Appendix A: Flash Upgrades
The DSR switch Flash upgrade feature allows you to update your appliance with the latest
firmware available. This update can be performed using the DSView 3 software, using a Trivial
File Transfer Protocol (TFTP) server or using the on-board web interface.
After the Flash memory is reprogrammed with the upgrade, the DSR switch performs a soft reset,
which terminates all IQ module sessions. A target device experiencing an IQ module firmware
update may not display, or may display as disconnected. The target device will appear normally
when the Flash update is completed.
NOTE: During an upgrade, the IQ module status indicator in the OSCAR interface Main dialog box is yellow.
CAUTION: Disconnecting an IQ module during a firmware update or cycling power to the target device will
render the module inoperable and require the IQ module to be returned to the factory for repair.
Using the DSView 3 software
To upgrade the DSR switch firmware using the DSView 3 software:
The preferred method for updating the firmware is to use the DSView 3 software. See the DSView
3 Installer/User Guide for detailed instructions.
Using the Console menu interface
To upgrade the DSR switch firmware using the Console menu interface:
NOTE: You may only update the DSR switch firmware using the Console menu interface when using IPv4 mode.
NOTE: If you do not have a TFTP server, you can find several shareware and freeware programs on the Internet
that you can download and install.
1. Visit http://www.avocent.com/support and download the latest Flash firmware from Avocent.
2. Save the Flash upgrade file to the appropriate directory on the TFTP server.
3. Use the supplied ribbon cable and either an RJ-45 to DB9 (female) adaptor or a null modem
cable to connect a terminal or PC running terminal emulation software (such as
HyperTerminal) to the SETUP, CONSOLE or 10101 port on the back panel of the DSR switch.
The terminal should be set to 9600 bps, 8 bits, 1 stop bit, no parity and no flow control.
4. If the DSR switch is not on, turn it on now. After approximately one minute, press any key to
access the Console Main menu.
5. Select the Firmware Management option from the Console Main menu.
