Appendix A: FLASH Upgrades
You can use the DSR1021/1022 switch FLASH upgrade feature to update your appliance with the
latest firmware available. You can perform this update by using the DSView 3 software or by using
a Trivial File Transfer Protocol (TFTP) server.
After the FLASH memory is reprogrammed with the upgrade, the DSR1021/1022 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.
