Procedure 8
Connect the modules to the MDF
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
Input/Output (I/O) panel at the rear of the module, and the other end plugs
into the MDF.
Figure 6 on page 30 shows the cable connection between the system and the
MDF.
1 Determine the number of NE-A25B cables needed to connect one module
to the MDF.
2 Label each end of the cable specifying the module number, the connector
name (A, B, C), and the card type (SILC or UILC).
3 Plug one end of a cable into the appropriate connector on the I/O panel at
the rear of the module. Plug the other end of the cable into the
corresponding connector on the MDF.
4 Properly 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.
5 Repeat steps 2 through 4 for all cables in that module.
6 Repeat steps 1 through 5 for all modules containing SILCs and/or UILCs.
7 Lay all the cables neatly and fasten them with cable ties.
8 Label the MDF, as necessary, using Table 3 through Table 6 beginning
