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.
