RS-232 DB-9 Console Port
The DB-9 port is an asynchronous serial console port supporting the RS-232
electrical specification. The port is used to connect the device to a console
managing the device. This interface configuration is as follows:
Eight data bits.
One stop bit.
No parity.
Baud rate is 38400 (default). Possible values of baud rate are 2400, 4800,
9600, 19200, 38400.

Cable, Port, and Pinout Information
This section describes the devices physical interfaces and provides
information about cable connections. Stations are connected to the device
ports through the physical interface ports on the front panel. For each station,
the appropriate mode (Half/Full Duplex, Auto) is set.
2.7.1
Pin Explain For RJ-45 Connector
The switching port can connect to stations wired in standard RJ-45 Ethernet
station mode using straight cables. Transmission devices connected to each
other use crossed cables. The following figure illustrates the pin allocation:
