DS.11 FAQ

A-5

Firmware

Can the BU-DS.11/RB-DS.11 firmware be upgraded?

The firmware in the BU-DS.11/RB-DS.11 is stored in flash and can be upgraded

using the built in Configuration Utility or the TFTP server.

Can the BU-DS.11/RB-DS.11 flash be erased or the firmware changed by an

unauthorized person?

The flash is protected against unauthorized access. The TFTP server in the

BU-DS.11/RB-DS.11 requires the SNMP write community name (password) to

perform an upgrade.

Can the firmware flash be corrupted when upgrading to a new version?

If the TFTP file transfer is interrupted during a flash update the loaded firmware

may be corrupted. The DS.11 has two flash memories: Current and Shadow. The

new firmware is loaded as the shadow version. If the newly loaded firmware is

corrupt, then the unit can continue operation using the primary (current) version.

Can DS.11 firmware be downgraded?

An earlier version of firmware can be loaded and used by the units.

Can the previous version of firmware be kept?

The previous version is maintained in the flash memory, and the user can switch

between the two versions using the Flash Control commands.
