LED definitions
The following table describes the LED definitions.
LED Description
LED 1
FPGA successfully programmed.
LED 2
Data capture in progress.
LED 3
Reserved.
LED 4
Transmitter laser ON.
LED 5
SD. Signal Detect. Illuminates when light is detected.
LED 6
LOF. Loss of frame. Illuminates the framer loses lock on a
valid SONET/SDH stream.
LED 7
PPS Out: Pulse Per Second Out – flashes indicate card is
sending a clock synchronization signal.
LED 8
PPS In: Pulse Per Second In – flashes indicate card is
receiving an external clock synchronization signal.
Description
The
dagfour
utility supports configuration status and physical layer
interface statistics for the DAG 4.3S. In a troubleshooting configuration
options
–si
should be passed to the tool to watch the operational status of
the optical, SONET and framing layers. More details about the meaning of
the various bits are supplied through the help page
(dagfour –h)
as well
as via the manual page.
