Terminal serial port specifications
Each CP card provides a terminal serial port with a DB–9 connector with an
RS–232 signal subset.
Note: For dust and ESD protection, a cover is provided for the serial port and
should be kept on the port whenever the serial port is not being used.
The terminal serial port is intended primarily for use during the initial setting of the
IP address and for service purposes.
A 3.0 m (10 ft) serial cable is provided with the switch. You can convert it from a
DB–9 serial cable to an RJ–45 style serial cable by removing the adapter on the
end of the cable.
You can use the terminal serial port to connect to a computer workstation or
terminal without connecting to the fabric. The terminal device should be configured
to 9600 baud, 8 data bits, no parity, 1 stop bit, with no flow control.
The terminal serial port requires a straight through serial cable with a female 9-pin
D-SUB connector. Use the pinouts listed in Table 16 on page 88.
