VO-4e Front
System Indicators
The LED indicators on the front panel provide information and operational status of the unit and
associated output channels. LEDs have been grouped into Chassis and Channel indicators.
Chassis Indicators
These indicators relate to the entire unit (chassis).
PoE
PoE is a green LED indicator that will illuminate when PoE power is applied to the unit via either or both
CobraNet ports.
Aux
Aux is a green LED indicator that will illuminate when an auxiliary DC supply is applied to the unit via
either or both 24V Auxiliary power inputs.
Chassis Fault
Chassis Fault is a amber LED indicator that illuminates when a Chassis Fault has occurred. There are
two types of Chassis Faults that can be reported depending on the severity of the problem. Flashing
amber indicates a Warning that means some aspect of the unit is not performing within normal
specification. Audio may still be passing but if the condition causing the warning is not corrected chassis
failure may occur. Solid amber indicates a fault which means that some aspect of the unit has failed and
audio may no longer be passing through the device. Use Vocia software to determine the specific type of
chassis warning or Fault that has occurred.
Activity
Activity is a two-color LED that indicates the configuration status of the device. A solid green LED
indicates that the unit is configured. A flashing yellow LED indicates the unit is active but unconfigured. A
solid yellow LED indicates the unit is configured and in standby. Standby only occurs when a unit has
been designated as a redundant device when Device Failover is enabled.
Status
Status is a tri-color LED that indicates the health of the hardware. A green LED indicates that the unit
powered up normally. A flashing amber LED is shown briefly during the power-up self-test and will turn
solid green upon successful start. A red LED indicates that the unit experienced a problem during the
power-up self-test.
Channel Indicators
These indicators relate to each of the four channels.
Amp Fault is a amber LED that illuminates when the corresponding Amp Fault Input on the rear of the
unit has been asserted.
Activity is a two-color LED that illuminates green when that channel is configured and actively passing
audio and yellow when that channel is configured and in standby. Standby only occurs when a channel
has been designated as redundant channel in a failover configuration.
Signal is a tri-color LED that illuminates in the following manner when audio signal is present. Detailed
metering of current output levels can be obtained in real time via the Vocia software interface.
