Appendix A: FLASH Upgrades
The DSR FLASH upgrade feature allows you to update your unit with the latest
firmware available. To perform this update, you will first need a Trivial FTP
(TFTP) server. If you do not have a TFTP server, there are several shareware
programs that you can download.
You can find a freeware TFTP server at http://klever.net/kin/canned/
PumpKIN.exe
Next you will need to download the latest FLASH firmware from Avocent at
http://register.avocent.com/ . Save the FLASH upgrade file to the appropriate
directory on the TFTP server.
Once this is complete, the following step will upload the new FLASH file.
To upload a new FLASH fi le
1. Connect a terminal or PC running terminal emulation software (such as
HyperTerminal) to the confi guration port on the back panel of the DSR
using the supplied null-modem cable. The terminal should be set to 9600
baud, 8 bits, 1 stop bit, no parity, no fl ow control.
2. If the DSR is not on, turn it on now. After approximately 10 seconds, press
any key to access the main menu.
