Channel-Select Switch Settings

All ONline media modules are equipped with the technology to work with the ONline System Concentrator's unique TriChannel™ Architecture. This architecture lets you assign the module to any of three channels on the ONline System Concentrator backplane. Refer to Chapter 1 in the ONline System Concentrator Installation and Operation Guide for a complete discussion of ONline's TriChannel Architecture.

The channel-select switches on the Bridge Module enable you to assign the module to bridge any two backplane channels, or to bridge one backplane channel to the AUI port on the front of the module. Both channels must be running Ethernet/IEEE 802.3.

Switch 1 is factory-set to the Off position and switches 2, 3, and 4 are factory-set to the On position. Therefore, the Bridge Module is initially configured to bridge the AUI port on the front of the module to backplane channel 1. The default settings are highlighted in the Table 2-2. To configure the module to bridge different channels, refer to the information in Table 2-2.

Table 2-2. Channel Select Dip Switch Settings

Port 1	Switch 1	Switch 2	Port 2	Switch3	Switch4

If you have an ONline network management module installed in your concentrator, you can remotely override these switch settings. Refer to the appropriate ONline Management Module Installation and Operation Guide for information on remotely managing the ports.
