The Ethernet Extender includes a Dual Image Flash, capable of storing two different versions of software in two
different partitions.
Upon reset (or boot; refer to
Appendix B
), the Ethernet Extender automatically runs the program stored in the
primary (active) partition.
New software versions are loaded into the secondary (backup) partition. If loading succeeds, the backup
partition becomes primary active and reset is automatically performed, running the new software version. If
loading fails, however, the device will be still capable of working, since the flash partition storing the old version
is still primary. Refer to Figure 5-42.
Figure 5-42. Using the Dual Image Flash.
Dual Image Flash can be controlled by the BOOT Manager. You use the BOOT Manager to manually define
active and backup partition, run backup partition, erase some or all information from Flash, etc. The BOOT
Manager is accessible via the above menu or immediately after resetting the hardware. Refer to
Appendix B
for
a detailed description of the BOOT Manager.
