3.0 CONFIGURATION

The 2701RC features configuration capability via hardware DIP switches, a software control port, or SNMP through the 1001MC. This section describes all possible hardware and software switch configurations of the network connection.

NOTE: The 2701RC factory default is set to DIP switch control. Software control can be enabled either through the control port or SNMP management station. Performing a hardware reset sets the unit for dip switch control.

3.1 DIP SWITCH CONFIGURATION

The Model 2701RC has two eight bit DIP switches and two rotary DIP switches that allow configuration for a wide range of applications. The switches are accessed by removing the card from the chassis.

Figure 1 (below) shows the location of the DIP switches on the top of the printed circuit board.

DIP Switches S1 and S2 can be configured as either On or Off . Figure 2 (below) shows the orientation of the DIP switches with respect to ON/OFF positions. Default position and descriptions for Switches S1 and S2 are provided on the next page.

NOTE: If you do not have a terminal, you may force the unit to use the DIP switches as the default configuration source by turning off the unit, setting all the DIP switches to the ON position, then powering on the unit. This will cause the unit to enter a special mode. Then turn off the unit and change the switch settings to the desired settings. When you turn the unit on again, the unit will be set up with the selected switch settings.

NOTE: The Model 2701RC is set to HDB3 line coding at the

factory: This setting can be changed to AMI via VT-100 menus (using the 1001CC card) or SNMP Management (using the 1001MC card).
