Chapter 3 Configuring the Device

Upgrading the Firmware During the Boot Process

1.Connect your computer to the NetScreen-5000 Series system:

a.Using a serial cable, connect the serial port on your computer to the console port on the NetScreen-5000 Series system. This connection, in combination with a terminal application, enables you to manage the NetScreen device.

b.Using an Ethernet cable, connect the network port on your computer to the management port on the NetScreen-5000 Series system. This connection enables the transfer of data between the computer, the TFTP server, and the NetScreen device.

2.Make sure that you have the new ScreenOS image file stored in the TFTP server directory on your computer. For information on obtaining the new firmware, see the NetScreen Concepts & Examples Reference Guide.

3.Run the TFTP server on your computer by double-clicking on the TFTP server application. You can minimize its window but it must be active in the background.

4.Log in to the NetScreen-5000 Series system using a terminal emulator such as HyperTerminal. See “Establishing a Terminal Emulator Connection” on page 25. Log in as the root admin or an admin with read-write privileges.

5.Power on or reboot the NetScreen-5000 Series system.

6.Keep your eyes on the terminal emulator screen, then when you see “Hit any key to load new firmware”, press any key on your computer keyboard to interrupt the startup.

Note: If you do not interrupt the NetScreen-5000 Series system in time, it proceeds to load the firmware saved in flash memory.

7.At the Boot File Name prompt, enter the file name of the ScreenOS firmware you want to load.

8.At the Self IP Address prompt, enter the IP address of the NetScreen-5000 Series system that is used to communicate to the TFTP server.

9.At the TFTP IP Address prompt, enter the IP address of the TFTP server.

An indication that the firmware is loading successfully is the display of the series of “rtatatatatata...” running on the terminal emulator screen and a series of symbols running on the TFTP server window. When the firmware installation is complete, a message informs you of the success of the installation.

10.Answer Yes to the following question: “Program to on-board flash” ([y]/n)” Answering “yes” saves the firmware you installed to flash memory.

11.Answer Yes to the following question: “Run downloaded program? ([y]/n)”

Answering “yes” instructs the NetScreen-5000 Series system to start running the new ScreenOS firmware.
