Network Port Snake Act and Sig LEDs
Each S3 control surface, E3 engine, and Stage 16 Network port
has its own Activity (Act) and Signal (Sig) LEDs. Each device is
ready for use when the Act and Sig LEDs are lit solid for each
connected Network port.
Act LED The Act (activity) LED lights solid to indicate that AVB
Ethernet traffic is currently active on the connected audio snake
cable. If a redundant snake is connected, or if a Stage 16 is
daisy-chained to another Stage 16, then ports A and B Act LEDs
will be lit.
Sig LED The Sig (signal) LED lights solid to indicate that a valid
communication connection exists between devices. If a redun-
dant snake is connected, or if the Stage 16 is daisy chained to an-
other Stage 16, then ports A and B Sig LEDs will be lit.
Power and fan faults are also communicated on-screen via
a warning dialog box.
