Connecting to the Serial Ports
The Cajun P120 has two serial ports – one on the front panel for connecting a PC or
terminal, and one on the back panel of the unit for connecting a modem.
The RJ-45 port on the front panel of the Cajun P120, labeled Console, may be used
for configuration of the switch using the built-in Command Line Interface (CLI,
Terminal Emulation). The SLIP serial port, on the back panel of the Cajun P120,
may be used for out-of-band SNMP management, Telnet or a TFTP server.
Their settings are as follows
•
Baud Rate - 9600 bps
• Character Size - 8
• Parity - None
• Stop Bit - 1
• Flow Control - None
The terminal connected to the serial port must be configured with the same
settings; this setting should work with any PC COM port over a DB-9 to RJ-45
connector.
* The above pinout reflects the functionality of the signals, as seen from the
Cajun P120.
