switch to operate in Buffer Mode.
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.
Once you configure the
Remote Console Port Manager
for your application, you can save
your parameters and options to
an ASCII text file on your PC. Doing
this enables you to quickly restore
user-selected parameters if the
unit configuration is accidentally
altered or deleted. You can even
upload saved parameters to other
Remote Console Port Manager
units—a useful function when you
want to quickly set up several units
that are configured with identical
or similar parameters.
Ports and switches.
There are two types of ports
on the back panel: a Network Port
and eight or sixteen RS-232 Ports.
The Network Port is an RJ-45
Ethernet port (a 10BASE-T
interface) for connection to your
TCP/IP network. To communicate
via a network, you need only to
specify an IP address, subnet
mask, and gateway address.
Standard DB9 connectors
configured as DTE ports, the
RS-232 Ports are used for
connecting to console ports on
This is just one of many possible installation configurations for the Remote Console
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.
•
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.
•
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-

level commands; if a port password is entered, the unit only recognizes user-
level commands. As noted earlier, supervisors are allowed to adjust port
configuration, connect to any port, or review unit status, but users are only
allowed to review status and connect to the ports allowed by their port
password.
•
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.
•
Ports 12, 14, and 16 (User Ports):
The port password
COLOCATION2
has been
assigned to these three ports. If the switch 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 12, 14, and 16.
NOTE: In this example, Ports 3 through 16 could also be a mixture of ports
connected to external modems and ports connected to devices such as file
servers or archives. This set-up would enable remote users to dial in and
access a specific file server or archive as long as they enter a valid port
password at login.
