Resetting the Termination Unit's COM Port or
Factory Defaults
Misconfiguring the termination unit could render the user interface inaccessible, leaving it in a state where a session cannot be started via the COM port or a Telnet session. If this occurs, the termination unit connectivity can be restored via a terminal directly connected to the COM port.
Two methods can be used to restore access to the user interface:
HReset COM Port ± Allows you to reset the configuration options related to COM port usage. This also causes a device reset, where the termination unit performs a Device
HReload Factory Defaults ± Allows you to reload the Default Factory Configuration, resetting all of the configuration and control settings which causes the current configuration to be destroyed and a device reset. This method is also useful when the user's password(s) have been forgotten.
"Procedure

1.At the terminal that is directly connected to the unit's COM port, configure the terminal to operate at 9.6 kbps, using character length of 8 bits, with one
2.Reset the unit, then immediately and repeatedly press Enter at a rate of about 1 press per second until the System Paused screen appears.
3.Tab to the desired method, and enter yes (or y) for the selected prompt.
