3.17.1 MIC-A/P Connector Pinouts
Note For proper system operation, both the MIC-A/P and the MIC-C/T/P FMECs must be installed in the
ONS 15454 SDH shelf.
Note The MIC-A/P card controls whether FMEC cards on it s side of the shelf appear in the CTC graphical
user interface (GUI). For example, if the MIC-A/P is removed from the shelf, FMECS to the left of the
card may disappear in CTC. This is normal behavior be cause when the MIC-A/P card is removed,
communication can no longer be established with the disappeared FMECS. For more information, refer
to the IMPROPROMVL entry in the “Alarm Troubleshooting” chapter of the CiscoO NS 15454 SDH
Troubleshooting Guide.
