Troubleshooting Core Type WDM Channel Modules
Note
If your module has an LED status that is not represented in Table 34 on p.211, please contact
your ADVA Optical Networking Technical Services Representative.
The steps in this subsection may need to be completed on both sides of the link. Please follow the
troubleshooting steps in Table 34 based upon the states of the LEDs.
The WCC-PCN-100G has four LEDs on the faceplate:
• “P” to indicate the power supply status
• “Mod” to indicate the operation status of the module
• “C” and “N” to indicate the interface status
Note
When a module is removed, it should lose power for at least 10 seconds to allow any and all
capacitance to dissipate.
