For example, to change the card type, enter 1 at the Config prompt. This toggles
the parameter from CP to CO. Entering 1 again changes it back to CP.
You must reset the board for changes to the card type or loops enabled
(options 1 or 2) parameters to take effect. A system message is displayed on the
terminal to remind you to reset the board. To reset the board, use option 4 from
the Main Menu. (The board may also be reset by cycling the power on the board.)
All configuration settings are stored in nonvolatile memory.
The HDSL rate type, firmware revision numbers, and serial number displayed on
the Board Configuration screen cannot be changed.
Option 5 (Switchpack Definitions) on the Config menu is used to display the
switchpack and jumper positions used when making configuration changes
manually. This menu option is described in
Displaying Switchpack Definitions
on
page 5-5.
Making Changes in Switchpack Mode
When operating in Switchpack Mode, you can change configuration options by
moving switches and jumpers on the board hardware. To enable Switchpack
Mode, refer to
Switching Between Terminal and Switchpack Modes
in Chapter 3.
Procedure
To open the unit and make changes 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 or jumper header for the configuration options you wish
to change. Switchpack and jumper positions are defined in
Switchpacks and
Jumpers
, Appendix C.
3. Place the switchpack or jumper in the correct position for each desired
configuration option. For example, to change a unit’s card type from CP to
CO, move DIP switch 1 on switchpack 1 to the ON position.
4. Replace the enclosure cover and power up the board to reset and enable the
new configuration.
