3.17 MIC-A/P FMEC
Figure 3-18 MIC-A/P Faceplate and Block Diagram
The MIC-A/P FMEC has the following features:
• Connection for one of the two possible redundant power supply inputs
• Connection for eight alarm outputs (coming from the TCC2/TCC2P card)
• Connection for four configurable alarm inputs/outputs
• Connection for sixteen alarm inputs
• Storage of manufacturing and inventory data
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 its 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 might disappear in CTC. This is normal behavior because 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 Cisco ONS 15454 SDH
Troubleshooting Guide.
Table 3-16 shows the alarm interface pinouts on the MIC-A/P DB-62 connector.
