I/O panel connections

553-3001-210 Standard 14.00 June 1999
Appendix C: Backplane cabling in NT8D11 and NT8D37 modules
Note: The corner vertical channels in the rear of the module are outside
of the EMI shield. Cables in those vertical channels must be shielded, and
must enter and exit the EMI-shielded area through I/O panels and
adapters.
Tip, ring, A, B, E, M, ESC, and ESCG connections may be considered
to be Telecommunications Network Voltages (TNV).
1 Select an appropriate number of NE-A25B (or equivalent) cables long
enough to run from the I/O panels on the rear of the module to the MDF.
2 Attach a tag that shows the module number and the I/O connector
designation to both ends of each cable.
3 Connect each cable to the appropriate connector on the I/O panel and run
the cables to the MDF.
4 Terminate each cable on the cross-connect block designated with the
appropriate module number.
Note: Refer to "Planning and designating the Modular Distribution
Frame (MDF)" on page 67 for information on the MDF layout.
5 Make sure all cables are neatly run, properly seated, and secured with
cable ties.
