In case the KN1000 cannot be accessed with the usual LAN-based methods, it
can be accessed with an external modem via the switch’s RS-232 port. To
enable support for PPP (modem) operation, click to put a checkmark in the
Enable Out of Band Access checkbox.
Note: 1. Enabling out of band access automatically enables Dial In operation.
See PPP Modem Operation , page 159, for set up and operation
details.
2. For the modem session, the KN1000 has an IP address of
192.168.192.1; the user side has an IP address of 192.168.192.101.
When you enable out of band access, the Enable Dial Back , and Enable Dial
Out functions become available, as described in the sections that follow.

the connections that dial in to it, and dials back to one of the entries described
in the table below:
