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 software or using a Trivial File Transfer Protocol (TFTP) server.
After the Flash memory is reprogrammed with the upgrade, the DSR switch performs a soft reset, which terminates all DSRIQ module sessions. A target device experiencing a DSRIQ 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 DSRIQ module status indicator in the OSCAR Main dialog box will be yellow.
CAUTION: Disconnecting a DSRIQ module during a firmware update or cycling power to the target device will render the module inoperable and require the DSRIQ module to be returned to the factory for repair.
To upgrade the DSR switch firmware using the DSView software:
The preferred method for updating the firmware is to use the DSView software. See the DSView Installer/User Guide for detailed instructions.
To upgrade the DSR switch firmware using the Console menu interface:
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.

7.Enter the name of the file that you downloaded from the Avocent web site.
8.Confirm the TFTP download by typing a y or yes and pressing Enter.
9.The DSR switch will verify that the file you downloaded is valid. Next, you will be prompted to confirm the upgrade. Type a y or yes and press Enter to confirm.
