Do not change or delete the IP address or access level of the NMS

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:
H
Reset 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 Self-Test. No security-related configuration options are
changed.
H
Reload 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
To reset COM port settings:
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
stop-bit, and no parity.
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.
