Serial port specifications (pinout RJ-45)

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 RS-232 adapter 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 13 lists the serial cable pinouts.
