Testing

Device Reset

The DSU can be reset locally or remotely. From the Control menu, select Reset Device and press Return, then answer Yes to the verification message. The DSU reinitializes itself, performing a Device Self-Test. Refer to Table 6-2,Self-Test Results Messages, in Chapter 6.

Configuring the DSU improperly could make the user interface inaccessible, leaving it in a state where an ATI session cannot be started through the Terminal port or via a Telnet session. If this occurs, DSU connectivity can be restored with a terminal that is directly connected and set for Terminal Port option defaults.

Two methods can be used to restore access to the ATI. Both methods cause a device reset.

￿Reset Terminal Port ± Allows you to only reset the configuration options related to Terminal port usage. No security-related configuration options are changed. Refer to Table A-5,Terminal Port Options, for defaults.

￿Reload Factory Defaults ± Allows you to reload the Default Factory Configuration, resetting all of the configuration areas and control settings for security reasons. This method is useful when the user's passwords have been forgotten.

"Procedure

To reset Terminal port settings:

1.At the asynchronous terminal connected to the Terminal port, verify that the terminal's options are set to the default settings:

ÐData Rate(Kbps) to 9.6

ÐCharacter Length to 8

ÐStop Bits to 1

ÐParity to None

2.Power the DSU Off and back On. The DSU performs a power-up routine.

3.Immediately after the OK and TEST LEDs light up, press the Return key 5 times quickly in succession. The System Paused screen appears.
