Twisted Pair Connectors and Cables
You can use many types of cables and connectors to link your Security
Module to your network. Use the information in this section to ensure that
the cables and connecting hardware meet requirements.
Note: For proper operation, use only approved cables when you
install all equipment.
3Com recommends that you connect cables first at the active concentrator
location, and connect transceivers second. Refer to the ONline System
