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 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 interface Main dialog box is 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.
