Customizing V.35-Compatible Units
Making Changes in Switchpack Mode
When operating in Switchpack Mode, you can change configuration options by moving switches on the board hardware.
To enable Switchpack Mode, refer to Switching Between Terminal and
Switchpack Modes in Chapter 3, Using Terminal and Switchpack Modes.
"Procedure
Use electrostatic discharge (ESD) protection when handling the circuit board. To open the unit and make changes while in Switchpack Mode:
1.Power down the unit and remove the enclosure cover, exposing the circuit board.
2.Find the switchpack for the configuration options you wish to change. Switchpack positions are defined in Appendix C, Switchpacks and Jumpers.
3.Place the switchpacks in the correct position for each desired configuration option. The switchpacks are not preconfigured.
For example, to change a unit's card type from CO to CP, move switch 1 on switchpack S1 to the OFF position.
4.Verify that switches 4 and 5 on switchpack S1 are set to ON and OFF, respectively.
5.Replace the cover and screws.
6.Power up the board to reset and enable the new configuration.
