Service Port Cabling
You can connect a console terminal directly to the BayStack 350 switch service 
port, or you can connect a modem to the switch service port for remote access to 
the CI menus and screens. 
Console Terminal  Requirements
To connect a console terminal to the BayStack 350 switch service port, you need 
the following equipment:
An ASCII character terminal that has an RS-232 serial port, or a computer 
that has an RS-232 serial port and terminal emulation (typically a PC running 
common communications software)
A standard RS-232 serial communications cable with a DB-9 connector at one 
end for connection to the service port, and an appropriate connector (typically 
a DB-9 or DB-25 connector) at the other end for connection to the serial port 
on the console terminal
Modem Requirements
To connect a modem to the BayStack 350 switch service port, you need the 
following equipment:
A 9600 baud (or higher speed) modem is recommended. The service port 
speed is set to 9600 baud (the default factory setting), but supports 2400 to 
38400 baud, as long as the speed at both ends of the communications link are 
identical.
A standard RS-232 serial communications null-modem cable with a DB-9 
connector at one end for connection to the service port, and an appropriate 
connector (typically a DB-9 or DB-25 connector) at the other end for 
connection to the modem’s serial port.
Set the modem’s serial port speed to match the speed of the BayStack 350 switch 
service port (9600 baud is the default). See “Service Port Configuration” on 
Note: 
To ensure correct connections between the service port and the console 
terminal or modem port, refer to the service-port pin assignments in 
Appendix B, “Connectors and Pin Assignments.
