2.4 Configuration Setting
2.4.1 Hardware Configuration Setting
Other than exceptions noted below, most configurations are software programmable. Users should not need
to remove any plug-in cards for modifications other than mentioned below.
2.4.2 Software Configuration Setting
The system configuration is stored within the main chassis. When a plug-in card is inserted, the
configuration for that card will be the factory default until changed by the user. There are three system
configurations:
Factory default - There is a factory default for each type of plug-in card
Current working
User-stored
Factory default configurations are not changeable. Each Loop-V 4200 series is shipped with all three
configurations set to the factory default configuration.
The current working configuration can be changed at any time. The system stores the current working
configuration into nonvolatile memory. When the system is turned off and then turned back on again, the
previous working configuration is retrieved as the current working configuration.
The current working configuration may also be saved into nonvolatile memory as a user-stored configuration.
The user-stored configuration may be retrieved at any time. Retrieving the user-stored configuration
overwrites the current working configuration. The user can view the stored unit configuration using the
terminal command "R" before retrieving it.
The following steps can be used to restore the controller card to the factory default configuration:
1. Press the ESC and ENTER key during power-up, while "SELF TEST" is displayed on the front panel LCD.
2. Verify that LOAD DEFAULT CONFIGURATION is being displayed on the front panel to indicate that the
operation was successful.
Each of the plug-in cards can be returned to factory default setting through commands from the controller
card.
2.4.3 Replacement of Plug-in Card
When a plug-in card is removed and replaced with a card of a different type, default configuration is assigned
to the new card. The user must set the configuration for each change of card type. If the same type card is
inserted, depending on card type, then the following happens:
y For E1, T1, and DTE plug-in cards, the previous configuration is automatically downloaded.
y For Router plug-in card, the factory default configuration is assigned to the new card.
y For E1/ T1 ATM Frame Relay plug-in card, (a) The port configuration for E1 or T1 is automatically
downloaded, (b) The Frame Relay management setup is factory default configuration.
