Upgrading Firmware by Means of the Serial Port
The system firmware of a GbE Interconnect Switch can be upgraded by connecting a 
computer to the serial console port on the front of GbE Interconnect Switch and using 
terminal emulation software that supports the ZModem or XModem protocols. This 
procedure is only necessary if your GbE Interconnect Switch does not have access to a TFTP 
server, or if the firmware procedure was previously interrupted and the switch will not boot 
properly. 
To download system firmware using the current download baud rate and current download 
protocol, follow steps 1 through 4 and steps 11 through 16. 
To change the default download baud rate of 115200 and the default download protocol of 
ZModem, follow steps 5 through 9. 
IMPORTANT: Because some required actions are time critical, it is recommended that you read 
through all the steps and become familiar with the terminal emulation software before trying to 
download firmware or change the boot configuration. 
To download a firmware file to a GbE Interconnect Switch, do the following:
1. From a PC using Microsoft Windows HyperTerminal or any other terminal emulation
program, connect to the serial console interface on the GbE Interconnect Switch using the 
default values of 9600 baud, 8 data bits, no parity and 1 stop bit. 
NOTE: For information on how to connect to the switch console interface, refer to the section 
“Connecting to the GbE Interconnect Switches” in Chapter 3. 
NOTE: For faster data transfers, change the speed of your console connection from 9600 to 
115200. Remember to also change the baud rate of your terminal emulation session to match the 
console speed settings. Refer to the section “Configuring RS232 and SLIP” in Chapter 3.
