Establishing a Serial Connection to the Device

To establish a serial connection to the console port on the device, complete the following steps.

Verify that the device is powered on and that POST is complete by verifying that all power LED indicators on the power supplies, fans, and blades display a steady green light.
Remove the shipping cap from the console (I0I0) port on the active CP blade. The active CP is indicated by an illuminated blue LED on the CP blade front panel.

Note: The console or serial port is intended primarily for the initial setting of the IP address and for service purposes.
Use a serial cable (not provided with the chassis) to connect the console (serial) port on the active CP to a computer workstation.

Note: The active CP is indicated by an illuminated blue LED, labeled "Active," on the CP blade front panel.

If the serial port on the workstation is RJ-45 instead of RS-232, remove the adapter on the end of the serial cable and insert the exposed RJ-45 connector into the RJ-45 serial port on the workstation.
Access the device using a terminal emulator application (such as HyperTerminal in a Windows environment or TIP in a UNIX environment).
Disable any serial communication programs running on the workstation (such as synchronization programs).
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:
  
  Parameter Value
  
  Bits per second 115200
  
  Data bits 8
  
  Parity None
  
  Stop bits 1
  
  Flow control None
Note:
Flow control is not supported on the serial consoles when the serial consoles are attached to remote terminal servers and must be disabled on the customer-side remote terminal server and the host-side clients.
- In a UNIX environment, enter the following string at the prompt:
```
tip /dev/ttyb -115200
```
  ß
If ttyb is already in use, use ttya -115200 instead.

When the terminal emulator application stops reporting information, press Enter . The following logon prompt displays:
```
CP0 Console Login:
```
Note:
CP0 in the preceding prompt is an example. CP1 displays in the prompt if it is the active CP.
Log on to the console using admin as the default logon name and password as the default password. As logon to the device occurs, you are prompted to change the device passwords.
```
Please change passwords for switch default accounts now. 
Use Control-C to exit or press 'Enter' key to proceed.
```

Press Enter to step through a procedure to change the passwords as shown in the following example. To skip modifying the password, press Ctrl+C .

for user - admin
Changing password for admin
Enter old password:
Enter new password:
Re-type new password:
passwd: all authentication tokens updated successfully

Passwords can be 12 to 510 characters long. Passwords must contain at least one lower case, one upper case, one number, and one special character. Passwords must not contain any repeat of characters or sequence of characters. The colon : punctuation character is not supported. Passwords are case-sensitive, and they are not displayed when you enter them on the command line.

Record the passwords exactly as entered and store them in a secure place because recovering passwords requires significant effort and fabric downtime.

For more information on passwords, refer to the Brocade Fabric OS Administration Guide.
