LED Label Color State Function
ACTIVE Off Off The SPA port is not enabled by the
field-programmable gate array (FPGA).
The SPA port does not have any frame activity on
RX/TX Layer 1.
Green Blinking The SPA port is enabled by the FPGA, and it has
Rx/Tx Layer 1 frame activity.
Amber On This state is unused.
CD/LB Off Off The SPA port is not enabled.
Green On The SPA port is enabled, and DTR, DSR, RTS,
CTS, or DCD is active.
Amber On The SPA port is enabled, and local loopback or
internal loopback is active.
STATUS Off Off The SPA is powered off (power is not within
required specification) or Status On conditions
are not met.
Green On The SPA is powered on and operational (power is
within required specifications and initialization
is complete).
The following conditions must be met before the
STATUS LED goes on:
• The SPA is correctly connected and
receiving power.
• The SPA-equipped card or router contains a
valid microcode version that has been
downloaded successfully.
• The bus recognizes the SPA.
• The SPA is up to date on the FPD versions
required by the router software.
Amber On The SPA is powered on but initializing (power is
within required specifications, but the hardware
and software initialization sequence is not
complete).
