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.
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 2 lists the serial cable pinouts.
Assigning permanent passwords
When you log in for the first time, Brocade recommends that you change the passwords for the default accounts.
The factory-configured default accounts on the switch are admin, user, and root. Use the default administrative
account as shown in Table 3 to log in to the switch for the first time and to perform the basic configuration tasks.
