Evidence of damage should be noted and reported immediately. Unpack the equipment as follows:
1. Place the container on a clean flat surface, cut all straps, and open or remove the top.

AC outlet capable of furnishing 115- or 230-VAC, in accordance with the nominal supply
power of your Fradswitch.

Connections The Fradswitch has eight, sixteen, or twenty-four RJ-45 connectors, one for each
asynchronous data channel. Appendix A of the Packet Switching Guide provides pin
allocations.
Main Links
