DB9 Serial Port
(on the Hub Side)
The DB9 serial port on the front panel is used to connect the
hub to a management device. The VT-100 console interface
can be accessed from a terminal, a PC running a terminal
emulation program, or from a remote location via a modem
connection. Network management software (which provides a
graphical interface) can also be used to discover and map the
hub from a remote location via a modem connection, running
SLIP over TCP/IP. You can use the serial port to configure
port settings (e.g., enabled or disabled), or to update device
firmware. The pin assignments used to connect various device
types to the hub’s Console Port are provided in the following
tables.
