A.2 Upgrading Firmware via the Serial Port
You can upgrade system firmware by connecting your computer to the serial port on the switch, and
using a console interface package that supports the XModem protocol. (See “3.2 Required Connections”)
1. Restart the system by using the Restart System command; or by pulling out the power cord to reset
the power, waiting five seconds, and plugging it back in.
2. When the system initialization screen appears as shown above, press “D” to download system
firmware, and then indicate the code type (<r> Runtime image or <d> Diagnostic image).
3. Change your baud rate to the selected value, and press Enter to enable download. From the terminal
emulation program, select the file you want to download, set the protocol to XModem, and then initialize
downloading.
NOTE:
1. If you use Windows HyperTerminal, disconnect , set the baud rate, and reconnect .
2. The download file should be a binary file or an image file; otherwise the agent will not accept it.
4. After the file has been downloaded, the console screen will display information similar to that shown
below. Press Enter to download to permanent memory, change the baudrate back to 19200, press Enter
to start decompressing the new firmware, and then press Enter to open the Logon screen.
