Creating a serial connection
You perform all configuration tasks in this guide using a serial connection from a workstation or
terminal to the switch.
Complete the following steps to create a serial connection to the switch.
1. Connect the serial cable to the serial port on the switch and to an RS-232 serial port on
the workstation or terminal device.
If the serial port on the workstation or terminal device is RJ45 instead of RS-232, remove the
adapter on the end of the serial cable and insert the exposed RJ45 connector into the RJ45
serial port on the workstation.
2. Open a terminal emulator application (such as HyperTerminal on a PC, or TERM, TIP, or Kermit
in a UNIX environment), and configure the application as follows:
• In a Windows environment, enter the following values: 9600 bits per second, 8 databits,
no parity, 1 stop bit, and no flow control.
• In a UNIX environment using TIP, enter the following string at the prompt:
tip /dev/ttyb -9600
If ttyb is already in use, use ttya instead.
Serial cable pinouts
The serial port is located on the port side of the Brocade VDX 6720. The switch uses an RJ-45
connector for the serial port. An RJ-45 to DB9 adaptor is also provided with the Brocade VDX 6720.
The cable supplied with the switch is a rollover cable.
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 Brocade VDX 6720 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 1 lists the serial cable pinouts.
