Upgrading the firmware using TFTP on Linux operating systems
NOTE: The following Linux example uses Red Hat 3.0. For more information, refer to your Linux operating
system's HELP or documentation.
To upgrade the firmware on Linux operating systems:
1. Connect one end of a serial cable to an available COM port on the server or workstation.
2. Connect the other end of the above serial cable to the serial port on the console switch.
3. Configure the terminal emulation software for the server, such as Minicom.
IMPORTANT: Minicom is a utility that is loaded during the installation of Linux. However, if you do not
select the option to install the Linux Utilities during the operating system installation, you cannot use Minicom
without downloading the Minicom X.X..i386.rpm file from the Red Hat website. (Refer to the procedure for
installing RPMs from the Red Hat website.)
To configure Minicom:
a. Log on to a Linux console, or open a terminal and enter minicom-s at the command prompt.
The Configuration menu appears.
b. Select Serial Port Setup. The Change which setting? menu appears.
c. Select Option A (Serial Device). Manually change the device type from "dev/modem" to

A—Serial Device: /dev/ttyS0
