This “snapshot” of the last 32K
of received data is stored in non-
volatile memory and can be
viewed, saved, or erased at any
time. This feature is particularly
useful when alarm information,
or other critical data, is sent to a
specific port during non-connect
periods.

You’re also provided with
several control options. The
Remote Console Port Manger
can be controlled by a local PC
(communicating with the switch
via cable) or controlled remotely
via an external modem or Telnet
connection. Just use a terminal
emulation or Telnet program to
send commands for connecting
ports or displaying status.

Port Manager. In this example, ports have been configured as follows:
• Network Port: This port enables Telnet access by remote supervisors and/or
users. When a Telnet connection is established, the switch prompts the caller
to enter a password. If the supervisor password is entered, the unit recognizes
supervisor-level commands; if a port password is entered, it only recognizes
user-level commands. Supervisors are allowed to adjust port configuration,
connect to any port, or review unit status. Users, however, are only permitted
to review status and connect to ports that are allowed by their port password.

user-level commands. Supervisors are allowed to adjust port configuration,
connect to any port, or review unit status. Users, however, are only permitted
to review status and connect to ports that are allowed by their port password.
• Port 1 (System Set-Up Port): In this application, this port has been left open so
on-site service personnel can access the switch’s Command Mode without
disrupting other ports. Because Port 1 is the System Set-Up Port, the service
tech is allowed password-protected access to supervisor-level commands,
and is able to connect to any port, change configuration, or display unit status.

tech is allowed password-protected access to supervisor-level commands,
and is able to connect to any port, change configuration, or display unit status.
• Port 2 (Modem Port): An external modem has been installed here, and the port
has been configured for Modem Mode. This mode allows definition of a modem
reset string, initialization string, and hang-up string. When a caller contacts the
Remote Console Port Manager via a modem, a password prompt is displayed.
If the supervisor password is entered, the switch permits access to supervisor-
reset string, initialization string, and hang-up string. When a caller contacts the
Remote Console Port Manager via a modem, a password prompt is displayed.
If the supervisor password is entered, the switch permits access to supervisor-

• Ports 5, 7, and 9 (User Ports): The port password COLOCATION1 has been
assigned to these three ports. If the Remote Console Port Manager is contacted
via the Network Port or Modem Port, and this password is entered at login,
users are only able to review status and connect to the devices that are
attached to Ports 5, 7, and 9.
