Upgrading Firmware through the Serial Port
You can upgrade the system firmware of a switch module by connecting your computer to the
serial console port of the Integrated Administrator and using terminal emulation software that
supports the ZModem or XModem protocol. This procedure is only necessary if your
interconnect switch does not have access to a TFTP server, or if the firmware procedure was
previously interrupted and the switch module is not booting properly.
To download a firmware file to a switch module and change the external console port
baud rate:
1. From a PC using Microsoft® Windows® HyperTerminal or any other terminal emulation
program, connect to the serial console interface on the switch module at 9600 baud.
NOTE: For information on how to connect to the switch module menu-driven interface, refer to the
section “Connecting to the Switch Modules” in the menu-driven interface reference guide.
2. Reboot the switch module by using the Reboot menu option, or by pressing the
connection escape keys (usually Ctrl+Shift+_) and accessing the Integrated
Administrator Reboot Switch option. The boot procedure runs the Power-On Self-Test
(POST) and a screen similar to the following is displayed.
