Appendix A: FLASH Upgrades
The DSRIQ module is unavailable while an upgrade is in progress. When
an upgrade is initiated, any current connection to the server via the DSRIQ
module will be terminated. If you are using DSAuth or DSView software,
a server experiencing a DSRIQ module firmware update may not display,
or may display as disconnected. The server will appear normally when the
FLASH update is completed.
NOTE: Firmware can also be upgraded using the File - Update Firmware command in the
DSAdmin management application software. See the DSView Installer/User Guide for
more information.
NOTE: During an OSCAR interface-initiated upgrade, the DSRIQ module status indicator in
the Main dialog box will be yellow.
The DSR1021 switch FLASH upgrade feature allows you to update your
appliance with the latest firmware available. To perform this update, you will
first need a Trivial File Transfer Protocol (TFTP) server. If you do not have a
TFTP server, there are several shareware and freeware programs that you
can download.
CAUTION: Disconnecting a DSRIQ module during a fi rmware update or cycling power to the
server will render the module inoperable and require the DSRIQ module to be returned to the
factory for repair.
To upgrade the DSR switch fi rmware using the Terminal
Applications menu:
1. Visit http://www.avocent.com/support and download the latest FLASH
firmware from Avocent. Save the FLASH upgrade file to the appropriate
directory on the TFTP server.
2. Connect a terminal or PC running terminal emulation software (such as
HyperTerminal) to the SETUP port on the back panel of the DSR1021
switch using the supplied null modem cable. The terminal should be set to
9600 baud, 8 bits, 1 stop bit, no parity and no fl ow control.
3. If the DSR1021 switch is not on, turn it on now. After approximately 10
seconds, press any key to access the Main menu.
4. You will see the Terminal Applications menu with ten options. Select
option 5, Firmware Management.
NOTE: The current version of your fi rmware will be displayed on the Firmware
Management screen.
