4.1.1. Power Supply/Error Code Test Indicator
PWR/PAT Green/Yellow:
Steady Green, built-in power works in good condition.
Yellow, when using built-in error code test function, if the fiber interface receives its own
sending pseudo random sequence data the indicator will be in steady yellow. When it gets
an error code the indicator will turns to green for at least 1 second.
Steady off, the device is power off.
4.1.2. Fiber Interface and Fiber Interface Alarm Indicator
For RC801-60B-FV35 dual strand device, TX stands for optical signal output (transmit)
and RX stands for input (Receive).
For RC803/5-60B-FV35 single strand device, TX and RX has no actual meanings. In one
fiber the transmission and receiving can be distinguished by different wave length.
LOS Red:
Steady light: Local optical receiving signal is lost;
Periodically flash: Remote optical receiving signal is lost;
Steady off: Local/remote optical receiving signal is normal.
LOF Red:
Steady light: Local optical receiving signal is out of frame;
Periodically flash: Remote optical receiving signal is out of frame;
Steady off: Local/remote optical receiving signal is not out of frame.
ERR Yellow:
Steady light: There is 1E-6 error code alarm in local optical receiving signal;
Periodically flash: There is 1E-6 error code alarm in remote optical receiving signal;
