Table 48: LED Status of the WCA-PC-10G-V
WCA-PCN-2G5U
This subsection will help you resolve issues that can be experienced on WCA-PCN-2G5U modules.
It assumes that all measurements for the C/R, C/T, N/R East, N/R West, N/T West and N/T East interfaces are within ADVA Optical Networking specifications and that
you have verified that the application wavelength is the same as the wavelength for the FSP 3000R7 module’s client interface. If not, refer to “Finding Your Problem -
Follow the Light” on p.53.
CAUTION
Follow all the instructions precisely. If you do not supply the specified attenuation on given steps, you could destroy the module being tested. As soon as
the near-end and the far-end WCA-PCN-2G5U modules in a link are synchronized, the network link is up. The network interface LEDs light up solid green
or blink green depending on the configured transmission mode: Multiplexer NE Only, Multiplexer NW Only, Multiplexer NE & NW or Regenerator 1-Way.
