Activating the Special Operations Mode and Default Settings
On Blue Heat/Net models with software selectable line interfaces, there is a small reset button
located on the rear surface. On two port models, it is located between the DB-9 connectors. This
push button can be used to perform special operations, such as resetting the unit to its default
settings, or to force port scanning in situations where the SCM is not accessible.
Using the Reset Button to activate the Special Operations Mode
To activate the Special Operations Mode, hold the reset button while the unit is powering up.
Hold the button until all the port LEDs blink rapidly. Release the reset button. The port LEDs
will continue to flash rapidly after the reset button is released to indicate the Special Operations
Mode is active.
Selecting a Special Operation
After the Special Operations Mode has been activated (Reset Button), there are four options as
described below:
1. Abandon the Special Operations Mode
To abandon this mode without selecting a special operation, press and hold the reset
button for at least four seconds. While the button is pressed, the rapid flashing of the
port LEDs will stop. After four seconds, the rapid flashing will resume, you can now
release the reset button. After you release the button, the port LEDs will all be off,
indicating that the Special Operations Mode has terminated.
2. Cancel a Special Operation
If you need to cancel a special operation after it has been selected, repeatedly press the
reset button until all the port LEDs begin to flash rapidly. Then abandon the Special
Operations Mode by pressing the reset button for four seconds, as explained above.
3. Select a Special Operation
Operations are selected by repeated short presses of the reset button. Each time the
reset button is pressed; it is counted and represented on the port LEDs as a binary
number, with the port 1 LED the least significant bit. (see Table 1). Choose the
operation which you want to perform. If you miss the selection which you want (press
the button too many times), keep pressing the button, the count starts over again once it
reaches 7 (1111 binary).
4. Activate a Special Operation
To activate a selection, press and hold the reset button for at least four seconds. During
this time, the rapid flashing of the port LEDs will stop. When the rapid flashing
resumes, you can release the reset button. The port LEDs will turn off, indicating that
the Special Operations Mode has been activated.
