Chapter 4: Confidence Testing
Introduction
The confidence testing is a process to determine whether the DAG 4.2S
card is functioning correctly. The process also involves a card capture
session, and demonstrates configuration in the style of 'What You See You
Can Change', WYSYCC. Interface statistics are also inspected during this
process.
In this chapter This chapter covers the following sections of information.

4.1 Interpreting DAG Card LED Status
Description
The DAG 4.2S card has a block of 6 status LEDs, one blue, one yellow,
two green, one red and one orange.

LED definitions
The following table describes the LED definitions.
LED Description
LED 1 - Blue
FPGA successfully programmed.
LED 2 - Yellow Data capture in progress.
LED 3 - Green PPS synchronisation signal, flashes with valid input
signal.
LED 4 - Red Transmitter laser ON.
LED 5 - Green SD. Signal Detect, valid optical signal seen by the
optical receiver.
LED 6 - Orange LOF. Loss of Frame synchronization alarm, usually
caused by loss of signal.
