Software Rollback
Software rollback (also referred to as image rollback) essentially allows the OmniSwitch 6600 series
switches (in both standalone and stacked configurations) to return to a prior “last known good” version of
software in the event of a system software problem. The switch controls software rollback through its
resilient directory structure design (i.e., /flash/working and /flash/certified).

For detailed information on the software rollback feature, as well as the switch’s /flash/working and

Hot Swapping
Hot swapping refers to the action of adding, removing, or replacing back up power supplies, as well as
uplink modules and MiniGBICs, without powering off your switch and disrupting other components in the
switch or stack. This feature greatly facilitates hardware upgrades and maintenance and also allows you to
easily replace components in the unlikely event of hardware failure. The following hardware components
can be hot swapped:

can be hot swapped:
• OS66BPS-100A Back Up Power Supply
• OS6600-GNI-C2 Gigabit Ethernet Uplink Submodule
• OS6600-GNI-U2 Gigabit Ethernet Uplink Submodule
• MiniGBICs installed in the OS6600-GNI-U

Gigabit Ethernet Uplink Submodule; MiniGBICs include:
- MiniGBIC-SX
- MiniGBIC-LX
- MiniGBIC-LH-70
Note. Stacking modules cannot be hot swapped at any time. For information on stacking modules, refer to

Hardware Monitoring
Automatic Monitoring
Automatic monitoring refers to the switch’s built-in sensors that automatically monitor operations. If an
error is detected (e.g., over-threshold temperature), the switch immediately sends a trap to the user. The
trap is displayed on the console in the form of a text error message. (In the case of an over-threshold
temperature condition, the chassis displays an amber TEMP LED in addition to sending a trap.)
