Stage 48 8
Ethernet Snake Card
This section describes the front-panel features of the Ethernet Snake card. The Ethernet Snake card is installed in Mix Rack or SC48.
Ethernet Snake Ports
The Ethernet Snake card provides two pairs of Ethernet ports for
making primary and redundant digital snake connections to up to
two Stage 48 units.
Stage 1 Ports A and B
Port A is used for the primary snake connection and port B is for
the redundant snake connection to the first Stage 48.
Stage 2 Ports A and B
When using a second Stage 48, Stage 2 port A is used for the pri-
mary snake connection and port B is for the redundant snake con-
nection.
Snake Act and Sig LEDs
Each primary and redundant snake connection has its own Activ-
ity (Act) and Signal (Sig) LED. The system is ready for use when
all Stage 48 units are connected and all Act and Sig LEDs are lit
solid.
Act LED
The Act LED lights solid to indicate that AVB Ethernet traffic is
currently active on the connected Snake. If a redundant snake is
connected, then both primary and redundant Act LEDs will be lit
for each connected Stage 48.
Sig LED
The Sig LED lights solid indicates that a valid communication
connection exists between the Stage 48 and console. If a redun-
dant snake is connected, then both primary and redundant Sig
LEDs will be lit for each connected Stage 48.
Status LED Indicator
The Status LED lights green, yellow, or red to indicate the status
of the Ethernet Snake card.
Recessed Pushbutton
Pressing and holding the Recessed Pushbutton for at least five (5)
seconds puts Stage 48 into firmware update mode.
