Establishing a serial connection to the device

About this task

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

Procedure

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 the serial cable provided with the device 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
  
  9600
  
  Data bits
  
  8
  
  Parity
  
  None
  
  Stop bits
  
  1
  
  Flow control
  
  None
  
  Note: Flow control is not supported on the serial consoles when 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 -9600
```
  If ttyb is already in use, use ttya -9600 instead.
  
  When the terminal emulator application stops reporting information, press Enter. The following login prompt displays:
```
CP0 Console Login:
```
  Note: CP0 in the preceding prompt is an example. "CP1" will display if it is the active CP.
Log in to the console using admin as the default login name and password as the default password. As login 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 8 to 40 characters long. They must begin with an alphabetic character. They can include numeric characters, periods (.), and underscores (_) only. Passwords are case-sensitive, and they are not displayed when you enter them on the command line. For more information on passwords, refer to the Fabric OS Administrator's Guide.
