC’s Technical Services department in providing a quick
remedy for a faulty RAVE unit.
