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 Concentrator Installation and Operation Guide for more information about the ONline System Concentrator connections.
