• Set-Up Switch Three is included as a spare, and is not used.
• When Set-Up Switch conﬁguration is changed, it is not necessary
to reinitialize the unit; Set-Up Switch settings are read whenever
the unit is powered up, and each time the command mode is
accessed via the Console Port. Settings for Switch 4 (Modem
Speaker) will be applied immediately.
4.3. Reset to Defaults
This procedure will reset all parameters to default settings and reboot the
NetLink II unit. When the unit is shipped from the factory, defaults are
reset and the memory is cleared. However, if the NetLink II has been
previously installed, this procedure should be performed.
• When this procedure is performed, all menu deﬁned parameters
will be cleared. If you wish to preserve conﬁguration settings,
parameters should be saved (as described in Section 14.2), before
beginning this procedure.
• All SSH keys will be cleared during this default procedure.
• The Reset Procedure will also clear all network port settings,
disable Telnet capability and erase any stored data.
To reset parameters to default settings and reboot the unit, ﬁrst power
the unit on and then wait for the RDY Indicator to ﬂash. Next, press and
hold the Default Button (located on the back panel.) Continue to hold
the Default button (for approximately ﬁve seconds) until the front panel
memory indicators ﬂash.
After the memory indicators ﬂash, release the Reset Button; the NetLink II
will reboot and reset default parameters. Note that after the Reset
procedure is performed, it will take approximately two to three minutes for
the NetLink II to reboot. This delay is due to the time required to generate
new SSH keys.
