Serial port specifications
The serial port is located on the port side of the switch. The switch uses an RJ45
connector for the serial port. An RJ45 to DB9 adaptor cable is also provided with
the switch.
Note: To protect the serial port from damage, keep the cover on the port when not
in use.
The serial port can be used to connect to a workstation to configure the switch IP
address before connecting the switch to a fabric or IP network. The serial port’s
parameters are fixed at 9600 baud, 8 data bits, and no parity, with flow control set
to None.
Table 15 lists the serial cable pinouts.
