Making Changes in Switchpack Mode
5-4
When operating in Switchpack Mode, you can change configuration options by
moving switches on the board hardware.
To enable Switchpack Mode, refer to
Switchpack Modes in Chapter 3.
Procedure
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. Use electrostatic discharge (ESD) protection when handling the circuit
board.
2. Find the switchpack for the configuration options you wish to change.
Switchpack positions are defined in Appendix C,
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. Make sure that positions 4 and 5 on switchpack S1 are set to ON and OFF,
respectively, in order to use the HDSL loop for the clock source.
5. Replace the enclosure cover and power up the board to reset and enable the
new configuration.
