Connect Meridian 1 modules to the MDF

Meridian 1 modules connect to the MDF using NE-A25B cables with 50-pin D-type male connectors on each end. One end of the cable plugs into the I/O panel at the rear of the Meridian 1 module and the other end plugs into the MDF.

Figure 6 shows the cable connection between the Meridian 1 and the MDF.

1Determine the number of NE-A25B cables needed to connect one module to the MDF.

2Label each end of the cable specifying the module number, the connector name (A, B, C), and the card type (SILC or UILC).

3Plug one end of a cable into the appropriate connector on the I/O panel at the rear of the Meridian 1 module. Plug the other end of the cable into the corresponding connector on the MDF.

4Properly identify cables on the MDF. For example, plug the cable into connector A on the I/O panel and into the connector labeled A on the MDF if an SILC or UILC is installed in slot 0 of an IPE module.

5Repeat steps 2 through 4 for all cables in that module.

6Repeat steps 1 through 5 for all modules containing SILCs and/or UILCs.

7Lay all the cables neatly and fasten them with cable ties.

8Label the MDF, as necessary, using Table 2 through Table 5.
